[0039] The present invention is a modularized combined intelligent heat collector system, which comprises a PTCR-xthm electric heating chip heat source main engine 1, a data control template 2, a constant-temperature and constant-pressure device 3 and a variable-frequency water pump 4. The variable-frequency pump 4 and the PTCR-xthm electric heating chip heat source main engine 1 are connected to the data control template 2. The outlet end of the PTCR-xthm electric heating chip heat source main engine 1 is connected to the constant-temperature and constant-pressure device 3. The outlet end of the constant-temperature and constant-pressure device 3 is connected to the PTCR-xthm electric heating chip heat source main engine 1 through the variable-frequency water pump 4. The PTCR-xthm electric heating chip heat source main engine 1 consists of N (N is a natural number, which is set according to the system heating load and total power, etc.) electric heating chip heat source modules. The PTCR-xthm electric heating chip heat source main engine 1 is sequentially connected to other parts according to FIGS. 1-3.

[0040] As shown in FIG. 1, the PTCR-xthm electric heating chip heat source main engine 1 comprises an upper cover plate 1-1, a plurality of PTCR-xthm electric heating chip heat source modules 1-2, a water inlet end cover 1-3 and a water outlet end cover 1-4. The top of the plurality of PTCR-xthm electric heating chip heat source modules 1-2 is covered by the upper cover plate 1-1. The water inlet end cover 1-3 and the water outlet end cover 1-4 are respectively disposed at the end sides of the plurality of PTCR-xthm electric heating chip heat source modules 1-2. The water inlet end cover 1-3, the water outlet end cover 1-4 and the electric heating chip heat source modules 1-2 are respectively provided with a water inlet and outlet channel 1-5. The plurality of PTCR-xthm electric heating chip heat source modules 1-2 are overlapped from top to bottom. An insulation heat-conducting film 1-6 is disposed between the upper cover plate 1-1 and the PTCR-xthm electric heating chip heat source module 1-2, which is disposed underneath the upper cover plate, and an insulation heat-conducting film 1-6 is disposed between two adjacent PTCR-xthm electric heating chip heat source modules 1-2. A sealing component 1-7 is disposed at the point where the water inlet end cover 1-3, the water outlet end cover 1-4, and the electric heating chip heat source modules 1-2 are connected to exert a sealing function. The water inlet end cover 1-3 and the water outlet end cover 1-4 are metal baseplates or non-metal baseplates. The material of the metal baseplate is rare-earth aluminum alloy, stainless steel, titanium alloy or copper, or one composite material selected from aluminum bronze Cu+, aluminum steel, titanium copper Cu+, or aluminum titanium. The material of the non-metal baseplate is selected from one of the functional ceramics, glass ceramics, quartz glass or silicon resin. The PTCR-xthm electric heating chip heat source module 1-2 comprises a PTCR-xthm electric heating chip heat source baseplate 1-21 and a rare-earth thick film circuit disposed on the baseplate 1-22. The rare-earth thick film circuit 1-22 is perpendicularly overlapped on the thick film resistor circuit or horizontally distributed with the thick film resistor circuit in the form of a thick film circuit, which integrates a plurality of layers in one plane or in a plurality of curved planes. The rare-earth thick film circuit in the plane is prepared by silk-screen printing and sintering, and the rare-earth thick film circuit in the curved plane is prepared by tap casting and film bonding/HIP.

[0041] As shown in FIG. 2, the modularized combined intelligent heat collector system comprises a data control template 2, a variable-frequency water pump 4 and a heating medium cycle intelligent management system. Specifically, the outlet end of the PTCR-xthm electric heating chip heat source main engine 1 has two branches. One branch is interconnected to the user heating pipeline through a throttle valve 9 and a first stop valve 18. The user heating pipeline is interconnected to the user heat exchanger 5 and the gas collector 6, which is located higher than the user heat exchanger 5. The user heat exchanger 5 is interconnected to the heat source main engine through the first water return pipe 7, the stop valve 8 and the variable-frequency water pump 4. The other branch is interconnected to the water inlet pipe of the constant-temperature and constant-pressure device 3 through the throttle valve 9 and the second stop valve 10. The outlet pipe of the constant-temperature and constant-pressure device 3 is interconnected to the first water return pipe 7, which is located in front of the variable-frequency water pump 4, through a non-return valve 11. The water return pipe is connected to an expansion water pipe 12 through a T-branch pipe, and the water level of the expansion water pipe 12 is higher than that of the user heat exchanger 5. The power supply terminal (socket) of the heat supplying main engine is connected to the data control template 2 through a plug, and the data control template 2 is connected to a temperature sensor, which is disposed in an environment where the heat exchanger is installed.

[0042] The constant-temperature and constant-pressure device operates under the normal pressure, which is equipped with a water level indicator, a safety exhaust valve and a sensing device. The highest temperature working point is 180° C. The PTCR-xthm electric heating chip heat source main engine, the regulating valve, the constant-temperature and constant-pressure device, and the variable-frequency water pump form a circulation loop. The heating medium in the constant-temperature and constant-pressure device is conveyed to the PTCR-xthm electric heating chip heat source main engine, which returns to the constant-temperature and constant-pressure device after being heated to complete a heating cycle. The temperature of the cycle heating medium is raised by 25-30° C. every time. When the temperature of the heating medium in the constant-temperature and constant-pressure device reaches the set value, the inlet valve of the constant-temperature and constant-pressure device can be closed to allow the heating medium to directly enter into the user heating cycle system. The difference between the water supplying temperature and the water return temperature of an ordinary user cycle system is 25-30° C.

[0043] The data control template 2 comprises a temperature sensor, a microcomputer processing center, which is connected to the temperature sensor, and an executive component. The temperature sensor measures the user's indoor temperature. When the actual indoor temperature is different from the set temperature (the heating load varies), the temperature sensor sends a feedback signal to the master control center, and gives an instruction to the executive component (solid-state voltage regulator) after being processed by the microcomputer processing center. Consequently, the supply voltage and current can be regulated to control the temperature. The working state of the PTCR-xthm electric heating chip heat source module main engine 1 can also be detected by the data control template 2. The electric heating chip main engine is composed of a plurality of the heat source modules. It is very important to monitor the working temperature of the heat source module. When a failure of the variable-frequency water pump or the heating medium cycle system occurs, the failure code can be automatically displayed, or an alternate program can be automatically started to self-recover or initiate the recovering process.

[0044] Moreover, the data control template 2 adopts a microcomputer control system. The microcomputer processing center of the data control module adopts a microprocessor as the key control unit, which is equipped with a computer hardware system, a peripheral multi-channel interface circuit, a computer control circuit, and a temperature sensor closed circuit feedback system. The microcomputer processing center adopts a thermistor or rare-earth thick film temperature-sensitive control circuit. The detailed description is omitted herein.

[0045] As shown in FIG. 3, the structure of the heating medium cycle pipeline system is the following: the inlet pipe 13 of the PTCR-xthm electric heating chip heat source main engine 1 is connected to the tap water or glycol type cooling liquid tank 14; the outlet pipe 15 is connected to the inlet pipe of the constant-temperature and constant-pressure device 3; the constant-temperature and constant-pressure device 3 is provided with the water return pipe 14, which is connected to the variable-frequency water pump 4; the outlet pipe of the variable-frequency water pump 4 is connected to the PTCR-xthm electric heating chip heat source main engine 1; the variable-frequency water pump and the terminal socket/plug of the heating modules of the PTCR-xthm electric heating chip heat source main engine 1 are connected to the data control template. The outlet pipe 16 of the constant-temperature and constant-pressure device is connected to the heat exchanger 17 of the user water heater, such as a pipeline machine, a spray head or a vehicle-used heat exchanger, etc.

[0046] Another cycle mode is the following: the source water enters into the heat source main engine through the pipeline then enters into the constant-temperature and constant-pressure device after being heated; when the water temperature has not reached the set value, the valve door is closed, and the variable-frequency water pump is automatically controlled by the control template, which allows the water in the constant-temperature and constant-pressure device to enter into the heat source main engine through the water return pipe and the variable-frequency water pump so as to be reheated; After being heated to the set temperature, the water enters into the constant-temperature and constant-pressure device, which can be provided to the users via a pipeline machine, a spray head or a vehicle-used heat exchanger, etc.

[0047] The above system can also be used in the heaters of the vehicles, ships or electric cars. The system is closed when used in the heaters of the vehicles and ships. The user can adopt a vehicle-used circulating pump, and change the constant-temperature and constant-pressure device (tank) into a liquid storage tank. The outlet pipe of the liquid storage tank is connected to a heat sink, and the water return pipe of the heat sink is connected to the inlet pipe of the glycol type cooling liquid tank. All of the components must be vehicle-used, and the medium is preferred to be glycol-type cooling liquid. The heating medium is required to have high efficiency, low viscosity, high mobility, mildew prevention, scale prevention and boiling prevention.
