Disclosed is a heat exchanger capable of exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind from the first coolant flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.

Electric vehicle thermal management systems and electric vehicles using the thermal management system, are disclosed. A passenger cabin is heated by the heat dissipated from a battery and/or a motor. A cooling circuit in the management system fluidly connects the battery, the motor and a first radiator in series. The first radiator provides a heat source to the passenger cabin by means of the heat dissipated from the battery and/or the electric motor. Under certain conditions, the electric motor is selectively separated from the cooling circuit, so that when the passenger cabin needs to be heated, the thermal management system can provide heat to the passenger cabin without affecting the heat dissipation of the battery.

A heating system and method for heating the interior of a vehicle, such as a motor vehicle, which has an air-air heat exchanger having a heat storage medium, and which is configured to transfer heat between exhaust air, drawn out of the interior, and intake air, supplied to the interior from the vehicle environment, between the exhaust air and the heat storage medium, and between the intake air and the heat storage medium.

A connecting device and an integrated assembly are provided. The connecting device comprises a reinforcing portion and a flow channel portion, wherein the reinforcing portion is in a fixed or limited arrangement with the flow channel portion. The connecting device is provided with a plurality of external interfaces which can be used for connecting to a system, and the flow channel portion comprises at least two modules and at least one interface portion; each module comprises a main body portion and a bottom plate, the main body portion is provided with recessed grooves on the side thereof close to the bottom plate, the main body portion of the first module is fixed to the bottom plate by means of welding to form at least two communicating portions, and each communicating portion comprises a space where a corresponding groove is located.

A heat conducting device in a vehicle whereby heat in the body or shell of the vehicle is transferred to the ground includes a control device, a heat transferring device, and a driving device. The heat transferring device is in the vehicle and is connected to the shell of the vehicle when the vehicle is flameout, the driving device is coupled to the control device and the heat transferring device, such that the heat transferring device is extended downwards from the vehicle, until the heat transferring device contacts the ground, thereby heat of the shell of the vehicle is transferred to the ground.

An air conditioning system includes a shaft rotated by a motor during operation. A compressor having a compressor wheel, an intake port to receive a gas from an external source, and an output port to provide the gas in a compressed state, is connected to the shaft. A turbine including a turbine wheel, an intake port to receive compressed gas, and an output port to provide the gas in an expanded state, is also connected to the shaft. Energy from expansion of the gas from the turbine drives the rotating shaft, and the rotating shaft turn the compressor wheel in order to compress the gas, which exits through the output port.

The disclosure relates to a heat exchanger, preferably for a vehicle, including an applicative stratification, wherein the applicative stratification includes at least two stratification strands, wherein the applicative stratification is configured in such a manner that when incoming air into the heat exchanger is supplied in the direction of the applicative stratification, the incoming air is spread out by means of the applicative stratification in the respective stratification strand into an associated outgoing air portion. Furthermore, the disclosure relates to an air-conditioning unit and an associated method.

A ventilation system for a vehicle having a cabin includes a segmented plenum comprising a plurality of sub-plenums that are disposed above the cabin, a perforated panel defining the ceiling of the cabin and having plurality of perforations for air communication of the plenum with the cabin, and ductwork including one or more upper main ducts, lower main ducts, vertical ducts, and seat return ducts. The ducts communicate with each other to convey air, descending from the segmented plenum through the perforated panel as a high volume, low turbulence blanket of air through the cabin, back to the segmented plenum. The ventilation system also includes an air processing unit (APU) in communication with the ductwork and operable to sterilize the air conveyed therein, and one or more fans for circulating the air in the ventilation system.

A heat exchanger and a heat pump system capable of reducing the amount of a refrigerant that accumulates in an outdoor heat exchanger during heating operation, and of decreasing the appropriate amount of refrigerant during heating operation. A vehicle-external heat exchanger is provided with a hollow first header, a hollow second header provided facing the first header, and a plurality of tubes provided between and communicating with the first header and the second header. The first header is provided with a partition plate that divides the interior of the first header. A first opening formed on a partition plate side between the upper end of the first header and the partition plate. When functioning as an evaporator, the refrigerant is supplied from the lower part of the first header or of the second header, and the first opening serves an outflow port for the refrigerant.

An HVAC air inlet housing for a vehicle includes an air inlet housing having a top portion and a bottom portion. A fresh air duct, to convey fresh air from an air inlet to a blower, is defined by the air inlet housing. A water inlet port, to connect to an evaporator drain port via a hose, is defined in the bottom portion. The hose is to convey water from the evaporator drain port to the water inlet port. A water tunnel is defined by the air inlet housing to convey water from the water inlet port to a sluice defined in the bottom portion. The sluice is to convey water from the water tunnel to a sump defined in the bottom portion. A sump drain port is defined in the air inlet housing bottom portion in fluid communication with the sump to drain water from the sump.
