A press tool for forming the baffle comprises a piercing tool for forming the plurality of holes and a lance and fold die for forming the bent blades.

A method for identifying an electric water heater having excessive and abnormal electricity consumption for detecting inefficiency or even a malfunction comprising the following steps: The present invention provides a method for automatic detection of inefficient household heater within a group of monitored households, implemented by a server module and a plurality of household client modules, wherein each of said a server module and plurality of household client modules comprising one or more processors, operatively coupled to non-transitory computer readable storage devices, on which are stored modules of instruction code, wherein execution of said instruction code by said one or more processors implements the following actions: acquiring data relating to each monitored household, including at least part of: environmental conditions, power consumption of each water heater, household profile parameters, and household residents' profile parameters; detect events wherein the water heater's power consumption (P) surpasses a predefined threshold (Pth), and henceforth label said detected events as “water heater activation” events; For each house (i) in the training set, and per each consumption day (d), define a binary label L.sub.id. Said label marks the water heater's activity as either ‘Normal’ or ‘Abnormal’ per house i and day d. Initialize all labels as ‘normal training a machine learning algorithm, to create at least one classification model, wherein all monitored households are classified according to said acquired data and parameters; and Using the Activation Events Classification Model after the training stage, to predict the binary label, L.sub.id, or number activation per day that a specific household (i), from beyond the household training set has surpassed a predefined number of water heater activation events (n) within a day.

A fume exhaust assembly for a gas water heater. The fume exhaust assembly comprises a fume exhaust hood; the fume exhaust hood is provided with a fume exhaust pipe; the fume exhaust pipe and the fume exhaust hood are integrally formed. By means of integral formation, an assembly operation for the fume exhaust pipe and the fume exhaust hood is saved, an assembly procedure of a gas water heater product is simplified, and thus the production efficiency of the gas water heater product can be improved.

A storage electric water heater includes a tank, an inlet tube, an outlet tube, an isolating member, and a heating device, wherein the tank has a storing space. The inlet tube and the outlet tube are disposed in the tank. The isolating member is disposed in the storing space to divide the storing space into a first chamber and a second chamber. The first chamber communicates with the inlet tube and the outlet tube. The heating device is disposed in the second chamber and includes a tube body and a heating element. Two ends of the tube body communicate with the first chamber, so that water in the first chamber could enter an interior of the tube body. The heating element is disposed on a tube wall of the tube body. Thermal energy generated by the heating element could be transferred to the interior of the tube body via the tube wall to heat up water in the tube body, thereby facilitating the thermal convection of water in the first chamber.

The present application discloses a direct-heating type heater that includes a direct-heating type heater shell, a heating device arranged inside the direct-heating type heater shell, and a direct-heating type heater component, wherein at least one segment of the heating device is installed with a metal elastic device, and the inner wall of the direct-heating type heater shell corresponding to the heating device with no metal elastic device installed is partially or wholly provided with a helical groove structure. Such a heater solves the problem of the prior art that the heat transfer efficiency is low due to the low heat dissipation capability of ceramics, and also solves the problem that water temperature is not even as water passes through the heater quickly and the water cannot be mixed fully and homogeneously.

An electromagnetic induction continuous-flow water heater, in particular an automatic beverage vending machine is provided. The heater includes: a tubular body having a longitudinal axis and at least one inlet, configured to receive water to be heated and to feed it, in use, into the tubular body, and an outlet, through which the heated water flows out of the tubular body; and an electrical winding wound around the tubular body and electrically powerable to generate an electromagnetic induction field. The tubular body is made of an electrically conductive material heated by electromagnetic induction. The heater further includes an insert housed inside the tubular body and extending along the longitudinal axis with the tubular body and the insert delimit at least between an external surface of the insert and an internal surface of the tubular body, a helical flow channel for the water, which extends helically around the longitudinal axis.

An electric heater to heat a flow of a fluid having a jacket block comprising a plurality of longitudinal bores to allow the through-flow of a gas phase medium. An elongate heating element extends through each of the bores and is positionally stabilised within the jacket block via a plurality of stabilising fins that project radially inward to at least partially surround the elongate heating element within each of the bores.

A semi-open high-temperature heat pump system including a compressor, a direct-contact condenser, a heat exchanger, an evaporator, a water purifier, a cold water pump, a hot water pump, a circulating water pump, and a vacuum pump. A discharge port of the compressor is connected to the direct-contact condenser, the direct-contact condenser is connected to the evaporator via the heat exchanger, and the evaporator is connected to a gas suction port of the compressor via a gas vent on its top. An outlet of the water purifier is separately connected to the compressor, the direct-contact condenser, and the evaporator via the cold water pump. An outlet at the bottom of the evaporator is connected to the direct-contact condenser via the circulating water pump. The vacuum pump is connected above the direct-contact condenser, and the hot water pump is connected below the direct-contact condenser.

A combined heating and power system is configured to generate energy as well capture a large percentage of energy that would otherwise be lost using components, including heat transfer components, embedded within a vessel to transfer energy in the form of heat to liquid within the vessel.
