Embodiment 1

[0036] Such as Figure 1 to Figure 7 As shown, this embodiment provides a dual-purpose intercooler for cooling and heating, including a housing 61 and a cover plate 62, the housing 61 is provided with a cavity 63, and the cover plate 62 is installed at the mouth of the cavity 63, A heating device 64 and a heat exchange device 65 are installed in the cavity 63, and a cooling liquid inlet 66 and a cooling liquid outlet 67 are provided on the housing 61, and the cooling liquid enters the inside of the housing 61 through the cooling liquid inlet 66 to exchange heat with the heating device 64 The device 65 flows out from the coolant outlet 67 after exchanging heat; the housing 61 is also provided with an air inlet 68 and an air outlet 69, and the air enters the inside of the housing 61 from the air inlet 68 and exchanges heat with the heat exchange device 65 from the air. The outlet 69 is discharged, and it is characterized in that: several temperature sensors 200 are also provided...

Embodiment 2

[0045] Such as Figure 8 and Figure 9 As shown, this embodiment is a fuel cell system, including an air filter 1, an air flow meter 2, an air compressor 3, an air compressor controller 4, an intercooler for cooling and heating, a humidifier 7, and a fuel cell The battery cell stack module 8, the coolant circulation system 10 and the fuel cell system controller 300 are characterized in that the dual-purpose intercooler for cooling and heating is the dual-purpose intercooler for cooling and heating described in Embodiment 1, and the air passes through The air filter 1 and the air flow meter 2 enter the air compressor 3, and the air compressor controller 4 controls the air compressor 3 to compress the incoming air and enter the casing from the air inlet 68 of the dual-purpose intercooler for cooling and heating In 61, after heating or cooling in the dual-purpose intercooler for cooling and heating, the air is sent to the humidifier 7 through the air outlet 69, and the humidifie...

Embodiment 3

[0048] Such as Figure 8 and Figure 9 As shown, a fuel cell system control method is characterized in that: the fuel cell system is the fuel cell system described in Embodiment 2, the fuel cell stack module 8 is controlled by the fuel cell system controller 300, and the first temperature sensor 201 detects the air temperature at the air inlet 68, the first temperature sensor 201 transmits the detected temperature signal to the fuel cell system controller 300, the air enters the air compressor 3 after passing through the air filter 1 and the air flow meter 2, and the air The compressor 3 sends compressed air to the dual-purpose intercooler for cooling and heating. When the first temperature sensor 201 detects that the air is lower than a certain set temperature value T1, the fuel cell system controller 300 controls the intercooler for dual-purpose cooling and heating. The heating function of the heating device 64 is turned on to heat the coolant entering the dual-purpose inte...

Abstract

The invention discloses a cooling and heating dual-purpose intercooler and a fuel cell system using the same. The intercooler comprises a shell and a cover plate. A cavity is formed in the shell, thecover plate is installed at a cavity opening of the cavity, a heating device and a heat exchange device are installed in the cavity, and cooling liquid enters the shell through a cooling liquid inlet,exchanges heat with the heating device and the heat exchange device and then flows out of a cooling liquid outlet. Air enters the shell from an air inlet, exchanges heat with the heat exchange deviceand then is discharged from an air outlet. The shell is also provided with a plurality of temperature sensors, and the plurality of temperature sensors are used for detecting the temperature of air and/or cooling liquid. The temperature of air in an air supply system is accurately adjusted, cold air in an air path can be rapidly and accurately heated in a low-temperature state, and high-temperature air in the air path can be rapidly and accurately cooled in a high-temperature state. The extra power consumption of operation is small, the performance is improved, and energy is saved.

Description

Technical field: [0001] The invention relates to a dual-purpose intercooler for cooling and heating, a fuel cell system and a control method. Background technique: [0002] The intercooler of the existing fuel cell is a heat exchanger, which is a device that can make two or more fluids not directly contact, but heat or energy can be transferred to each other. The working principle of the fuel cell system is: hydrogen is sent to the anode plate of the fuel cell, and oxygen is sent to the cathode plate of the fuel cell. After the catalytic reaction of the catalyst, an electron in the hydrogen atom is separated, and the electron cannot pass through the proton exchange membrane. circuit, to the cathode plate of the fuel cell, thereby generating current in the external circuit. The hydrogen ions and oxygen atoms that pass through the proton exchange membrane recombine into water. [0003] Since the oxygen supplied to the cathode plate is directly obtained from the air, as long ...
