Abstract

The invention provides a heat exchange system and a heat exchange method. The heat exchange system comprises a power supply subsystem and a heat exchange subsystem, the power supply subsystem comprises a battery module and is used for delivering electric energy for a terminal user, the heat exchange subsystem comprises a heat exchange module and is used for dissipating heat of the power supply subsystem, and simultaneously, recycled heat energy is used for being delivered to the terminal user. Heat energy generated by the power supply subsystem during working is managed and optimized in a unified manner, the efficiency of the system is effectively increased, the service life of the system is prolonged, and the integration level of the system is improved. Simultaneously, problems that in the prior art, energy consumption of a power supply system is high, and energy utilization rate is low is effectively are effectively resolved.

Description

technical field [0001] The invention relates to the technical field of battery heat exchange, in particular to a heat exchange system and a heat exchange method. Background technique [0002] A fuel cell is an environmentally friendly, efficient, and long-life power generation device. Taking the proton exchange membrane fuel cell (PEMFC) as an example, the fuel gas enters from the anode side, the hydrogen atoms lose electrons at the anode and become protons, the protons pass through the proton exchange membrane to the cathode, and the electrons also reach the cathode through the external circuit, at the cathode protons , electrons and oxygen combine to form water. The fuel cell converts chemical energy into electrical energy in a non-combustion manner, and its direct power generation efficiency can be as high as 45% because it is not limited by the Carnot cycle. With the battery stack as the core power generation device, the fuel cell system integrates power management, th...
