Abstract

The invention discloses a galvanic pile heat dissipation system and method for a hydrogen energy automobile, and belongs to the technical field. The system comprises a heat exchange system, a heat dissipation system and a spraying system, the heat exchange system comprises a liquid cooling pipeline passing through the fuel cell, and a heat exchanger and a heat transfer device through with the liquid cooling pipeline passes; the heat dissipation system comprises one of a compressor or a two-phase pump, a refrigerant pipeline and a radiator through which the refrigerant pipeline passes, a heat dissipation fan is arranged on the radiator, and the vaporization spraying system comprises a galvanic pile drainage collecting device, a spraying pipe and a spray head arranged at the output end of the spraying pipe. Water produced by reaction of the fuel cell is collected and sprayed to the radiator, so that the phase change evaporative cooling function is achieved, and the purpose of efficient heat dissipation is achieved. Meanwhile, the drained water is heated and vaporized by utilizing the heat of the radiator, so that the pavement can be effectively prevented from being slippery, the normal working range of the fuel cell is ensured, the electricity conversion efficiency of the fuel cell is improved, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric stack heat dissipation, and in particular relates to an electric stack heat dissipation system and a method thereof for hydrogen energy vehicles. Background technique [0002] The hydrogen in the vehicle-mounted hydrogen fuel cell stack undergoes a chemical reaction with the oxygen in the air. In addition to electrical energy, a certain amount of heat energy is also generated. The heat will affect the performance of the fuel cell stack. Conventional radiators are used to cool the fuel cell stack coolant. The conventional use method is that the mixture of ordinary pure water and ethylene glycol conducts heat exchange with the fuel cell stack coolant through the wall of the radiator to reduce the fuel cell coolant to the required temperature range. The efficiency of conventional radiators is low, which is not conducive to on-board fuel The hydrogen usage efficiency of the battery cannot solve the p...
