Hydrogen fuel cell forklift cooling system

Abstract

The invention discloses a hydrogen fuel cell forklift truck cooling system, which relates to the technical field of battery cooling and comprises a radiator and an expansion water tank which are fixedly mounted at the rear part of a forklift truck, the radiator is connected with two water pipes which are respectively used for water inlet and water outlet, one water pipe is used for being connected with the hydrogen fuel cell, the other water pipe is connected with a water pump, and a water pipe is connected between the water pump and the hydrogen fuel cell; exhaust pipes are connected between the water pump and the expansion water tank as well as between the radiator and the expansion water tank, and a water supplementing pipe is connected between the expansion water tank and the water pump. The radiator and the expansion water tank are placed at the rear part of the forklift, so that the arrangement environment temperature of the radiator and the expansion water tank is obviously lower than the internal environment temperature of the hydrogen fuel cell, and the heat dissipation performance of the hydrogen fuel cell forklift cooling system is obviously improved; and the service life and the working efficiency of the hydrogen fuel cell are effectively improved.

Description

technical field [0001] The present application relates to the technical field of battery cooling, and in particular, to a cooling system for a hydrogen fuel cell forklift. Background technique [0002] As a new energy power forklift, the performance and safety of the hydrogen fuel cell, the power source, of the hydrogen fuel cell forklift is very important, and the heat dissipation of the hydrogen fuel cell affects its use effect, which requires the heat dissipation system of the hydrogen fuel cell to be efficient and Easy maintenance feature. [0003] In the prior art, the fuel cell of the hydrogen fuel cell forklift has a box structure, and the structure is similar to the lithium battery PACK structure. The radiator, expansion tank and other components of the cooling system are installed and fixed inside the fuel cell. Many heat sources, such as stacks, batteries, air compressors, water pumps, humidifiers, water separators, etc., the ambient temperature inside the battery...

Problems solved by technology

[0004] Therefore, the cooling structure of the prior art will cause the hot air blown by the cooling fan to be unable to be smoothly discharged outside the car, resulting in low efficiency of the entire cooling system and a reduction in the efficiency of the hydrogen fuel cell; The hydrogen fuel cell box needs to be opened when the coolant is used, which affects the convenience of use; finally, because the radiator is inside the hydrogen fuel cell box, and the assembly is compact, it is inconvenient to disassemble and assemble, which will cause great inconvenience for later maintenance and needs to be improved
