Description
Technical Field
[0001] The utility model belongs to the technical field of fuel cell heat dissipation connection, in particular to a fuel cell radiator pipeline connection structure. Background Art
[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. Also known as an electrochemical generator, it represents the fourth generation of power generation technology, following hydropower, thermal power, and nuclear power. Because fuel cells convert the Gibbs free energy portion of a fuel's chemical energy into electrical energy through an electrochemical reaction, they are not subject to the limitations of the Carnot cycle and therefore offer high efficiency. Furthermore, fuel cells use fuel and oxygen as raw materials and lack mechanical transmission components, resulting in minimal harmful emissions and a long service life. Therefore, from the perspective of energy conservation and ecological protection, fuel cells are the most promising power generation technology.
[0003] After searching, Chinese patent application No. 201921636679.8 discloses a fuel cell radiator structure, including a fuel cell body, with heat conducting plates fixedly mounted on the top and bottom of the fuel cell body, and a heat sink provided on the side of the heat conducting plate away from the fuel cell body. The structure of the fuel cell radiator transfers heat from the surface of the fuel cell body to the heat sink and heat block via the heat conducting plate, and then dissipates heat from the surface of the heat block via a cooling fan. At this time, multiple heat blocks are used to increase the heat dissipation area, thereby achieving a better heat dissipation effect. The fixing block is moved outward to disengage the pin rod from the slot, and then the heat sink is lifted upward to disengage the limit rod from the fixing slot, thereby disassembling the heat sink and heat block, and cleaning them to prevent excessive dust accumulation due to long-term use from affecting their heat dissipation efficiency, thereby achieving the purpose of convenient use and better heat dissipation effect.
[0004] Although the above patent introduces the heat from the surface of the fuel cell body to the heat sink and the heat block through the heat conduction plate, and dissipates the heat from the surface of the heat block through the heat dissipation fan, at this time, the heat dissipation area is increased by multiple heat conduction blocks, thereby making the heat dissipation effect better, the fixing block is pushed outward to disengage the pin rod from the slot, and then the heat sink is lifted upward to disengage the limit rod from the inside of the fixing slot, thereby disassembling the heat sink and the heat block and cleaning them to avoid excessive dust accumulation due to long-term use affecting their heat dissipation efficiency. However, in actual use, the battery is only dissipated and dissipated through the heat conduction block, and the heat dissipation efficiency is low. When the battery works for a long time, insufficient heat dissipation and high temperature may occur, which brings inconvenience to the operator.
[0005] Therefore, it is necessary to transform it by setting up a main radiator and an auxiliary radiator in coordination, injecting cooling water into the radiator, and allowing the cooling water to circulate to absorb the heat emitted by the battery, thereby accelerating heat dissipation and improving the heat dissipation effect.

It solves the problem of only absorbing and dissipating heat from the battery through the heat conductive block, resulting in low heat dissipation efficiency, and the possibility of insufficient heat dissipation and high temperature when the battery works for a long time, which brings inconvenience to the operator.
[0007] The heat dissipation device is connected with the heat dissipation device by pipeline. The heat dissipation device is connected with the heat dissipation device by pipeline. The heat dissipation device is connected with the heat dissipation device by pipeline.
