Description

Technical Field

[0001] The utility model relates to the technical field of solid hydrogen storage, in particular to a reaction heat dissipation device based on solid hydrogen storage materials. Background Art

[0002] Existing hydrolysis reaction heat dissipation devices are all experimental devices, and they all adopt the air-cooling heat dissipation principle. The reaction tank is purged by a cooling fan to make air convectively exchange heat with the outer wall of the reaction tube.

[0003] The existing cooling technology uses air cooling to exchange heat with the reaction tank. This technology is only used for small-scale hydrolysis reactions. The heat generation power of small-scale hydrolysis reactions is small, and the heat exchange area on the outer wall surface of the reaction tank can meet the heat dissipation requirements. When the amount of hydrolysis reaction increases, the reaction heat generation power will also increase. Due to the limited application scenario, the surface area of the reaction tank cannot be increased continuously. Therefore, the air-cooling method for hydrolysis reactions with a large heat generation power can no longer meet the heat dissipation requirements.

[0004] The above information disclosed in the background art section is only used to enhance the understanding of the background of the present utility model. Therefore, it may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0034] Cooling water inlet 4, which communicates with the cooling water jacket 3 and is located below the reaction tank 2;

[0035] Cooling water outlet 1, which communicates with the cooling water jacket 3 and is located above the reaction tank 2.

[0036] In a preferred embodiment of the reaction heat dissipation device based on solid hydrogen storage materials, the spiral metal water pipe has concentricity and roundness that ensure the minimum gap between the cooling water jacket 3 and the outer wall surface of the reaction tank 2.

[0043] In a preferred embodiment of the reaction heat dissipation device based on solid hydrogen storage materials, the cooling water outlet 1 is adjacent to the top of the reaction tank 2.

[0044] In a preferred embodiment of the reaction heat dissipation device based on solid hydrogen storage materials, the reaction tank 2 is a cylindrical structure.

[0045] In one embodiment, the reaction heat dissipation device based on solid-state hydrogen storage material is composed of a cooling water outlet 1, a reaction tank 2, a cooling water jacket 3, and a cooling water inlet 4. The reaction tank 2 and the cooling water jacket 3 are connected by threads and sealed with an O-ring on the cross-section to prevent the leakage of cooling water from the cooling water jacket to the outside. In the operating conditions of this device, the cooling water jacket 3 is fixedly installed, and the hydrolysis reaction material can be updated by replacing the reaction tank 2. The cooling water jacket 3 is made of metal water pipes, which are processed into a spiral shape, with connecting pipes welded to the ports and sealing structures processed on the pipe end faces. According to the external dimensions of the reaction tank 2, the spiral pipe made of pipes is machined from the inside out to process the mating surface between the cooling water jacket 3 and the reaction tank 2, ensuring the concentricity and roundness of the mating surface inside the cooling water jacket, and minimizing the gap between the cooling water jacket 3 and the outer wall surface of the reaction tank, so as to minimize the amount of cooling water short-circuiting to the greatest extent.

Along with the progress of the reaction, the reaction tank 2 system starts to release heat to the outside; the cooling water is injected into the cooling water inlet 4 by an external circulation pump. After the cooling water enters the cooling water jacket 3, it starts to spiral along the wall surface of the reaction tank 2 to increase the contact time between the cooling water and the wall surface of the reaction tank, ensuring that enough heat is carried away. The cooled water is discharged from the cooling water outlet 1 and enters the external circulating water cooling system. The external circulating water cooling system cools down the circulating water and enters the cooling water circulation water tank, and then continues to be injected into the cooling water inlet 4 by the circulation pump, and the cooling water will dissipate heat from the reaction tank in a cycle.
