Description

Technical Field

[0001] This utility model relates to the field of fuel cell heat exchange technology, and in particular to a spiral heat exchange tube for temperature equalization in fuel cell cooling water circuit. Background Technology

[0002] The fuel cell cooling water circuit is the core device for fuel cell stack thermal management. It uses a water pump to drive the cooling medium to circulate between the fuel cell stack cooling channels and the heat exchanger, absorbing the heat generated by the electrochemical reaction. The heat is then exchanged with the outside environment through the heat exchanger to cool down the fuel cell, maintain the stable operating temperature of the fuel cell stack, and ensure the efficient and safe operation of the fuel cell.

[0003] When fuel cells are running, local hot spots are easily generated in the stack. The uneven cooling efficiency of traditional heat exchange tubes will aggravate the temperature deviation, leading to membrane electrode degradation and catalyst deactivation. Temperature-balanced heat exchange tubes improve heat exchange uniformity by enhancing medium turbulence and secondary circulation, reducing the temperature difference between different areas of the stack, avoiding local overheating, extending battery life and improving energy conversion efficiency.

[0004] In fuel cell cooling water circuits, traditional DC heat exchange tubes suffer from poor heat dissipation due to their single flow channel and low turbulence, making it difficult to meet the uniform cooling requirements under high power density. In existing technologies, spiral heat exchange tubes have been used to improve heat exchange efficiency to some extent by extending the flow channel and enhancing fluid turbulence, which can alleviate the problem of heat accumulation in some areas. However, in actual use, spiral heat exchange tubes still have the limitation of uneven fluid distribution, resulting in significant temperature differences in different areas inside the battery. There are also significant temperature gradients between the spiral tubes, and some areas may still be too hot, making it impossible to effectively maintain the overall temperature balance of the fuel cell cooling water circuit.

[0042] Working principle: Coolant is connected to straight pipe 204 through connector 205. Straight pipe 204 serves as the main water supply channel. Coolant is distributed to each ball valve 201 through multi-way connector 203. The bottom of the servo motor 2061 of the drive assembly 206 is fixed to the top left side of the support plate 5. The first bevel gear 2062 on the right side meshes with the second bevel gear 2063 on the rear side of the valve stem 202. The servo motor 2061 drives the valve stem 202 to rotate by outputting rotational power, thereby adjusting the opening degree of the valve core of the ball valve 201 and controlling the flow channel of the corresponding spiral tube 601. The coolant flow rate is adjusted to achieve initial regulation of the flow rate in each branch channel. The top plate 701 of the temperature measuring mechanism 7 is fixed to the top of the battery casing 1, and multiple temperature probes 702 at the bottom extend into different areas inside the battery to collect temperature data in real time. Based on the temperature differences in each area, the corresponding servo motor 2061 is instructed to adjust the output torque. The flow area of ​​the ball valve 201 is changed through bevel gear transmission to dynamically balance the coolant flow rate in each spiral tube 601, so that the spiral tube 601 corresponding to the high temperature area receives coolant with a higher flow rate, thereby enhancing the heat exchange efficiency. This reduces the temperature difference between different areas inside the battery. When the coolant flows through the spiral tube 601, the outer wall of the spiral tube 601 is fixed to the inner side of the electrode plate 4. The spiral flow channel design enhances the turbulence of the coolant and expands the heat exchange area with the electrode plate 4, effectively absorbing the heat generated by the battery operation.

The two ring seats 2071 of the protective component 207 are fixed to the top right side of the support plate 5. The top fixing ring 2072 restricts the displacement of the straight pipe 204 through the circumferential structure, reduces the impact of equipment operation vibration on the pipeline connection, and ensures the stability of the flow channel system. The fixing seat 602 extends the right end of the spiral pipe 601 out of the right side of the battery case 1, providing additional support and facilitating external pipeline maintenance.
