Description

Technical Field

[0001] This invention relates to the field of cold storage, specifically to a bent tube heat dissipation strip cold storage module. Background Technology

[0002] With the continuous development of technology, thermal management using cold storage is gradually being applied to vehicle refrigerator systems. This method offers good energy efficiency and low environmental impact, making it an economical and environmentally friendly approach to vehicle thermal management. Currently, in vehicle refrigerator cold storage modules, heat exchangers are often submerged within phase change materials. This limits the module's capacity to the volume and heat exchange capacity of the internal heat exchanger. Using smaller tube-fin heat exchangers leads to insufficient cooling capacity and slow cold storage rates. Conversely, using large-volume microchannel evaporators with high cooling capacity results in high flow resistance, limiting the amount of cold storage charge and the amount of cold that can be stored. Bent-tube heat exchangers are a highly efficient heat exchange structure, characterized by their compact structure, large heat exchange area, low flow resistance, and high flexibility, making them widely used in refrigeration systems. Combining bent-tube heat exchangers with cold storage modules allows for wider adaptation to various module sizes, further enhancing the module's integration and performance. Summary of the Invention

[0003] The purpose of this invention is to provide a bent-tube heat exchanger cold storage module, which integrates the bent-tube heat exchanger with the cold storage module and adds heat dissipation fins to enhance heat exchange. This helps the cold storage module dissipate heat more quickly. The combined effect of the bent-tube heat exchanger and the heat dissipation fins achieves efficient heat exchange, thereby helping to increase the overall cooling capacity of the cold storage module.

[0036] The cold storage module housing 2 is an open cuboid with an open front side.

[0037] The liquid outlet pipe 3 and the liquid inlet pipe 4 are installed on the right side of the cold storage module housing 2. Both the liquid outlet pipe 3 and the liquid inlet pipe 4 are installed in the center. The liquid outlet pipe 3 is installed near the upper side of the cold storage module housing 4, at a distance of one-sixth of the height of the entire right side of the cold storage module housing 2. The liquid inlet pipe 4 is installed near the lower side of the cold storage module housing 4, at a distance of one-sixth of the height of the entire right side of the cold storage module housing 2.

[0041] The bent tube 6 is wound around the heat exchanger core 5 and fitted into place;

[0042] The first additional fin 7.1 is installed on the upper side of the bent tube 6, and the width of the first additional fin 7.1 is the same as the width of the heat exchanger core 5.
