Description

Technical Field

[0001] This utility model relates to a high-efficiency heat dissipation structure for energy storage devices, belonging to the field of heat dissipation technology for energy storage devices. Background Technology

[0002] Containerized energy storage systems (CESS) are innovative solutions that combine energy storage technology with standard shipping containers. With the rapid development of the new energy industry and the continuous advancement of energy storage technology, the application prospects of containerized energy storage systems in the new energy sector are becoming increasingly broad.

[0003] The core component of a vehicle-mounted energy storage device is the battery pack, which consists of multiple battery cells connected in series and parallel to store electrical energy. During operation, the battery pack generates high temperatures and requires timely cooling. Currently, the main cooling methods for vehicle-mounted energy storage devices are air cooling and liquid cooling. Air cooling systems have relatively lower cooling efficiency, so liquid cooling is preferred for energy storage devices with densely packed batteries.

[0004] The layout of traditional liquid cooling lines is limited by various factors, such as space constraints, resulting in a limited range that prevents the liquid cooling lines from fully dissipating heat from the battery. Traditional liquid cooling lines also occupy some space in the vehicle compartment, consequently reducing the space available for battery installation.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This utility model addresses the shortcomings of the prior art by providing a high-efficiency heat dissipation structure for energy storage devices. The coolant circulation channel can be built into each compartment panel, achieving comprehensive heat dissipation for the battery without occupying internal space, thus providing ample space for battery placement inside the compartment.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] A high-efficiency heat dissipation structure for an energy storage device includes a symmetrically arranged left side panel and a right side panel. A horizontally arranged support panel is installed between the left side panel and the right side panel. The two ends of the support panel along the length direction are fixedly connected to the opposing inner sides of the left side panel and the right side panel. There are multiple support panels, which are evenly distributed along the longitudinal direction. A sandwich layer for battery placement is provided between adjacent support panels.

[0009] The left side panel has a flow-dividing chamber, the right side panel has a flow-merging chamber, and the supporting panel has a coolant heat exchange channel that communicates with the flow-dividing chamber and the flow-merging chamber.

[0010] Furthermore, the supporting panel includes an upper panel and a lower panel, with multiple inclined reinforcing plates provided between the upper panel and the lower panel.

[0011] Furthermore, the top end of the stiffening plate is fixedly connected to the lower surface of the upper plate, and the bottom end of the stiffening plate is fixedly connected to the upper surface of the lower plate.

[0012] Furthermore, heat exchange channels are formed between adjacent stiffening plates. The longitudinal section of the heat exchange channels is a trapezoidal structure and an inverted trapezoidal structure, which are alternately arranged in the transverse direction.

[0013] Furthermore, a strip-shaped mounting hole for supporting the insertion of the end of the panel is provided on the inner side of the left side panel.

[0014] Furthermore, a strip-shaped mounting hole for supporting the insertion of the end of the panel is provided on the inner side of the right side panel.

[0015] Furthermore, the top of the left side panel is provided with a liquid inlet port, which is connected to the diversion chamber.

[0016] Furthermore, the top of the right side panel is provided with a return port, which is connected to the merging chamber.

[0017] Furthermore, the supporting panel has front and rear panels on both sides along its length, and doors are installed on the front and rear panels.

[0018] Furthermore, the exterior of the left side panel, the right side panel, and the front and rear panels are all provided with a heat insulation layer; the exterior of the top and bottom supporting panels are also provided with a heat insulation layer.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0020] The coolant enters the distribution chamber in the left side panel through the inlet port, and then flows into the heat exchange channels of the supporting panel to carry away the heat generated by the battery. The heated coolant enters the confluence chamber to collect, and then flows back through the return port for cooling.

[0021] This invention integrates the coolant circulation channels into each compartment panel, achieving comprehensive heat dissipation for the battery without occupying internal space, thus providing ample space for battery placement inside the compartment.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description
