Currently, the corrosive liquid flows on the inside of the chiller structure and removes the heat through the heat conduction plate. However, in actual use of the chiller structure, the flow trajectory of the corrosive liquid is relatively single, which makes the thermal contact area of ​​the liquid smaller, resulting in a worse actual heat exchange effect, reducing the cooling power of the chiller structure, and thus affecting the heat dissipation function of the battery, and having poor practicality. Utility Model Content

[0010] Furthermore, a plurality of locking screws distributed in an array are respectively provided on the upper and lower sides of one of the cold conduction plates, and the locking screws pass through the side of the flow channel box and are connected to the other cold conduction plate through threads.

[0011] Furthermore, a disc spring assembly is sleeved on one end of the locking screw, and one end of the disc spring assembly is in contact with a side wall of one of the cold conduction plates.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Battery thermal management primarily aims to keep the battery pack operating within a suitable temperature range, thereby maintaining optimal operating conditions. Battery thermal management primarily includes cooling, heating, and temperature equalization. Cooling and heating primarily adjust for the potential impact of ambient temperature on the battery. Temperature equalization minimizes temperature variations within the battery pack, preventing rapid degradation caused by overheating of a single cell. This ensures optimal vehicle power output and input, maximum available energy, and the longest cycle life.

[0024] Please refer to Figure 1 - Figure 5 In order to maintain a sufficient thermal contact area for the corrosive liquid, the heat dissipation effect will be greatly improved, and at the same time, the heat conduction efficiency can be improved, which can significantly improve the cooling effect of the corrosive liquid. A chiller structure for corrosive liquid is provided, which consists of a flow channel box 10, a liquid inlet pipe 1, a liquid outlet pipe 2 and a cooling mechanism a. One end of the liquid inlet pipe 1 and the liquid outlet pipe 2 are fixedly connected to both sides of one end of the flow channel box 10 by welding, and the liquid inlet pipe 1 is located on the top of the liquid outlet pipe 2. The cooling mechanism a is arranged on the flow channel box 10 and is used to quickly cool the corrosive liquid. The internal cavity of the flow channel box 10 is arranged in a vortex shape and is arranged as a double-circulation flow channel. The flow channel is a double-sided cooling structure, which can increase the thermal contact area.

[0025] The cooling mechanism a is used to cool the corrosive liquid entering the flow channel box. Through the mutual cooperation of the water-cooling plate 8, the cold conduction plate 9 and the TEC refrigeration plate 14 on both sides of the flow channel box 10, the thermal contact area of ​​the corrosive liquid can be increased, and the heat conduction effect is also greatly enhanced, which is beneficial to improving the cooling effect of the corrosive liquid.

[0026] The cooling mechanism a includes a cold conduction plate 9 arranged on both sides of the flow channel box 10, and a water-cooling plate 8 arranged on one side of the two cold conduction plates 9 respectively. The cold conduction plate 9 is processed from a whole aluminum plate, and a circular corrosion-resistant and high thermal conductivity material is bonded to the aluminum plate. An internal flow channel is arranged on the inner side of the water-cooling plate 8, and the hot side of the TEC refrigeration plate 14 is cooled by the external circulating water. A plurality of screws 7 distributed in an array are arranged on one side of the water-cooling plate 8, and the screws 7 pass through the water-cooling plate 8 and are threadedly connected with the threaded holes opened on the surface of the cold conduction plate 9. A rectangular spring 6 is sleeved on the outer side of the end of the screw 7 away from the cold conduction plate 9, and one end of the rectangular spring 6 is in contact with one side of the water-cooling plate 8. A TEC refrigeration plate 14 is arranged between the cold conduction plate 9 and the water-cooling plate 8, and the water-cooling plate 8 and the TEC refrigeration plate 14 are squeezed and fixed on the cold conduction plate 9 by the rectangular spring 6. The pressure of the rectangular spring 6 is transmitted to the water-cooling plate 8, pressing the water-cooling plate 8 and the TEC refrigeration plate 14 tightly against the cold conduction plate 9.

[0027] The TEC refrigeration sheet 14 is composed of a series of P-type semiconductor materials and N-type semiconductor materials, which are arranged alternately to form a series of electron and hole conductive layers. When current passes through these conductive layers, heat is generated on one side of the P-type material, while heat is absorbed on the side of the N-type material, thereby achieving heat transfer. By controlling the direction of the current, the direction of this heat transfer can be changed, thereby achieving a cooling or heating effect. When the current direction is the same as the heat transfer direction, the TEC refrigeration sheet will produce a cooling effect on one side and a heating effect on the other side. When the current direction is opposite to the heat transfer direction, the TEC refrigeration sheet will produce a heating effect on one side and a cooling effect on the other side.

[0028] like Figure 1 and Figure 2 As shown, specifically, thermal insulation cotton 5 for storing the cold energy generated by external cold water is respectively provided at both ends of one side of the water-cooled plate 8. The thermal insulation cotton 5 is used to store the cold energy generated by the external cold water of the water-cooled plate 8. A cooling pipe 3 is movably connected to the bottom of one end of the water-cooled plate 8, and a heat-conducting disc 13 is detachably provided at one end of the cooling pipe 3. A temperature sensor 4 is fixedly installed on the liquid outlet pipe 2. The temperature sensor 4 is used to monitor the outlet temperature of the liquid from the liquid outlet pipe 2. When the outlet temperature of the liquid from the liquid outlet pipe 2 is abnormal, the staff can be reminded through an external alarm system to quickly make a corresponding response. An inclined inner flow pipe is provided at one end of the two water-cooled plates 8, and connecting pipes are fixedly provided at both ends of the inner flow pipe. The two connecting pipes are respectively connected to the upper and lower ends of the two water-cooled plates 8. The inner flow pipe ensures that the external cold water inside the two water-cooled plates 8 circulates with each other, further making the cold energy of the water-cooled plate 8 more evenly distributed.

[0029] Furthermore, a number of array-distributed locking screws 12 are respectively provided on the upper and lower sides of one of the cold conduction plates 9, and the locking screws 12 pass through the side of the flow channel box 10 and are connected to the other cold conduction plate 9 by a threaded connection. A disc spring group 11 is sleeved on one end of the locking screw 12, and one end of the disc spring group 11 contacts the side wall of one of the cold conduction plates 9. The disc spring group 11 cooperates with the locking screw 12 to press the left and right cold conduction plates 9 against the corrosive liquid flow channel box 10 in the middle, and the two cold conduction plates 9 are detachably arranged on both sides of the flow channel box 10, so that when the flow channel box 10 fails, it can be disassembled for maintenance.

[0030] The corrosive liquid enters the double-circulation flow channel inside the flow channel box 10 through the liquid inlet pipe 1, and the heat of the corrosive liquid is transferred to the cold conduction plates 9 on both sides thereof through the flow channel box 10. The heat is transferred to the TEC refrigeration plate 14 through the cold conduction plate 9. At the same time, the TEC refrigeration plate 14 is energized, so that the TEC refrigeration plate 14 forms a heating side and a cooling side. The cooling side contacts the cold conduction plate 9, and then exchanges the heat transferred from the flow channel box 10. At the same time, the heating side of the TEC refrigeration plate 14 contacts one side of the water-cooled plate 8, thereby cooling the heating side of the TEC refrigeration plate 14, so that the TEC refrigeration plate 14 maintains a stable working state, which is beneficial to improving the cooling effect of the corrosive liquid in the flow channel box 10.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
