[0002] At present, the energy storage performance of new energy batteries is getting higher and higher. During use, the high rate of charge and discharge will cause the battery temperature to rise too high, thus affecting its performance and life. If the temperature rise is not effectively handled, it may even cause thermal runaway and endanger the user's life. Therefore, it is usually necessary to do a good job of heat dissipation and cooling design in the battery box used to store new energy batteries to increase the service life of the battery module.

[0003] In the related art, a liquid cooling plate or liquid cooling box structure is usually set between the gaps between multiple modules of the battery box, and a cooling water heat exchange pipe is usually integrated inside it. It is connected to a water supply mechanism such as a cooling water tank in power terminals such as new energy vehicles, and heat is exchanged with the heated battery module through the flow of cooling water to achieve heat dissipation and cooling.

[0004] For example, announcement number CN216903112U discloses a temperature equalizing device and a temperature equalizing system for new energy battery modules, which belongs to the technical field of new energy equipment. The temperature equalizing device includes a temperature equalizing liquid cooling plate, a heat pipe structure and a TEC chip.

[0019] The present invention also discloses a temperature equalizing system for a new energy battery module, wherein a temperature sensor is fixedly installed on the side wall of the side frame, and the temperature sensor is also electrically connected to a temperature control switch.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) Through the coordination between the temperature-averaging shell, the arc-shaped heat exchange tube, the flexible tube, the straight connecting tube, the twisted tube, and the condenser tube, the arc-shaped heat exchange tube is inserted into the gap of the battery pack body, the contact area is greatly increased, and the heat exchange range is large. After the heat exchange, the heat of the arc-shaped heat exchange tube is transferred to the condenser tube. After the condenser tube is cooled again, the coolant circulates again to dissipate heat for the battery pack body. At the same time, when the liquid or gas in the tube expands and contracts, the twisted tube and the flexible tube deform at the same time to offset the expansion and contraction force, thereby reducing the damage of the arc-shaped heat exchange tube and increasing its service life. When it expands and contracts, the arc-shaped heat exchange tube changes inside the battery pack body, further ensuring the uniformity of the temperature of the battery pack body and increasing the service life of the device;

[0022] (2) When the temperature of the device is high, high pressure is likely to occur inside the device and inside the tube. The tube expands due to the high pressure, the internal pressure increases, the straight connecting tube and the flexible tube extend, and the arc-shaped heat exchange tube is squeezed to both sides, driving the sliding rod to move toward the air release block, lifting the air release block, causing the air hole to release air, releasing the internal pressure of the shell mechanism, preventing the internal part of the device from bulging due to high pressure, and achieving good protection effect;

[0023] (3) A liquid inlet is also provided at the upper end of the arc-shaped heat exchange tube, and a liquid inlet pipe is also provided on one side of the temperature-averaging shell. A push rod is fixedly installed at one end of the piston ring, and a limit ring is fixedly installed at one end of the push rod. The limit ring is slidably installed inside the straight connecting tube and is also provided at the lower end of the liquid inlet to block the liquid inlet. When the first magnetic attraction member, the second magnetic attraction member and the piston ring slide inside the straight connecting tube, the push rod and the limit ring slide together and detach from the liquid inlet. The liquid inside the temperature-averaging shell flows into the arc-shaped heat exchange tube through the liquid inlet pipe. Multiple push rods can slide separately to even out the local temperature, thereby increasing the flow rate of the arc-shaped heat exchange tube and further increasing the heat exchange effect.

[0024] (4) The operator sets the maximum temperature threshold on the temperature control switch. When the temperature detected by the temperature sensor exceeds the threshold set by the temperature control switch, the electromagnetic block is triggered to start. After the electromagnetic block is turned on, it repels the second magnetic element, causing the second magnetic element, the push rod, and the limit ring to slide together and detach from the liquid inlet. Multiple liquid inlets move together, further increasing the liquid circulation rate and greatly enhancing the heat exchange effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The present invention is further described below in conjunction with specific embodiments.

[0041] Example 1

[0042] like Figure 1 , Figure 4-Figure 11 As shown, a temperature equalizing device for a new energy battery module includes a shell mechanism 1, a support mechanism 2 is arranged inside the shell mechanism 1, a battery pack body 3 is arranged inside the support mechanism 2, the support mechanism 2 includes a fixed frame 21, the fixed frame 21 is provided with four groups, a first clamping groove 22 and a second clamping groove 23 are opened on the fixed frame 21, the battery pack body 3 is clamped and installed in the first clamping groove 22, the battery pack body 3 is assembled from a plurality of batteries, the battery pack body 3 is fixed in the shell mechanism 1 by the support mechanism 2, and has stability, wherein, under the action of the fixed frame 21, the outer periphery of the battery pack body 3 does not contact the inner wall of the shell mechanism 1, so as to ensure the air pressure balance and temperature uniformity inside the device.

[0043] A condensation mechanism 4 is provided on both sides of the battery pack body 3, and the condensation mechanism 4 includes a temperature-equalizing shell 41 that is snap-fitted to the upper end of the second snap-fitting groove 23. The temperature-equalizing shell 41 on both sides of the battery pack body 3 is a closed cavity, into which condensation liquid can be injected to dissipate heat and cool the battery pack body 3.

[0044] A temperature equalizing mechanism 5 is arranged on one side of the battery pack body 3, and the temperature equalizing mechanism 5 includes an arcuate heat exchange tube 51. The batteries and the arcuate heat exchange tube 51 are arranged alternately, and heat exchange and temperature uniformity can be achieved inside the battery pack body 3. The arcuate heat exchange tube 51 is an arched structure, and two adjacent arcuate heat exchange tubes 51 are located one above and one below each other, and the upper and lower ends of the battery can be respectively temperature-uniformed. The arcuate heat exchange tube 51 is an oblate structure, and has a larger contact surface with the battery, a large heat exchange range, and saves the space between adjacent batteries, resulting in a good use effect.

[0045] Flexible tubes 52 are installed on both sides of the arc-shaped heat exchange tube 51. The arc-shaped heat exchange tube 51 is connected to a straight connecting tube 53 through the flexible tube 52. The flexible tube 52 can be deformed so that the arc-shaped heat exchange tube 51 and the straight connecting tube 53 are rotatably connected. The straight connecting tube 53 is arranged in the middle of the battery pack body 3 and the temperature-equalizing shell 41. A torsion tube 54 is installed on one end of the straight connecting tube 53. A condenser tube 55 is commonly connected between two adjacent torsion tubes 54. The condenser tube 55 is arranged inside the temperature-equalizing shell 41. The head and tail of the arc-shaped heat exchange tube 51 are connected to the condenser tube 55 through the straight connecting tube 53 and the torsion tube 54. The two sides of the arc-shaped heat exchange tube 51 are also connected to the temperature-equalizing shell 41 to form a complete passage. If coolant is injected into the inner cavity of the temperature-equalizing shell 41, the liquid can flow through the straight arc-shaped heat exchange tube 51 to form a cycle, which continuously dissipates heat and equalizes the temperature for the battery pack body 3.

[0046] The torsion tube 54 is a flexible structure that can be deformed and bent. After the liquid enters the torsion tube 54, the flow direction of the liquid will also change. When the liquid flow rate is too fast, the torsion tube 54 will be squeezed and deformed, which can play a buffering role and prevent the arc heat exchange tube 51 from being damaged due to excessive water pressure. By setting the torsion tube 54, the uniformity of temperature and flow rate during the circulation of the coolant is guaranteed, and the uniform temperature effect is greatly enhanced.

[0047] A lap plate 511 is fixedly installed at the lower end of one side of the arc-shaped heat exchange tube 51, and the lap plate 511 is arranged at the lower end of the flexible tube 52. In the initial state, one side of the straight connecting tube 53 close to the flexible tube 52 is lap-mounted on the lap plate 511. The inside of the tube is a sealed environment, which is prone to thermal expansion and contraction. When the tube expands, the internal pressure increases, the torsion tube 54 is squeezed and deformed, and the length of the torsion tube 54 changes, that is, there is a pulling force at both ends of the straight connecting tube 53, and the flexible tube 52 is stretched, which plays a buffering role again. Similarly, when contraction occurs in the tube, the flexible tube 52 shortens adaptively, does not affect the shape of the arc-shaped heat exchange tube 51, and has a certain degree of safety.

[0048] During the shortening of the straight connecting tube 53 and the flexible tube 52, the height of the arc-shaped heat exchange tube 51 approaches the direction of the straight connecting tube 53. Conversely, during the extension of the straight connecting tube 53 and the flexible tube 52, the arc-shaped heat exchange tube 51 is squeezed to both sides and the height of the arc-shaped heat exchange tube 51 changes, that is, the place where heat is exchanged on the battery pack body 3 changes, which further increases the uniformity of heat exchange of the battery pack body 3.

[0049] Adjacent arc-shaped heat exchange tubes 51 are provided with flexible tubes 52 and twisted tubes 54. When the heat in one place inside the battery pack body 3 is high, the surrounding arc-shaped heat exchange tubes 51 adaptively deform to exchange heat, which can be adjusted individually and has a good use effect.

[0050] Through the coordination among the temperature-equalizing shell 41, the arcuate heat exchange tube 51, the flexible tube 52, the straight connecting tube 53, the torsion tube 54, and the condenser tube 55, the arcuate heat exchange tube 51 is inserted into the gap of the battery pack body 3, the contact area is greatly increased, and the heat exchange range is large. After the heat exchange, the heat of the arcuate heat exchange tube 51 is transferred to the condenser tube 55, and after being cooled again by the condenser tube 55, the coolant circulates again to dissipate heat for the battery pack body 3. At the same time, when the liquid or gas in the tube expands and contracts due to heat, the torsion tube 54 and the flexible tube 52 are deformed at the same time to offset the expansion and contraction force, thereby reducing the damage of the arcuate heat exchange tube 51 and increasing its service life. When it expands and contracts due to heat, the arcuate heat exchange tube 51 changes inside the battery pack body 3, further ensuring the uniformity of the temperature of the battery pack body 3 and increasing the service life of the device.

[0051] Example 2

[0052] like Figure 1-Figure 8As shown, the shell mechanism 1 includes a liquid cooling plate 11, and heat sinks 12 are fixedly installed on both sides of the upper end of the liquid cooling plate 11. A side frame 13 is provided at the upper end of the liquid cooling plate 11, and the heat sinks 12 are arranged on both sides of the side frame 13 to dissipate heat for the device. A heat insulating sheet 14 is fixedly installed on the upper end of the side frame 13 to reduce the external heat from entering the device. A top plate 15 is provided on the upper end of the heat insulating sheet 14, and an air hole 16 is provided on the upper end of the top plate 15. By providing the air hole 16, pressure relief and heat dissipation are performed for the device.

[0053] A vertical plate 24 is installed between two adjacent fixed frames 21. The vertical plate 24 is set in the middle of the two columns of battery pack bodies 3 to reinforce the device. A vertical groove 25 is opened in the middle of the vertical plate 24. Through holes 26 are opened at the upper and lower ends of the vertical plate 24. The through holes 26 are connected to the air holes 16, and the through holes 26 at the upper and lower ends are alternately distributed.

[0054] A deflation structure 27 is provided inside the through hole 26, and the deflation structure 27 includes a sliding rod 271 slidably installed in the through hole 26, a limit block 272 is fixedly installed on the periphery of the sliding rod 271, an elastic member 273 is installed between the limit block 272 and the vertical plate 24, and a deflation block 274 is fixedly installed on the upper end of the sliding rod 271. In the initial state, the deflation block 274 is blocked in the air hole 16.

[0055] When the temperature of the device is high, high pressure is likely to occur inside the device and inside the tube. The tube expands due to the high pressure, the internal pressure increases, the straight connecting tube 53 and the flexible tube 52 extend, and the arc-shaped heat exchange tube 51 is squeezed to both sides, driving the sliding rod 271 to move toward the air release block 274, lifting the air release block 274, causing the air hole 16 to release air, releasing the internal pressure of the shell mechanism 1, preventing the inside of the device from bulging due to high pressure, and having a good protective effect.

[0056] Example 3

[0057] like Figure 8-Figure 13 As shown, two temperature-equalizing shells 41 are respectively installed on both sides of the battery pack body 3, and a circulation pipe 42 is commonly connected between the two adjacent temperature-equalizing shells 41. A liquid pump is installed at one end of one of the circulation pipes 42. The liquid pump is arranged inside the temperature-equalizing shell 41. After the liquid pump is turned on, it can drive the circulation of the coolant. A bellows 43 is installed on the inner wall of the temperature-equalizing shell 41, and a torsion tube 54 is arranged inside the bellows 43. There is a closed chamber inside the bellows 43 and outside the torsion tube 54, and an inert gas is arranged inside the chamber. The inert gas can expand and contract with heat and cold, driving the bellows 43 to expand and contract. After the bellows 43 expands and contracts, the torsion tube 54 deforms adaptively.

[0058] The corrugated tube 43 is stretched after being heated, and squeezes the straight connecting tube 53 toward the arc-shaped heat exchange tube 51, further driving the arc-shaped heat exchange tube 51 to move up and down, thereby increasing the feasibility of the device.

[0059] A fixing ring 56 is fixedly installed on the outer periphery of the straight connecting pipe 53 , an extrusion rod 57 is slidably installed on one end of the fixing ring 56 , one end of the extrusion rod 57 is fixedly connected to the temperature-averaging housing 41 , and a first magnetic attraction member 58 is fixedly installed on one end of the extrusion rod 57 .

[0060] A second magnetic component 59 is magnetically installed inside the first magnetic component 58, and piston rings 591 are fixedly installed on both sides of the second magnetic component 59. The piston rings 591 surround the other three sides of the second magnetic component 59 that are not in contact with the first magnetic component 58. The second magnetic component 59 and the piston ring 591 are slidably installed inside the straight connecting tube 53.

[0061] Under the action of the fixing ring 56, the extrusion rod 57 and the first magnetic component 58, the bellows 43 is stretched after being heated, the position of the extrusion rod 57 remains unchanged, the first magnetic component 58 and the second magnetic component 59 are magnetically attracted together and slide inside the straight connecting tube 53. The first magnetic component 58 and the second magnetic component 59 are arranged at the water inlet end of the arc-shaped heat exchange tube 51. During the sliding process of the second magnetic component 59, the piston ring 591 on its outer periphery moves inside the straight connecting tube 53 to facilitate the promotion of liquid circulation.

[0062] A liquid inlet 512 is also provided at the upper end of the arc-shaped heat exchange tube 51, and a liquid inlet pipe 44 is also provided on one side of the temperature-averaging shell 41. A push rod 592 is fixedly installed at one end of the piston ring 591, and a limit ring 593 is fixedly installed at one end of the push rod 592. The limit ring 593 is slidably installed inside the straight connecting tube 53 and is also arranged at the lower end of the liquid inlet 512 to block the liquid inlet 512. When the first magnetic component 58, the second magnetic component 59 and the piston ring 591 slide inside the straight connecting tube 53, the push rod 592 and the limit ring 593 slide together and detach from the liquid inlet 512. The liquid inside the temperature-averaging shell 41 flows into the arc-shaped heat exchange tube 51 through the liquid inlet pipe 44. Multiple push rods 592 can slide individually to even out the local temperature, thereby increasing the flow rate of the arc-shaped heat exchange tube 51 and further increasing the heat exchange effect.

[0063] Example 4

[0064] like Figure 1 , Figure 8-Figure 14As shown, the present invention also discloses a temperature equalization system for a new energy battery module. A temperature sensor 17 is fixedly installed on the side wall of the side frame 13. The model of the temperature sensor 17 is DS18B21. The temperature sensor 17 is also electrically connected to a temperature control switch 6. An electromagnetic block 7 is installed between the straight connecting tube 53 and the torsion tube 54. The electromagnetic block 7 is electrically connected to the temperature control switch 6.

[0065] The operator sets the maximum temperature threshold on the temperature control switch 6. When the temperature detected by the temperature sensor 17 exceeds the threshold set by the temperature control switch 6, the electromagnetic block 7 is triggered to start. After the electromagnetic block 7 is turned on, it repels the second magnetic component 59, causing the second magnetic component 59, the push rod 592, and the limit ring 593 to slide together and detach from the liquid inlet 512. Multiple liquid inlets 512 move together, further increasing the liquid circulation rate and greatly enhancing the heat exchange effect.
