Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically a heavy-duty truck energy storage heat exchange coordinated regulation mechanism. Background Technology

[0002] CN202323543552.0 discloses an integrated battery module for new energy vehicles. Through the set coolant channels, the heat dissipation performance of the entire battery module can be efficiently improved by circulating coolant during the operation of the battery module.

[0003] However, the aforementioned "coolant channel" is only set in the "inner cavity of the first frame", which leads to uneven heat dissipation effect on the battery module during heat dissipation, resulting in temperature differences inside the battery module, which may affect the life of the battery module. Moreover, using only one "coolant channel" also limits the improvement of heat dissipation effect. Therefore, this utility model provides a heavy truck energy storage heat exchange coordinated adjustment mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a heavy-duty truck energy storage heat exchange coordinated adjustment mechanism to solve the problem of limited improvement in heat dissipation effect mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heavy-duty truck energy storage heat exchange coordinated adjustment mechanism includes a carrier housing, multiple battery modules, a partition plate, two heat dissipation pipes, two fluid pipes, and two buffer frames. The partition plate is fixedly connected to the inside of the carrier housing to divide the inside of the carrier housing into two carrier areas for carrying the battery modules. Each carrier area is also provided with a heat dissipation pipe, a fluid pipe, and a buffer frame. The buffer frame is located on the outer wall of the battery module. The heat dissipation pipe is fixedly installed in the side wall formed by the buffer frame. Placement slots are opened on the side of the partition plate and the corresponding side wall of the carrier housing, and the fluid pipes are fixedly connected in the placement slots. The ends of the heat dissipation pipe and the fluid pipe extend to the outside of the carrier housing.

[0007] Preferably, the bearing housing includes a pair of first side plates and a pair of second side plates, which are spaced apart to form a rectangular frame; the two ends of the partition plate are fixedly connected between the pair of opposing first side plates, thereby dividing the interior of the rectangular frame into two bearing areas; a bottom plate is also fixedly connected to the bottom of the bearing housing.

[0008] Preferably, the fluid fitting includes a pair of first fluid pipes and a pair of second fluid pipes; the first fluid pipes are fixedly connected to a placement groove opened in the side wall of the first side plate in the bearing area; the pair of second fluid pipes are fixedly connected to the placement grooves opened in the partition plate and the side wall of the second side plate in the bearing area, respectively.

[0009] Preferably, the ends of the second fluid pipe located at the partition plate and the first fluid pipe located at the adjacent first side plate are not connected, and both extend outside the first side plate to serve as inlet and outlet respectively. The remaining first fluid pipes and second fluid pipes are connected in sequence and are internally connected. A pair of inlets and a pair of outlets in a pair of fluid pipe fittings are respectively fixedly connected to inlet pipes and outlet pipes.

[0010] Preferably, each buffer frame includes a first buffer frame and a second buffer frame; the first buffer frame is fixedly connected to a first side plate sidewall in the load-bearing area, and the second buffer frame is fixedly connected to a partition plate and a second side plate sidewall in the load-bearing area.

[0012] Preferably, the heat dissipation pipe also includes multiple vertical pipes, and multiple spaced vertical pipes are fixedly connected in both the first buffer frame and the second buffer frame. The vertical pipes are connected to the corresponding horizontal pipes. Multiple pairs of air holes are opened on each horizontal pipe and vertical pipe, and each pair of air holes is arranged radially along the horizontal pipe or vertical pipe.

[0014] Preferably, the heating assembly includes a protective cover and multiple rows of heating racks, which are equidistantly arranged inside the protective cover.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By incorporating heat dissipation pipes and fluid conduits, heat dissipation efficiency is significantly improved. A pair of first and second fluid conduits surround the battery module within the support area, ensuring more uniform heat dissipation, preventing internal temperature differences, and extending battery life. Horizontal and vertical pipes within the first and second buffer frames, also surrounding the battery module within the support area, provide air cooling. Combined with the fluid conduits, the selective use of either heat dissipation pipes or fluid conduits, based on the different heat dissipation requirements of the battery module, greatly enhances heat dissipation efficiency.

[0027] The load-bearing housing 1 includes a pair of first side plates 11 and a pair of second side plates 12, which are spaced apart and fixedly connected to each other to form a rectangular frame placement area. A partition plate 3 is located within the placement area and is fixedly connected at both ends to the middle of the pair of opposing first side plates 11, thereby dividing the rectangular frame into two load-bearing areas. A bottom plate is also fixedly connected to the bottom of the pair of first side plates 11 and the pair of second side plates 12.

[0028] The fluid fitting 5 includes a pair of first fluid pipes 51 and a pair of second fluid pipes 52.

The pair of second fluid pipes 52 are respectively fixedly connected to the placement grooves 13 opened on the side walls of the partition plate 3 and the second side plate 12 in the bearing area. Each first fluid pipe 51 and second fluid pipe 52 is arranged in a serpentine pattern. The ends of the second fluid pipe 52 located at the partition plate 3 and the first fluid pipe 51 located at the adjacent first side plate 11 are not connected and both extend outside the first side plate 11 to serve as the inlet 511 and the outlet 512 respectively (the inlet 511 and the outlet 512 are interchangeable). The remaining first fluid pipes 51 and second fluid pipes 52 are connected in sequence and are internally connected. The first fluid pipe 51 and the second fluid pipe 52 contain coolant for absorbing heat and cooling the battery module 2. A pair of inlets 511 in the pair of fluid pipes 5 are fixedly connected to inlet pipes 531, and a pair of outlets 512 in the pair of fluid pipes 5 are fixedly connected to outlet pipes 532. The inlet pipes 531 are connected to the pair of inlets 511, and the outlet pipes 532 are connected to the pair of outlets 512. A water pump (not shown in the figure) is fixedly connected between the inlet pipes 531 and the outlet pipes 532. The water pump makes the coolant in the pair of fluid pipes 5 circulate, so as to cool and dissipate heat from the battery module 2.

[0029] The buffer frame 6 includes a pair of first buffer frames 61 and a pair of second buffer frames 62; the pair of first buffer frames 61 are respectively fixedly connected to the side walls of a pair of first side plates 11 in the bearing area, and the pair of second buffer frames 62 are respectively fixedly connected to the side walls of the partition plate 3 and the second side plate 12 in the bearing area.

[0030] The heat dissipation pipe 4 includes multiple horizontal pipes 41 and multiple vertical pipes 42. A horizontal pipe 41 is fixedly connected within each first buffer frame 61 and second buffer frame 62. The multiple horizontal pipes 41 are connected sequentially and internally. The ends of the horizontal pipe 41 located at the partition plate 3 and the horizontal pipe 41 located at the adjacent first side plate 11 are not connected and extend outside the first side plate 11, serving as an air inlet 411 and an air outlet 412 respectively (the air inlet 411 and air outlet 412 are interchangeable). The air inlet 411 and air outlet 412 are used for blowing air into and drawing air into the horizontal pipe 41, respectively. Multiple vertical pipes 42 are fixedly connected within each first buffer frame 61 and second buffer frame 62, spaced apart, and connected to corresponding horizontal pipes 41. Multiple pairs of air holes are formed on each horizontal pipe 41 and vertical pipe 42, with each pair of air holes arranged radially along the horizontal pipe 41 or vertical pipe 42, allowing gas to be blown towards the battery module 2 and the fluid pipe 5.

[0031] A pair of air inlets 411 and a pair of air outlets 412 are respectively fixedly connected to an air inlet pipe 431 and an air outlet pipe 432; the air inlet pipe 431 and the air outlet pipe 432 are respectively connected to the pair of air inlets 411 and the pair of air outlets 412. An air pump 43 is fixedly connected to the air inlet pipe 431. The air pump 43 has the function of blowing and sucking air, so as to blow or suck air into the horizontal pipe 41 and the vertical pipe 42 through the air pump 43. A heating element 7 is also fixedly connected to the air outlet at the end of the air pump 43. This air outlet refers to the air outlet where the air pump 3 is not connected to the air inlet pipe 431.

[0032] The heating assembly 7 includes a protective cover 71 and multiple rows of heating racks 72, which are equidistantly arranged inside the protective cover 71. The heating racks 72 are connected to an external power source for heating, thereby raising the temperature of the gas at the heating racks 72. The heated gas is then pumped to the battery module 2 via the air pump 43 to preheat the battery module 2.

[0033] Working principle: When battery module 2 needs heat dissipation, the coolant in the first fluid pipe 51 and the second fluid pipe 52 is circulated by a water pump to perform liquid cooling of battery module 2. If liquid cooling cannot meet the cooling requirements, air pump 43 is activated to draw heat from the bearing area to the outside of the bearing housing 1 through horizontal pipe 41 and vertical pipe 42, thus working in conjunction with the fluid pipes 5 to achieve dual cooling. Air pump 43 can also be used alone to dissipate heat from battery module 2.

[0034] In low-temperature environments, preheating is required before the battery module 2 can operate to extend its lifespan. The heating frame 72 is powered on and heats the gas inside the protective cover 71. The air pump 43 is then activated, blowing the heated gas from the heating frame 72 through the horizontal pipe 41 and the vertical pipe 42 onto the battery module 2 to preheat it.
