Description

Technical Field

[0001] The utility model belongs to the technical field of battery pack refrigeration, and in particular relates to a new energy battery pack refrigeration structure. Background Art

[0002] Battery packs generally refer to combined batteries, mainly referring to the processing and assembly of lithium battery packs, which combine battery cells, battery protection boards and battery connectors through the battery PACK process to form products required by customers. New energy (NE): also known as unconventional energy, refers to various forms of energy other than traditional energy, referring to energy that has just begun to be developed or is being actively researched and is yet to be promoted, such as solar energy, geothermal energy, wind energy, ocean energy, biomass energy and nuclear fusion energy.

[0003] The battery pack in the battery pack will generate heat during the charging and discharging process. If this heat cannot be dissipated in time, it will at least affect the use of the battery pack and shorten the life of the battery pack. At worst, safety accidents may occur, causing safety hazards. In order to solve the above problems, a new energy battery pack refrigeration structure is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a new energy battery pack cooling structure to solve the problem that the battery pack in the battery pack generates heat during the charging and discharging process. If the heat cannot be dissipated in time, it will at least affect the use of the battery pack and shorten the life of the battery pack. At worst, it may even cause a safety accident and cause a safety hazard.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a new energy battery pack refrigeration structure, comprising a mounting seat and a battery pack body, characterized in that: a temperature controller and a semiconductor refrigerator are fixedly installed on the bottom surface of the inner wall of the battery pack body, cooling plates are fixedly installed on both side surfaces of the inner wall of the battery pack body, a plurality of heat dissipation fins are fixedly installed on both side surfaces of the battery pack body, a heat dissipation seat is fixedly installed on the bottom surface of the inner wall of the mounting seat, a plurality of heat dissipation fans are fixedly installed on the upper surface of the heat dissipation seat, and a plurality of heat dissipation grooves are provided on the bottom surface of the inner wall of the mounting seat.

[0007] Preferably, sockets are fixedly installed on both side surfaces of the inner wall of the mounting seat, a first spring and an insert block are installed in the socket, the first spring is fixedly connected to the socket, a spring plate is fixedly connected to the upper end of the first spring, the insert block is fixedly connected to the battery pack body, a card slot is provided on one surface of the insert block, fixing seats are fixedly installed on both side surfaces of the mounting seat, a second spring is fixedly installed in the fixing seat, one end of the second spring is fixedly connected to a slider, a card block is fixedly connected to one surface of the slider, and the battery pack body is card-fitted with the mounting seat.

[0008] Preferably, the temperature controller is electrically connected to the semiconductor refrigerator.

[0009] Preferably, the position of the heat sink is adapted to the position of the battery pack body.

[0010] Preferably, one end of the card block is installed in the card slot, and the card block and the card slot are slidably matched.

[0011] Preferably, a slide groove is provided on the upper surface of the fixing seat, a pull rod is slidably connected in the slide groove, and one end of the pull rod is fixedly connected to the sliding block.

[0012] Preferably, the insert block and the spring plate are both slidably matched with the socket, and the slide block is slidably matched with the fixing seat.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model sets a thermostat, a semiconductor refrigerator, a cooling plate, a heat dissipation fan and a heat dissipation fin. The thermostat detects the temperature inside the battery pack body. When the temperature is too high, the thermostat sends an electrical signal to the semiconductor refrigerator to make it work. In the semiconductor refrigerator, P-type and N-type semiconductor materials are combined together to form a thermocouple pair. When direct current passes through these materials, the flow of electrons between the two materials will produce an energy difference, resulting in heat being absorbed (cooling) at one contact point and released (heating) at another contact point. The semiconductor refrigerator is usually composed of thermoelectric materials, a heat sink and a cooling plate. The thermoelectric effect is used to transfer heat. When current passes through the semiconductor element, heat is generated in its P-type and N-type regions. This part of the heat is dissipated by the heat sink, and the cooling plate absorbs this part of the heat, so that the temperature of the cooling plate is reduced. Since the heat generated by the semiconductor element is uneven, the temperature of the heat sink and the cooling plate will also be uneven, thereby generating a thermal difference and achieving a cooling effect. The heat dissipation fan can dissipate heat from the outside of the battery pack body, thereby improving the heat dissipation efficiency of the battery pack body and avoiding the battery pack body from having a short service life.

[0015] 2. The utility model sets a card-fitting fit between the battery pack body and the mounting seat, pulls the pull rod to both sides, and the pull rod drives the card block to move through the slider. When the card block is pulled out of the card slot, the first spring is no longer restricted by the card block, and the first spring resets, moving the spring plate upward regularly, further pushing the plug block out of the socket, so that the battery pack body can be quickly disassembled and the battery pack body can be easily inspected and repaired.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In the semiconductor refrigerator 11, the P-type and N-type semiconductor refrigerators are fixedly installed. Conductive materials are combined together to form a thermocouple pair. When direct current passes through these materials, the flow of electrons between the two materials will produce an energy difference, causing heat to be absorbed at one contact point (cooling) and released at another contact point (heating). The semiconductor refrigerator 11 is usually composed of thermoelectric materials, a heat sink and a cooling plate. The thermoelectric effect is used to transfer heat. When current passes through the semiconductor element, heat is generated in its P-type and N-type regions. This part of the heat is dissipated by the heat sink, and the cooling plate absorbs this part of the heat, so that the temperature of the cooling plate is reduced. Since the heat generated by the semiconductor element is uneven, the temperature of the heat sink and the cooling plate will also be uneven, thereby generating a thermal difference and achieving a cooling effect. In addition, the heat dissipation fan 8 can dissipate heat from the battery pack body 2 from the outside, thereby improving the heat dissipation efficiency of the battery pack body 2 and avoiding the battery pack body 2 from having a short service life.

[0028] Sockets 13 are fixedly installed on both sides of the inner wall of the mounting seat 1, and a first spring 16 and an insert block 14 are installed in the socket 13. The first spring 16 is fixedly connected to the socket 13, and a spring plate 17 is fixedly connected to the upper end of the first spring 16.

By setting the battery pack body 2 and the mounting seat 1 to be clamped and matched, the pull rod 6 is pulled to both sides, and the pull rod 6 drives the clamping block 20 to move through the slider 19. When the clamping block 20 is pulled out of the slot 15, the first spring 16 is no longer restricted by the clamping block 20, and the first spring 16 is reset, and the spring plate 17 is regularly upward, and the plug 14 is further pushed out of the socket 13, so that the battery pack body 2 can be quickly disassembled, and the battery pack body 2 is convenient for maintenance.

[0034] Example:

[0035] like Figure 1-Figure 4 As shown, a method of using a new energy battery pack refrigeration structure of the utility model is as follows: when using the utility model, the thermostat 10 detects the temperature inside the battery pack body 2. When the temperature is too high, the thermostat 10 sends an electrical signal to the semiconductor refrigerator 11 to make it work. In the semiconductor refrigerator 11, P-type and N-type semiconductor materials are combined together to form a thermocouple pair. When direct current passes through these materials, the flow of electrons between the two materials will produce an energy difference, causing heat to be absorbed at one contact point (cooling) and released at another contact point (heating). The semiconductor refrigerator 11 is usually composed of thermoelectric materials, heat sinks and cooling sheets, and uses the thermoelectric effect to transfer heat. When current passes through a semiconductor element, it will be in its P-type and N-type regions. Heat is generated, and this part of heat is dissipated by the radiator, while the cooling plate absorbs this part of heat, so that the temperature of the cooling plate is reduced. Since the heat generated by the semiconductor element is uneven, the temperature of the radiator and the cooling plate will also be uneven, thereby generating a thermal difference and achieving a cooling effect. In addition, the cooling fan 8 can dissipate heat from the outside of the battery pack body 2 to improve the heat dissipation efficiency of the battery pack body 2. The pull rod 6 is pulled to both sides, and the pull rod 6 drives the block 20 to move through the slider 19. When the block 20 is pulled out of the slot 15, the first spring 16 is no longer restricted by the block 20. The first spring 16 is reset, and the spring plate 17 is regularly upward, and the plug 14 is further pushed out of the socket 13, so that the battery pack body 2 can be quickly disassembled, and the battery pack body 2 is convenient for maintenance.
