[0002] In most car models, the battery is located in the engine compartment. High temperatures in the engine compartment during summer can directly affect the battery's internal structure. When the ambient temperature exceeds 45°C, the chemical balance within the battery is significantly disrupted, leading to side reactions. Furthermore, charging in high-temperature environments can cause battery performance degradation, thus shortening battery life, especially for batteries with low electrolyte levels. Current solutions typically involve cooling the battery through the vehicle's air conditioning or using fans for heat dissipation, but these methods require electricity and consume significant amounts of energy, increasing the burden on the battery.

Specific embodiments
[0030] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0031] An embodiment of the present utility model provides a battery, which is installed in the engine compartment. As Figure 1 shown, the battery includes a battery body 100 and a battery passive cooling device 200. Among them, the battery body 100 is generally in the shape of a cuboid, and the cooling device 200 includes a base 210, a coolant carrier 220, and a heat dissipation hole main body 230.
[0032] As Figures 1-3 shown, the base 210 is generally in the shape of a cuboid. An installation position 211 is provided at approximately the middle position on the upper surface of the base 210. The installation position 211 is generally rectangular to fit the battery body 100, and the installation position 211 is used to install the battery body 100. Among them, for the way of installing the battery body 100 in the installation position 211,示例性的, the battery body 100 can be integrally formed with the base 210, the battery body 100 can also be fixed in the installation position 211 through fixing components such as screws, and the battery body 100 can also be fixed in the installation position 211 by adhesive means.
[0033] As Figures 1-3 shown, the base 210 is provided with a first installation groove 212. The first installation groove 212 is formed by recessing downward from the upper surface of the base 210. The first installation groove 212 is located outside the installation position 211, and the first installation groove 212 forms a "return" shape around the four sides of the installation position 211.
[0034] As Figure 1As shown, the coolant carrier 200 is made of a porous absorbent material, such as a sponge or fabric. The coolant carrier 200 is installed in the first mounting groove 212 and extends from the first mounting groove 212 in a direction away from the upper surface of the base 210. The coolant carrier 200 extending in this direction can surround the battery body 100. Because the material of the coolant carrier 200 is easily compressed, in order to firmly fix the coolant carrier 200 in the first mounting groove 212, the thickness of the coolant carrier 200 is greater than the width of the groove opening of the first mounting groove 212. After being compressed, the coolant carrier 200 is installed in the first mounting groove 212, thereby firmly fixing the coolant carrier 200 in the first mounting groove 212. Due to its water absorption, the coolant carrier 200 can absorb liquid coolant (such as water, ethylene glycol coolant, organic acid salt type coolant, etc.), thus the coolant carrier 200 is used to carry coolant. When the coolant in the coolant carrier 200 evaporates, it absorbs heat from the surrounding area of the coolant carrier 200, thereby absorbing heat from the battery body 100 near the coolant carrier 200, thereby reducing the temperature of the battery body 100, so as to use the heat absorption of coolant evaporation to cool the battery body.
[0035] In one alternative implementation, such as Figure 1 and Figure 3As shown, the base 210 includes a receiving cavity 213 located within the base 210. The receiving cavity 213 communicates with at least a portion of the first mounting groove 212. For example, a portion of the first mounting groove 212 communicates with the receiving cavity 213, and the portion of the first mounting groove 212 not communicating with the receiving cavity 213 serves as a connecting structure to connect the mounting position 211 and the base 210. Alternatively, the entire first mounting groove 212 may communicate with the receiving cavity 213, but in this case, the mounting position 211 requires an additional connecting structure to connect the mounting position 211 and the base 210. For instance, the side of the mounting position 211 facing away from the upper surface of the base 210 may be fixedly connected to the bottom of the receiving cavity 213 of the base 210 via a fixing post. The receiving cavity 213 is used to receive a portion of the coolant and coolant carrier 220, i.e., a portion of the coolant carrier 220 is contained within the first mounting groove 212. Extending into the receiving cavity 213, the portion of the coolant carrier 220 extending into the receiving cavity 213 can absorb the coolant within the receiving cavity 213, thus reducing coolant sloshing when the base 210 shakes. Furthermore, the portion of the coolant carrier 220 extending into the receiving cavity 213 can automatically draw in coolant through capillary action and deliver it to the portion of the coolant carrier 220 extending away from the upper surface of the base 210, where it is stored, thereby replenishing the evaporated coolant. Additionally, the thickness of the coolant carrier 200 is greater than the width of the opening of the first mounting groove 212, and the coolant carrier 200 is compressed within the opening of the first mounting groove 212, thereby increasing the sealing between the coolant carrier 200 and the opening of the first mounting groove 212, preventing coolant leakage from the receiving cavity 213 through the opening of the first mounting groove 212.
[0036] In one alternative implementation, such as Figure 2 and Figure 6 As shown, the base 210 includes an injection section 214 and a cover section 215. The injection section 214 is generally a hollow cylinder and is located outside the first mounting groove 212. The injection section 214 communicates with the receiving cavity 213 and is used to inject coolant. That is, the user can inject coolant into the receiving cavity 213 through the injection section 214 to replenish the coolant in the receiving cavity 213 and prevent the coolant in the receiving cavity 213 from running out. The cover section 215 is used to cover the injection section 214. For example, the injection section 214... 4. The outer circumference has an external thread, and the inner circumference of the cover 215 has an internal thread. The cover 215 is screwed onto the injection part 214 through the mating relationship between the internal and external threads to seal the injection part 214 and prevent the coolant in the receiving cavity 213 from spilling out of the injection part 214. In addition, the cover 215 can also be connected to the injection part 214 through a connecting structure, so that when the cover 215 is unscrewed from the injection part 214, the cover 215 can also be suspended on the injection part 214 to prevent the cover 215 from falling off when it is unscrewed from the injection part 214.
[0037] In an alternative embodiment, as Figures 1-3 shown, the base 210 is provided with a second mounting groove 216, which is formed by recessing downward from the upper surface of the base 210. The second mounting groove 216 is not communicated with the accommodating cavity 213. The second mounting groove 216 is located outside the first mounting groove 212 and also inside the injection portion 214. The second mounting groove 216 forms a "hui" character shape around the periphery of the first mounting groove 212 and has a certain distance from the first mounting groove 212.
[0038] As Figure 1 and Figures 4-6 shown, the heat dissipation hole body 230 is generally in the shape of a cuboid penetrating up and down. The heat dissipation hole body 230 is installed in the second mounting groove 216. In order to firmly fix the heat dissipation hole body 230 in the second mounting groove 216, the thickness of the part of the heat dissipation hole body 230 installed in the second mounting groove 216 can be greater than the notch width of the second mounting groove 216, so that an interference fit is formed between the heat dissipation hole body 230 and the second mounting groove 216. The heat dissipation hole body 230 can protect the internal coolant carrier 220 and the battery body 100. The heat dissipation hole body 230 includes a plurality of heat dissipation hole parts 231, and the plurality of heat dissipation hole parts 231 are uniformly arranged on the peripheral surface of the heat dissipation hole body 230. The plurality of heat dissipation hole parts 231 all face the heat dissipation hole body 230 and the battery body 100 from the outside. The air in the engine compartment can enter the inside of the heat dissipation hole body 230 through the plurality of heat dissipation hole parts 231 to dissipate heat from the coolant carrier 220 and the battery body 100. In addition, the air entering through the plurality of heat dissipation hole parts 231 can also accelerate the evaporation of the coolant on the coolant carrier 220, thereby further cooling the battery body 100.
[0039] In an alternative embodiment, as Figure 1 and Figures 5-6 shown, the aperture diameter of the heat dissipation hole part 231 gradually decreases along the direction towards the heat dissipation hole body 230 and the battery body 100, that is, the aperture diameter of the part of the heat dissipation hole part 231 facing the outside is large, and the aperture diameter of the part of the heat dissipation hole part 231 facing the heat dissipation hole body 230 and the battery body 100 is small. The air in the engine compartment enters through the part with a large aperture diameter of the heat dissipation hole part 231. Due to the gradually decreasing aperture diameter of the heat dissipation hole part 231, the air entering the heat dissipation hole part 231 will accelerate in flow rate due to the Venturi effect. The accelerated air flow finally blows from the part with a small aperture diameter of the heat dissipation hole part 231 towards the heat dissipation hole body 230 and the battery body 100. This process is equivalent to forming a fan without power. When the accelerated air flow blows towards the heat dissipation hole body 230, it can further accelerate the evaporation of the coolant on the coolant carrier 220 and dissipate heat from the battery body 100, thereby further cooling the battery body 100.
[0040] In one alternative implementation, such as Figure 1 and Figure 5 As shown, the heat dissipation hole body 230 includes a third mounting groove 232. The third mounting groove 232 is a certain distance away from the base 210, and the third mounting groove 232 is located above the first mounting groove 212 and opposite to the first mounting groove 212. The coolant carrier 220 extends from the first mounting groove 212 to the third mounting groove 232. The third mounting groove 232 is used to fix the coolant carrier 220 and straighten the coolant carrier 220. Correspondingly, in order to firmly fix the coolant carrier 200 in the third mounting groove 232, the thickness of the coolant carrier 200 is greater than the width of the groove opening of the third mounting groove 232. That is, the coolant carrier 200 is compressed and installed in the third mounting groove 232, so that the coolant carrier 200 can be firmly fixed in the third mounting groove 232.
[0041] In this embodiment, the battery body 100 is mounted on the base 210, and the coolant is carried by the coolant carrier 220 mounted on the base 210. The coolant absorbs heat through evaporation and dissipates heat from the battery body 100. Thus, through structural design, cooling can be achieved without consuming electricity, relying solely on natural wind. The coolant carrier 220 is a water-absorbing material that can absorb coolant without power. The structural design of the heat dissipation hole 231 enables accelerated airflow without power. The battery components are designed to be separate, facilitating the installation and maintenance of each component.
[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
