Description

Technical Field

[0001] This utility model relates to the field of battery-related technology, and in particular to a cooling and dehumidifying device for batteries. Background Technology

[0002] A battery cooling and dehumidification device is a piece of equipment used in battery systems, whose main function is to control the temperature and humidity of the battery's operating environment. During the use of vehicle batteries, especially high-performance batteries such as lithium batteries, excessively high temperatures can lead to decreased battery performance, shortened lifespan, and even safety issues such as thermal runaway. When vehicles are driven in rainy weather, rainwater adheres to the battery, and excessive humidity can cause moisture to accumulate on battery electrodes and other components, affecting the battery's electrochemical performance and potentially causing short circuits and other malfunctions.

[0003] To ensure the normal operation of the battery, it is necessary to improve the cooling and dehumidification effect. Therefore, the structure of the battery casing needs to be improved. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of poor cooling and dehumidification effects in the existing technology and provides a battery cooling and dehumidification device with good cooling and dehumidification effects.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a battery cooling and dehumidification device, comprising:

[0006] Air guide ducts are provided on the outer side wall of the battery casing, and heat dissipation plates are connected between the air guide ducts;

[0007] The heat dissipation cavity is located at the lower end of the battery casing. A dehumidifying fan and several rotatable cooling fans are installed inside the heat dissipation cavity. The dehumidifying fan is located in the middle, and the cooling fans are arranged around the dehumidifying fan.

[0008] This cooling and dehumidification device includes air guide channels on two outer walls of the battery casing. These channels guide air through the casing, improving battery heat dissipation. A heat sink is mounted on each channel for heat dissipation. A heat dissipation cavity is located on the lower surface of the battery casing. A dehumidifying fan and a cooling fan are installed on the inner wall of this cavity. During vehicle operation, air enters the cavity through the air guide channels because the air guide channels and the heat dissipation cavity are connected. This causes the dehumidifying fan and the cooling fan to rotate under the airflow. The dehumidifying fan dehumidifies the battery, while the cooling fan dissipates heat. This structure improves the overall cooling and dehumidification effect.

[0009] Preferably, there is at least one air guide channel, and the inner wall of the air guide channel is inclined with the inclination direction facing the center of the bottom surface of the battery casing. There may be one or more air guide channels, and the inner wall of the air guide channel is an inclined surface with the inclination angle offset towards the center of the bottom surface of the battery casing. This allows air to enter from the air guide channel, be guided through its inclined inner wall surface to the bottom surface of the battery casing, and pass through the bottom surface of the battery casing, increasing the contact between the air and the bottom surface of the battery, thereby improving the cooling effect. Simultaneously, in rainy weather, the inclined inner wall of the air guide channel can guide rainwater on the battery downwards, facilitating drainage of the battery casing, improving the dehumidification effect of the battery casing, and preventing short circuits.

[0010] Preferably, an air inlet gap is provided between the heat sink and the bottom surface of the air guide duct. The installation of the heat sink can improve the heat dissipation effect of the battery. At the same time, the air inlet gap between the heat sink and the inner bottom surface of the air guide duct can improve the air or rainwater guiding effect of the air guide duct, thereby improving its cooling and dehumidification effects.

[0011] Preferably, the top of the heat dissipation cavity is provided with several guide channels, which are connected to the air guide channels. Specifically, the guide channels at the top of the heat dissipation cavity can divert air or rainwater flowing from the air guide channels, increasing the contact area between air and the battery casing, and simultaneously increasing the contact area between rainwater and the battery casing, thus facilitating improved cooling and dehumidification effects.

[0012] Preferably, a diversion plate is provided at the front end of the heat dissipation cavity, and the diversion plate is arranged at an angle. Specifically, the diversion plate, located at the front end of the heat dissipation cavity and angled towards the top center region of the cavity, directs air entering the cavity towards the top, facilitating its entry into the airflow channels at the top of the cavity. This increases the contact between the air and the battery casing, thereby improving heat dissipation. Simultaneously, the diversion plate reduces the size of the air inlet at the front end of the heat dissipation cavity, increasing the velocity of the incoming air and accelerating the evaporation of water from the battery casing, thus enhancing both heat dissipation and dehumidification.

[0013] Preferably, the tail end of the heat dissipation cavity is provided with several flow-disrupting plates, which are vertically placed bent plates arranged at equal intervals. Specifically, the presence of several flow-disrupting plates at the tail end of the heat dissipation cavity, where the bent plates are placed vertically on the end face of the cavity and are evenly spaced, allows the flow-disrupting plates to increase the airflow time within the heat dissipation cavity, thereby improving both heat dissipation and dehumidification effects.

[0014] Preferably, the dehumidifier fan is equipped with a mounting base, which is installed on the bottom surface of the heat dissipation cavity. A connecting shaft is located in the middle of the dehumidifier fan, and the connecting shaft is rotatably connected to the mounting base. Vertical fan blades are located on the side ends of the dehumidifier fan blades, and a dehumidifying scraper is located on the top of the dehumidifier fan, contacting the top surface of the heat dissipation cavity. Specifically, the mounting base is fixedly installed at the center of the bottom surface of the heat dissipation cavity. The connecting shaft in the middle of the dehumidifier fan is mounted on the mounting base, allowing the dehumidifier fan to rotate. The vertical fan blades on the side ends of the dehumidifier fan blades allow air entering the heat dissipation cavity to blow and rotate the dehumidifier fan, thereby agitating the air within the heat dissipation cavity, accelerating airflow, and improving heat dissipation. The dehumidifying scraper is located on the top of the dehumidifier fan blades, and this scraper contacts the top of the heat dissipation cavity. The rotation of the dehumidifier fan causes the scraper to remove water remaining on the top of the heat dissipation cavity, further improving the dehumidification effect.

[0015] Preferably, the cooling fan is equipped with a mounting base, which is installed on the bottom surface of the cooling cavity. A rotating shaft is installed in the middle of the cooling fan and is rotatably connected to the mounting base. The fan blades are flush with the top of the baffle. This structure, where the mounting base is installed on the bottom surface of the cooling cavity and the rotating shaft is mounted on the mounting base, allows the air entering the cooling cavity to drive the cooling fan to rotate, thereby improving its heat dissipation effect.

[0016] The beneficial effects of this utility model are as follows: the air guide groove can guide air into the heat dissipation cavity, exchange air at the lower end of the battery casing to achieve heat dissipation, and at the same time dehumidify the moisture on the battery casing, improving the heat dissipation and dehumidification effect; the dehumidifying fan and the heat dissipation fan are driven to rotate by the air entering the heat dissipation cavity, thereby improving the air exchange efficiency in the heat dissipation cavity and improving the heat dissipation and dehumidification effect; at the same time, the top of the dehumidifying fan is equipped with a dehumidifying scraper, which can drive the dehumidifying scraper to scrape off the adhering water on the top of the heat dissipation cavity when the dehumidifying fan rotates, thereby improving the evaporation of moisture and ensuring improved heat dissipation and dehumidification effect.

[0025] Example 1, such as Figure 1-4 As shown, a battery cooling and dehumidification device includes: an air guide trough 1, which is disposed on the outer side wall of the battery casing, and a heat dissipation plate 2 is connected between the air guide troughs 1; and a heat dissipation cavity 3, which is disposed at the lower end of the battery casing, and a rotatable dehumidifying fan 4 and several rotatable heat dissipation fans 5 are installed in the heat dissipation cavity 3, with the dehumidifying fan 4 located in the middle and the several heat dissipation fans 5 arranged around the dehumidifying fan 4.

[0026] The number of air guide channels 1 is at least one, and the inner wall of the air guide channel 1 is inclined and the inclined direction is towards the middle of the bottom surface of the battery case.

[0027] An air intake gap is provided between the heat sink 2 and the bottom surface of the air guide 1.

[0028] The top of the heat dissipation cavity 3 is provided with several flow guide grooves 6, which are connected to the air guide groove 1.

[0029] A flow guide plate 30 is provided at the front end of the heat dissipation cavity 3, and the flow guide plate 30 is arranged at an angle.

[0030] The heat dissipation cavity 3 is provided with several turbulence plates 31 at its tail end. The turbulence plates 31 are vertically placed bent plates and are arranged at equal intervals.

[0031] The dehumidifier fan 4 is provided with a mounting base 40, which is installed on the bottom surface of the heat dissipation cavity 3. A connecting shaft 41 is provided in the middle of the dehumidifier fan 4, which is rotatably connected to the mounting base 40. A vertical fan blade 42 is provided on the side end of the blade of the dehumidifier fan 4, and a dehumidifier scraper 43 is provided on the top of the dehumidifier fan 4, which is in contact with the top surface of the heat dissipation cavity 3.

[0032] The cooling fan 5 is provided with a fixing seat 50, which is installed on the bottom surface of the cooling cavity 3. A rotating shaft 51 is installed in the middle of the cooling fan 5, and the rotating shaft 51 is rotatably connected to the fixing seat 50. The blades of the cooling fan 5 are flush with the top of the baffle 31.

[0033] The working principle of this utility model is as follows: Figure 1-4 As shown, this cooling and dehumidification device includes air guide channels 1 on two outer side walls of the battery casing. The air guide channels 1 guide air through them, improving battery heat dissipation. A heat dissipation plate 2 is installed on each air guide channel 1, serving a heat dissipation function. A heat dissipation cavity 3 is located on the lower end face of the battery casing. A dehumidifying fan 4 and a cooling fan 5 are installed on the inner wall of the heat dissipation cavity 3. During vehicle operation, the air guide channels 1 and the heat dissipation cavity 3 are connected, allowing air to enter the cavity from the air guide channels 1. This causes the dehumidifying fan 4 and the cooling fan 5 to rotate under the influence of the airflow, thus dehumidifying the battery and dissipating heat. This structure improves the heat dissipation and dehumidification effect.

[0034] The number of air guide channels 1 is one or more. The inner wall of the air guide channel 1 is an inclined surface, and the inclination angle of the inclined surface is offset towards the center of the bottom surface of the battery case. This allows air to enter from the air guide channel 1 and be guided to the bottom surface of the battery case through its inclined inner wall surface, thus increasing the contact between the air and the bottom surface of the battery and thereby improving the cooling effect. At the same time, in rainy weather, the inclined inner wall of the air guide channel 1 can guide the rainwater on the battery downward, which facilitates the drainage of the battery case, improves the dehumidification effect of the battery case, and avoids short circuits.

[0035] The installation of heat sink 2 can improve the heat dissipation effect of the battery. At the same time, the air inlet gap between heat sink 2 and the inner bottom surface of air guide 1 can improve the air guide 1's air or rainwater guiding effect, thereby improving its cooling and dehumidification effect.

[0036] Several airflow channels 6 are provided on the top of the heat dissipation cavity 3. These airflow channels 6 can divert the air or rainwater flowing from the airflow channel 1, thereby increasing the contact area between the air and the battery casing, and also increasing the contact area between the rainwater and the battery casing, thus facilitating improved cooling and dehumidification effects.

[0037] A diversion plate 31 is provided at the front end of the heat dissipation cavity 3. The diversion plate 31 is inclined, with the inclination angle facing the top center area of ​​the heat dissipation cavity 3. The diversion plate 31 is designed to blow air into the top of the heat dissipation cavity 3 when it enters, so that it can be blown into the guide groove 6 provided at the top of the heat dissipation cavity 3, thereby improving the contact between the air and the battery casing and thus improving the heat dissipation effect. At the same time, the diversion plate 31 reduces the air inlet at the front end of the heat dissipation cavity 3, thereby increasing the speed of the incoming air and increasing the evaporation rate of water on the battery casing, thereby improving the heat dissipation and dehumidification effect of the battery casing.

[0038] Among them, several turbulence plates are provided at the tail end of the heat dissipation cavity 3. The turbulence plates are bent plates placed upright on the end face of the tail end of the heat dissipation cavity 3, and the several turbulence plates are arranged at equal intervals. The turbulence plates can play a role in turbulence. This structure can increase the flow time of air entering the heat dissipation cavity 3, thereby improving the heat dissipation and dehumidification effects.

[0039] The dehumidifier fan 4 is equipped with a mounting base 40, which is fixedly installed at the center of the bottom surface of the heat dissipation cavity 3. At the same time, the connecting shaft 41 in the middle of the dehumidifier fan 4 is installed on the mounting base 40, so that the dehumidifier fan 4 can rotate. Meanwhile, the side ends of the blades of the dehumidifier fan 4 are provided with vertical fan blades 42. The vertical fan blades 42 can cause the air entering the heat dissipation cavity 3 to blow the dehumidifier fan 4 to rotate, thereby agitating the cavity in the heat dissipation cavity 3, accelerating the air flow, and improving the heat dissipation effect. At the same time, the top of the blades of the dehumidifier fan 4 is provided with a dehumidifying scraper 43. The dehumidifying scraper 43 can contact the top of the heat dissipation cavity 3. When the dehumidifier fan 4 rotates, the dehumidifying scraper 43 scrapes away the water remaining on the top of the heat dissipation cavity 3, thereby improving its dehumidification effect.

[0040] The cooling fan 5 is mounted on the bottom surface of the cooling cavity 3 with a fixed base 50. The rotating shaft 51 in the middle of the cooling fan 5 is mounted on the fixed base 50 and is rotatably connected to the fixed base 50. This structure allows the air entering the cooling cavity 3 to blow the cooling fan 5 to rotate, thereby improving its heat dissipation effect.
