Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to a heat dissipation device for a new energy vehicle battery. Background Art

[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including fuel cell vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. In new energy vehicles, the power battery pack is one of the main power sources. The power battery pack will generate a lot of heat during the charging and discharging process, causing a large temperature difference between each single cell, which can easily lead to a serious reduction in the electrochemical performance of the battery. Therefore, it is necessary to effectively dissipate heat from the power battery pack;

[0003] After searching, the applicant found that a Chinese patent disclosed "a heat dissipation device for new energy vehicle batteries", and its publication (announcement) number is "CN 209592265 U". This patent mainly realizes the dust removal function by utilizing natural wind, and can also dissipate heat when the car is parked, ensuring the long-term effective operation of the car battery. At the same time, with the help of cooling components, the water cooling function of the car battery is realized, which greatly improves the heat dissipation effect and accelerates the cooling speed. However, a large amount of dust will be absorbed and accumulated on the dustproof net. If it is not cleaned in time, the dust will block the dustproof net, resulting in a decrease in the filtering effect of the dustproof net. For this reason, we propose a heat dissipation device for new energy vehicle batteries. Utility Model Content

[0025] See also Figure 7 and Figure 8The external discharge mechanism includes a trapezoidal dust discharge groove 26 opened at the lower end of the heat dissipation box 2, a translation groove 22 is opened on the front side of the dust scraper plate 11, a sealing plate 23 is slidably connected inside the translation groove 22, the translation groove 22 penetrates the dust removal groove 21, a spring is fixedly connected between the sealing plate 23 and the inner wall of the translation groove 22, an ash drop opening 24 is opened at the upper end of the sealing plate 23, and the ash drop opening 24 penetrates the sealing plate 23, and the ash drop opening 24 cooperates with the dust removal groove 21;

[0026] In this embodiment, when the scraper plate 11 moves out from the interior of the trapezoidal ash discharge groove 26, the spring will push the sealing plate 23 to move and seal the dust removal groove 21. When the scraper plate 11 returns to the interior of the trapezoidal ash discharge groove 26, the inner wall of the trapezoidal ash discharge groove 26 will push the sealing plate 23 to move, thereby causing the sealing plate 23 to shrink toward the interior of the translation groove 22. At this time, the ash discharge port 24 will move to the interior of the dust removal groove 21, thereby opening the dust removal groove 21 and allowing the dust to be discharged to the outside.

Because the scraper plate 11 and the dust removal plate 15 will rotate in the opposite direction with the first dust removal shaft 10 and the second dust removal shaft 14 as the center, the dust on the dust filter 3 will be cleaned, and when the scraper plate 11 re-enters the interior of the trapezoidal dust discharge groove 26, it will push the dust discharge port 24 of the sealing plate 23 to overlap with the dust removal groove 21.

[0031] During use, when the fan shaft 4 rotates, it can drive the reciprocating screw 6 to rotate, thereby utilizing the rotation of the reciprocating screw 6 to drive the vibration plate 7 to move, so that the vibration plate 7 translates left and right inside the vibration slide groove 13, thereby forming a vibration effect, and shaking off the dust on the dust filter net 3. In this way, the dust on the dust filter net 3 can be shaken off in time, thereby further increasing the filtering effect of the dust filter net 3.

[0032] Working principle:

[0033] The first step is that when the heat dissipation device body 1 is working, the servo motor is started and the transmission shaft 17 and the power shaft 18 are driven to rotate by the belt connection group 19. At this time, the arc gear 20 and the half gear 25 drive the connecting gear 12 and the connecting gear 16 to rotate, thereby mobilizing the rotation of the first dust removal shaft 10, the second dust removal shaft 14, the scraper plate 11 and the dust removal plate 15. When the rotation reaches the set angle, the arc gear 20 and the half gear 25 will lose the meshing with the connecting gear 12 and the connecting gear 16. At this time, due to gravity, Because the dust scraper plate 11 and the dust removal plate 15 will rotate in the opposite direction with the first dust removal shaft 10 and the second dust removal shaft 14 as the center, the dust on the dust filter 3 is cleaned, and when the dust scraper plate 11 re-enters the interior of the trapezoidal dust discharge groove 26, it will push the dust drop opening 24 of the sealing plate 23 to coincide with the dust removal groove 21, and at this time, the dust in the dust scraper plate 11 will be discharged to the outside of the heat dissipation box 2 through the dust drop opening 24, so that the dust accumulated on the dust filter 3 can be processed, the service life of the dust filter 3 is increased, and the filtering effect is improved;

[0034] The second step is that when the fan shaft 4 rotates, it can drive the reciprocating screw 6 to rotate, thereby utilizing the rotation of the reciprocating screw 6 to drive the vibration plate 7 to move, so that the vibration plate 7 translates left and right inside the vibration slide groove 13, thereby forming a vibration effect, and shaking off the dust on the dust filter 3. In this way, the dust on the dust filter 3 can be shaken off in time, thereby further increasing the filtering effect of the dust filter 3.
