[0002] The battery pack in an electric forklift usually has many monomers connected in series, connected by copper wires, and protected and fixed by a shell (such as an iron box). Good heat dissipation can ensure the normal operation of the battery, extend the battery life, and improve safety. Therefore, in order to reduce the vehicle temperature, a heat dissipation device is generally added to the electric forklift to ensure that the entire system of the electric forklift is in an excellent working environment.

Among them, the cooling system is arranged inside the vehicle body, the space is compact, the cooling effect is poor, and the air duct is not smooth. In addition, there are many motors, electronic controls, and hydraulic components inside the vehicle body, which makes the layout of the cooling device not ideal and cannot give full play to the best cooling effect.

[0013] In a further solution, the heat sink and the sealing plate are fixedly connected via a transition support, but the present invention is not limited thereto.

[0014] In a further solution, the sliding part includes a hanging support and a guide rail, the hanging support is connected to the inner side of the cover body, the guide rail is arranged on the heat dissipation body, and the hanging support is slidably connected to the guide rail.

[0015] It is understandable that there are many ways to connect the suspension support and the guide rail, as long as the sliding between the two can be ensured.

[0018] Beneficial effects of the utility model:

[0033] This embodiment provides a retractable heat dissipation device, the structure of which can be referred to as Figure 1 and Figure 2 As shown in , the retractable heat dissipation device includes a cover body 1 and a heat dissipation body 2. The heat dissipation body 2 can be accommodated inside the cover body 1, and can be pushed out of the cover body 1. In this embodiment, one side of the cover body 1 is provided with an opening for realizing the pushing out or retracting action of the heat dissipation body 2. The heat dissipation body 2 is respectively provided with a sliding part 24 and a driving part 25, and the heat dissipation body 2 can complete the telescopic action of the cover body 1 through the cooperation of the sliding part 24 and the driving part 25.

[0034] Please combine Figure 3 The heat dissipation body 2 includes a radiator 21 and a sealing plate 22. The size of the sealing plate 22 can be designed according to the opening of the cover body 1, so that when the heat dissipation body 2 is retracted into the cover body 1, the sealing plate 22 can cover the opening of the cover body 1; in this embodiment, a plurality of heat dissipation holes are provided on the sealing plate 22 to further enhance the heat dissipation effect of the radiator 21. Furthermore, the radiator 21 and the sealing plate 22 are fixedly connected. In this embodiment, the radiator 21 and the sealing plate 22 are connected by a transition support 23. Please continue to refer to Figure 3 The radiator 21 is provided with an oil inlet and an oil outlet, and the oil inlet and the oil outlet are connected to oil pipes 211 and 212 respectively. In this embodiment, the oil pipes 211 and 212 are curved and have sufficient bending margins to ensure that the oil pipes 211 and 212 will not produce flat corners when the heat dissipation body 2 extends or retracts the cover body 1, so as to ensure that the oil used for heat dissipation can flow smoothly and ensure the heat dissipation effect.

[0035] Please continue reading Figure 3 , and combined with Figure 1 and Figure 2 In this embodiment, the sliding portion 24 and the driving portion 25 are respectively disposed on two opposite sides of the heat sink 21 , and the sliding portion 24 and the driving portion 25 are respectively fixed to the inner side surface of the cover body 1 .

[0036] The sliding part 24 includes a suspension support 241, a roller 242 and a guide rail 243. The structure of the suspension support 241 can be seen in Figure 4The suspension support 241 is fixedly connected to the inner side of the cover 1 , the guide rail 243 is fixedly connected to the radiator 21 , and the roller 242 is disposed on a side of the suspension support 241 away from the cover 1 , and the roller 242 is embedded in the guide rail 243 and rolls along the guide rail 243 .

[0037] The driving part 25 includes a push-out cylinder 251 and a connecting support 252. The push-out cylinder 251 is connected to the inner side of the cover body 1, and the connecting support 252 is fixedly connected to one side of the radiator 21.

[0039] During specific operation, different working modes can be realized in cooperation with external devices. The retractable heat dissipation device in this embodiment can be divided into a manual working mode and an automatic working mode. The two working modes are respectively introduced below.

[0040] Manual working mode: The solenoid valve is controlled by the switch to supply oil to the push-out cylinder 251, so that the push-out cylinder 251 works and pushes the radiator 21 out of the cover 1 by about 120 mm. The specific push-out stroke can be designed according to needs to ensure that the position reached by the sealing plate 22 does not exceed the width of the entire vehicle. When the radiator 21 needs to be retracted, the switch is pressed to retract the radiator 21 into the cover 1.

[0041] Automatic working mode: a temperature sensor is set on the oil pipe 212 connected to the oil outlet of the radiator 21 to monitor the temperature of the radiator 21 and set a corresponding temperature threshold. When the temperature exceeds the threshold, the oil supply of the ejection cylinder 251 is automatically controlled to push the radiator 21 out of the cover 1; and when the whole vehicle stops, the ejection cylinder 251 automatically supplies oil and retracts, and the radiator 21 is retracted into the cover 1.
