[0013] Attached Figure 3 The figure is a partial structural diagram of a heat dissipation assembly according to an embodiment of the utility model. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings.
[0015] As attached Figure 1-3 The temperature-controlled energy storage module comprises an energy storage unit body 1, a heat dissipation assembly 2 is arranged on the heat dissipation surface of the energy storage unit body 1; the heat dissipation assembly 2 comprises a plurality of heat dissipation units arranged in an array, adjacent heat dissipation units are arranged in parallel with each other, the heat dissipation units are arranged to slide against the heat dissipation surface, and the sliding direction is arranged along the arrangement direction of the heat dissipation units; the heat dissipation assembly 2 is provided with a sliding drive module 3 for driving the sliding of the heat dissipation unit; the energy storage unit body 1 is provided with a built-in temperature sensing module for sensing the temperature distribution on the heat dissipation surface, and the signal output end of the temperature sensing module is electrically connected to the signal receiving end of the sliding drive module 3 through a control module.
[0016] This solution detects the temperature distribution of the heat dissipation surface of the energy storage module through the arranged temperature sensors, mainly monitoring the distribution law in the arrangement direction of the heat dissipation units, and according to the change of temperature distribution, controls the sliding drive module to drive each heat dissipation unit to perform sliding adjustment, which can change the distribution density of multiple heat dissipation units on the heat dissipation surface. When the heat dissipation surface causes a local temperature rise due to heat dissipation difficulties, multiple heat dissipation units are gathered to the corresponding area through sliding adjustment. The heat dissipation unit is made of heat-conducting material. By increasing the number of heat-conducting parts in the area, the heat dissipation area is increased. The heat dissipation rate of the area can be accelerated with the external air cooling device to ensure the safety of the energy storage module. That is, this solution is an energy storage module based on temperature detection, control and adjustment of the heat dissipation components to achieve local heat dissipation efficiency, and has high safety.
[0017] The heat dissipation unit is provided with a heat sink 21 and an elastic unit 22, the heat sink 21 and the elastic unit 22 are arranged alternately, and both ends of the heat dissipation component 2 are set to the heat sink 21; the sliding drive module 3 is provided with two sliding blocks 31, and the two sliding blocks 31 are respectively connected to the two heat sinks 21 at the end and the power device; the sliding block 31 is slidably set in the guide groove, and the guide groove is arranged along the arrangement direction of the heat dissipation unit.
[0018] Among them, the heat sink and the elastic unit are both made of heat-conducting materials and can both have a heat dissipation effect. In particular, the elastic unit has a certain elastic reset ability compared to the heat sink. By alternately arranging the two heat dissipation units and controlling the end units, the multiple elastic units in the middle are compressed when the heat sinks at both ends are close to each other, thereby realizing the adjustment of the distribution position and distribution density of the heat dissipation units, and being able to ensure that the distance between the heat dissipation units remains balanced, that is, the distance between the units increases or decreases synchronously, thereby achieving uniform heat dissipation of the precise target area.
[0019] Preferably, the power device includes a screw sleeve 32 fixedly connected to the sliding block 31, the screw sleeve 32 is threadedly matched with a screw rod 33, the screw rod 33 is connected to the output end of the driving motor, the screw rod 33 and the guide groove are arranged in the same direction, and the screw rod 33 is axially limited. The motor drives the screw rod to rotate along its own axis, and due to its axial limit, the screw sleeve threadedly matched with it moves along its axial direction, thereby driving the connected sliding block to slide along the guide groove, thereby realizing the sliding adjustment of the end heat sink.
[0020] The heat dissipation surface is provided with a limited slide groove 11, the root of the heat dissipation unit is slidably matched with the limited slide groove 11, and the contact surfaces of adjacent heat dissipation units are connected by elastic heat insulation 4. Firstly, it can ensure that the sliding directions of each heat dissipation unit are on the same straight line, ensuring the stability of the adjustment process, and also avoiding direct contact between adjacent heat dissipation units, avoiding wear and tear caused by long-term adjustment, and extending the service life; and using heat insulation materials to avoid heat transfer between heat dissipation units, forcing the heat to diffuse outward along the heat dissipation unit, and improving the heat dissipation efficiency.
[0021] The thickness of the heat sink 21 at the end away from the energy storage unit body 1 is smaller than the thickness at the end close to the energy storage unit body 1. This is beneficial for heat transfer to the heat sink, reduces thermal resistance, and makes it easier for heat to diffuse into the air.
[0022] The elastic unit 22 is a conical bent plate, and its bent end is set away from the energy storage unit body 1. It uses the same material as the heat sink, and is set to be bent to make it elastic. After removing the extrusion constraints of the heat sinks at both ends, the spacing between the heat sinks can be restored to the original spacing through elastic reset, and the entire heat dissipation surface can be covered to meet the most basic heat dissipation needs. In general, the heat dissipation area of the elastic unit is larger, which also helps to speed up the heat dissipation efficiency. The elastic heat insulation member can use a rubber pad.
[0023] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
