It is understood that the elastic member 2 in the present disclosure has various embodiments, for example, the elastic member 2 may be provided as any one of a spring, a spring sheet, an elastic ring, and an elastic column, and the present disclosure is not limited to the specific structure of the elastic member 2.

The present disclosure does not limit the number of the elastic members 2, for example, in an exemplary embodiment of the present disclosure, as shown in fig. 1, the first and second heat dissipation members 3 and 4 of the present disclosure are respectively movably mounted on the mounting rod 1 in the axial direction of the mounting rod 1; the number of the elastic elements 2 is two, one end of one of the two elastic elements 2 is connected to the mounting rod 1, and the other end of the one of the two elastic elements 2 is connected to the first heat dissipation element 3 and is used for providing elastic force for moving the first heat dissipation element 3 towards the second heat dissipation element 4; one end of the other of the two elastic members 2 is connected to the mounting rod 1, and the other end is connected to the second heat radiating member 4, for providing an elastic force to move the second heat radiating member 4 toward the first heat radiating member 3.

Thus, the two elastic elements 2 are respectively matched with the first heat dissipation element 3 and the second heat dissipation element 4, and can respectively provide elastic forces for the first heat dissipation element 3 and the second heat dissipation element 4 to approach each other, which is not only beneficial to improving the approaching speed of the first heat dissipation element 3 and the second heat dissipation element 4, but also beneficial to improving the working efficiency of the whole heat dissipation structure 100, and the first heat dissipation element 3 and the second heat dissipation element 4 can reach clamping positions more quickly; in addition, the reliability of the whole heat dissipation structure 100 is improved, and the problem that the first heat dissipation member 3 or the second heat dissipation member 4 cannot reach the clamping position due to the fact that a certain elastic member 2 cannot work is avoided.

In another embodiment of the present disclosure, the number of the elastic member 2 may be provided as one, and one end of the elastic member 2 is connected to the mounting rod 1 and the other end is connected to the first heat dissipation member 3 or the second heat dissipation member 4 for providing an elastic force to move one of the first heat dissipation member 3 and the second heat dissipation member 4 toward the other. Thus, on the basis of ensuring the heat dissipation effect, the structure of the whole heat dissipation structure 100 is simpler, and the structure cost and the maintenance difficulty are also reduced.

The present disclosure has no limitation on the mounting of the first and second heat dissipation members 3 and 4 with embodiments. Optionally, in an exemplary embodiment of the present disclosure, as shown in fig. 1 to 4, the heat dissipation structure 100 of the present disclosure may further include at least one connection rod 5, one end of the connection rod 5 is connected to the first heat dissipation element 3 and/or the second heat dissipation element 4, the other end of the connection rod 5 is provided with a first through hole 51, and the mounting rod 1 is inserted into the first through hole 51. The mounting mode is simple in structure, and on the basis of realizing stable mounting of the first heat dissipation element 3 and the second heat dissipation element 4, the first heat dissipation element 3 and/or the second heat dissipation element 4 can move smoothly; moreover, by providing the connecting rod 5 and forming the first through hole 51 in the connecting rod 5, not only the moving directions of the first heat sink 3 and the second heat sink 4 can be guided, but also the first heat sink 3 and/or the second heat sink 4 can be moved more stably in the relative movement process. In addition, the first heat dissipation element 3 and/or the second heat dissipation element 4 form a stable connection relationship with the mounting rod 1 through the connection rod 5, which is also beneficial to improving the integrity and reliability of the whole heat dissipation structure 100.

In another embodiment of the present disclosure, the heat dissipation structure 100 of the present disclosure may further include a hooking ring or a hooking hook, each of which includes a hooking section and a connecting section connected to each other, the connecting section being connected to the first heat dissipation element 3 and/or the second heat dissipation element 4, and the hooking section being used for hooking to the mounting rod 1. In this way, it is also possible to achieve that the first heat sink 3 and/or the second heat sink 4, on the basis of a stable mounting, can also be moved relative to each other to reach the clamping position.

The motion control between the first and second heat dissipation elements 3 and 4 of the present disclosure has various embodiments, for example, in an exemplary embodiment of the present disclosure, as shown in fig. 1 to 4, the heat dissipation structure 100 of the present disclosure may further include a driving mechanism 6 for driving the first and second heat dissipation elements 3 and 4 away from each other. The driving mechanism 6 comprises a driving rod 61 and two driving blocks 62, the driving rod 61 is arranged between the first heat sink 3 and the second heat sink 4, two ends of the driving rod 61 are respectively connected with first ends 621 of the two driving blocks 62, a second end 622 of the driving block 62 is used for abutting against the connecting rod 5, the second end 622 is formed with a contact surface 6221 abutting against the outer peripheral surface of the connecting rod 5, the contact surface 6221 is shaped and configured to drive the first heat sink 3 or the second heat sink 4 to move towards a direction away from each other when the driving rod 61 moves along a first direction, and the heat dissipation structure 100 can reach a clamping position when the driving rod 61 moves along a second direction; wherein the first direction is opposite to the second direction and is perpendicular to the axial direction of the mounting rod 1.

In this manner, the distance between the first heat dissipating member 3 and the second heat dissipating member 4 may be controlled by the driving mechanism 6, when the driving mechanism 6 moves in the first direction, the first heat dissipating member 3 and the second heat dissipating member 4 are away from each other so as to place the battery 300 between the first heat dissipating member 3 and the second heat dissipating member 4, and when the driving mechanism 6 moves in the second direction, the first heat dissipating member 3 and/or the second heat dissipating member 4 approach each other by the elastic force of the elastic member 2 until returning to the clamping position.

Here, the present disclosure does not limit the specific structure of the driving block 62, for example, in an exemplary embodiment of the present disclosure, as shown in fig. 3, the driving block 62 of the present disclosure may be formed in a triangular column shape, and the contact surface 6221 is configured as an inclined surface. Thus, when the driving rod 61 moves in the first direction, the driving rod 61 drives the driving block 62 to move in the first direction, and since the contact surface 6221 is configured as an inclined surface, the driving block 62 pushes the connecting rods 5 of the first heat sink 3 and the second heat sink 4 to move in the axial direction of the mounting rod 1, so that the first heat sink 3 and the second heat sink 4 are far away from each other, so as to put the battery 300 between the first heat sink 3 and the second heat sink 4. When the driving rod 61 moves in the second direction, the first heat dissipation member 3 and/or the second heat dissipation member 4 approach each other by the elastic force of the elastic member 2 until returning to the clamping position.

In another embodiment, the drive block 62 may be configured as a pentagonal cylinder, and the contact surface 6221 as a slanted surface, also enabling the control of the spacing between the first and second heat dissipation members 3, 4 by the drive mechanism 6. In yet another embodiment of the present disclosure, the driving block 62 may be configured as a cam, and the contact surface 6221 is configured as a slope or an arc surface, which also enables the control of the distance between the first heat dissipation member 3 and the second heat dissipation member 4 by the driving mechanism 6.

The movement of the driving rod 61 may have a plurality of control modes, for example, a manual control mode may be adopted, that is, the driving rod 61 is manually controlled to move in the first direction or the second direction. It is also possible to use a linear driving means (e.g., a hydraulic cylinder, a pneumatic cylinder, a linear motor, etc.) having a thrust shaft connected to the driving rod 61 and controlling the driving rod 61 to move in the first direction or the second direction.

In the manner of manually controlling the driving rod 61, for convenience of operation, in an exemplary embodiment of the present disclosure, as shown in fig. 2, the heat dissipation structure 100 of the present disclosure may further include an operating rod 8, one end of the operating rod 8 is hinged to the driving rod 61, a second through hole 81 with an oblong hole is formed in the operating rod 8, and the operating rod 8 is rotatably sleeved on the mounting rod 1 through the second through hole 81. In this way, the movement of the driving rod 61, and therefore the driving rod 61, can be controlled by the movement of the operating lever, specifically, the movement direction of the driving rod 61 is realized by controlling the rotation direction of the operating lever, and the second through hole 81 of the oblong hole can be used for the mounting rod 1 to move therein,

in addition, the operating rod 8 of the present disclosure can also be formed into a lever structure (will), which is more labor-saving and more convenient to operate.

It is understood that the first and second heat dissipation elements 3 and 4 of the present disclosure may also employ other motion control means. For example, the positions of the first and second heat dissipation elements 3 and 4 are manually controlled, and when the battery 300 needs to be cooled, the distance between the first and second heat dissipation elements 3 and 4 is manually enlarged, the battery 300 is placed between the first and second heat dissipation elements 3 and 4, and then the first and/or second heat dissipation elements 3 and 4 are released, so that the first and second heat dissipation elements 3 and 4 are in the clamping position. Or a linear driving device (e.g., a hydraulic cylinder, a pneumatic cylinder, a linear motor, etc.), the positions of the first and second heat sinks 3 and 4 are controlled by the linear driving device, when the battery 300 needs to be cooled, the first and/or second heat sinks 3 and 4 are controlled by the linear driving device to be away from each other, the battery 300 is placed between the first and second heat sinks 3 and 4, and then the first and/or second heat sinks 3 and 4 are released, so that the first and second heat sinks 3 and 4 are in the clamping position.

In order to reduce the friction between the driving block 62 and the connecting rod 5, in an exemplary embodiment of the present disclosure, as shown in fig. 3, the heat dissipation structure 100 may further include at least one sliding ring 7, the sliding ring 7 is formed in a ring-shaped structure and rotatably sleeved on the connecting rod 5, and an outer circumferential surface of the sliding ring 7 is configured to abut against the contact surface 6221. Thus, when the driving block 62 moves along the first direction or the second direction, the slip ring 7 abuts against the contact surface 6221 of the driving block 62, and the slip ring 7 rotates while moving along the axial direction of the mounting rod 1, so that the friction between the driving block 62 and the connecting rod 5 can be effectively reduced, the wear of the driving block 62 and the connecting rod 5 is reduced, and the service life of the driving block 62 and the connecting rod 5 is prolonged.

In another embodiment of the present disclosure, the slip ring 7 may be formed as a bearing, the bearing comprising an inner ring, a rolling body and an outer ring, the inner ring being sleeved on the connecting rod 5, the rolling body being arranged between the inner ring and the outer ring, an outer surface of the outer ring being adapted to abut against the contact surface 6221. Therefore, the friction between the driving block 62 and the connecting rod 5 can be effectively reduced, so that the abrasion of the driving block 62 and the connecting rod 5 is weakened, and the service life of the driving block 62 and the service life of the connecting rod 5 are prolonged.

The electronic assembly that utilizes this principle is called a semiconductor refrigerator 9, also called a thermoelectric refrigerator or a thermo-cooler. Heating or cooling with high response speed can be controlled by switching the direction of the current of the semiconductor refrigerator 9. The semiconductor refrigerator 9 has the characteristics of no noise, no vibration, no need of refrigerant, small volume, light weight and the like, and has the advantages of reliable work, simple and convenient operation and easy cold quantity regulation. Wherein, when battery 300 needs the heat dissipation, flexible heat conduction layer 97 is the cold junction of semiconductor cooler 9 for absorb the heat of battery 300, and, flexible heat conduction layer 97 can have slight deformation, with the surface of laminating battery 300 for semiconductor cooler 9 has bigger contact surface 6221 product with the casing of battery 300, and then just can make heat conduction efficiency better, and the radiating efficiency is higher.

In addition, a heat conducting interface material can be coated between heat dissipation layer 91 (the hot end of semiconductor cooler 9) and first ceramic sheet layer 92, so that the thermal resistance between first ceramic sheet layer 92 and heat dissipation layer 91 is smaller, and the heat of semiconductor cooler 9 can be conducted to the external environment in the form of smaller thermal resistance. Meanwhile, an air flow generating device may be disposed at the heat dissipation layer 91 close to the heat dissipation structure 100 to realize forced air convection, thereby further improving the heat dissipation efficiency of the heat dissipation structure 100.

The heat dissipation rib 911 thus arranged can also guide the hot air to be discharged from the side of the heat dissipation layer 91 more quickly on the basis of providing the air flow channel inclined in the vertical direction, and thus is also favorable for improving the heat dissipation efficiency of the whole heat dissipation layer 91.

In order to effectively identify the state of the heat dissipation structure 100, in one embodiment of the present disclosure, the heat dissipation structure 100 of the present disclosure may further include a position sensor (not shown) for detecting the relative position of the battery 300 and the first heat dissipation member 3 and/or the second heat dissipation member 4. In this way, the relative positions of the battery 300 and the first heat dissipation element 3 and/or the second heat dissipation element 4 can be identified by the position sensor, and whether the first heat dissipation element 3 and the second heat dissipation element 4 reach the clamping position or not is judged, so that whether the first heat dissipation element 3 and the second heat dissipation element 4 need to reach the refrigeration state or not is controlled, and energy conservation is facilitated.

Specifically, whether the first heat dissipation member 3 and the second heat dissipation member 4 reach the clamping position or not can be identified by the position sensor, and if the first heat dissipation member 3 and the second heat dissipation member 4 reach the clamping position, the refrigeration functions of the first heat dissipation member 3 and the second heat dissipation member 4 can be started to enable the first heat dissipation member and the second heat dissipation member to reach the refrigeration state, so that the battery 300 is cooled by heat dissipation. If the clamping position is released, the cooling functions of the first and second heat sinks 3 and 4 may be turned off, so that both the cooling functions are turned off to save energy.

It is understood that the position sensor of the present disclosure has various arrangement positions and arrangements, for example, in one embodiment of the present disclosure, the position sensor may be selected as two contact sensors and disposed at a side of the first and second heat dissipation members 3 and 4 contacting the battery 300, respectively, so that the position sensor may recognize whether the first and second heat dissipation members 3 and 4 reach or depart from the clamping position, thereby controlling the cooling function of the first and second heat dissipation members 3 and 4. In another embodiment, the position sensor may be provided as two proximity sensors respectively installed near the surfaces of the first and second heat dissipation members 3 and 4 contacting the battery 300 to recognize whether the first and second heat dissipation members 3 and 4 reach or depart from the clamping position, so that the cooling function of the first and second heat dissipation members 3 and 4 may be controlled.

In another embodiment of the present disclosure, the heat dissipation structure 100 of the present disclosure may further include a pressure sensor for measuring a pressure between the battery 300 and the first and/or second heat dissipation members 3 and 4 to identify whether the first and second heat dissipation members 3 and 4 reach or depart from the clamping position, thereby facilitating control of whether the first and second heat dissipation members 3 and 4 need to reach a cooling state, and facilitating energy conservation.

Specifically, whether the first heat dissipation member 3 and the second heat dissipation member 4 reach the clamping position or not can be judged by identifying the pressure value between the battery 300 and the first heat dissipation member 3 and the second heat dissipation member 4 through the pressure sensor, if the pressure value reaches the clamping position, the refrigeration functions of the first heat dissipation member 3 and the second heat dissipation member 4 can be started, so that the first heat dissipation member 3 and the second heat dissipation member 4 reach the refrigeration state, and the battery 300 is cooled by dissipating heat. If the clamping position is released, the cooling functions of the first and second heat sinks 3 and 4 may be turned off, so that both the cooling functions are turned off to save energy.

Wherein the pressure sensor of the present disclosure is also used for measuring the pressure of the elastic member 2. Like this, because when first radiating element 3 and second radiating element 4 are in the clamping state, the pressure of elastic component 2 is a certain numerical value, when first radiating element 3 and second radiating element 4 break away from the clamping state, the pressure of elastic component 2 is another numerical value, that is to say, can judge whether first radiating element 3 and second radiating element 4 are in the clamping state through measuring the pressure of elastic component 2 to be favorable to controlling whether first radiating element 3 and second radiating element 4 need reach the refrigeration state, be favorable to the energy saving.

In addition, the heat dissipation structure 100 of the present disclosure may further include a temperature sensor disposed on a side of the first or second heat dissipation member 3 or 4 contacting the battery 300, for detecting the temperature of the case of the battery 300 in real time, and when the temperature of the battery 300 decreases to a certain value, the heat dissipation (or cooling) power of the first and second heat dissipation members 3 and 4 may be adjusted to servo-control the temperature of the battery 300. For example, when the temperature of the battery 300 is lower than a certain value, the heat dissipation (or cooling) power of the first heat dissipation element 3 and the second heat dissipation element 4 may be reduced, so that the energy consumption can be reduced based on the heat dissipation; when the temperature of the battery 300 is higher than a certain value, the heat dissipation (or cooling) power of the first and second heat dissipation members 3 and 4 may be increased to improve the heat dissipation efficiency and ensure the heat dissipation effect.

According to another aspect of the present disclosure, as shown in fig. 11, there is also provided a battery charging cabinet 200 including at least one heat dissipation structure 100 according to any one of the above-mentioned embodiments. Therefore, the battery charging cabinet 200 of the present disclosure can cool down the casing of the battery 300 through the first heat dissipation member 3 and the second heat dissipation member 4, thereby achieving the effect of cooling down the electric core of the battery 300, and facilitating the battery charging cabinet 200 provided by the present disclosure to cool down the battery 300 quickly and safely. Meanwhile, the battery charging cabinet 200 of the present application has low requirements for the protection performance of the battery 300, and can be applied to most of the batteries 300; moreover, the volume, weight, manufacturing cost and maintenance cost of the related equipment of the whole heat dissipation structure 100 are low, and almost no working noise exists.
