[0001] The utility model relates to the technical field of electrical cabinet dehumidification, in particular to a heat conduction structure and a dehumidification device with the same. Background Art

[0002] An electrical cabinet is a cabinet made of steel materials to protect components to work properly, which is widely used in industries such as chemical industry, environmental protection, power system, metallurgy, etc. A dehumidification device is usually arranged on the electrical cabinet to remove water vapor in the air inside the cabinet, keep the inside of the cabinet dry, and prevent short circuits of the internal circuits of the cabinet. However, there are still some drawbacks in the existing dehumidification devices, such as:

[0003] 1. The heat conduction effect of the heat conduction structure is not good, which affects the condensation dehumidification effect of the refrigeration sheet. Therefore, if the existing dehumidification device wants to obtain a better dehumidification effect, it is necessary to increase the power of the refrigeration sheet and at the same time increase the volume of the dehumidification device.

[0004] 2. Most of the existing dehumidification devices are fixedly installed in the electrical cabinet, occupying the space of the electrical cabinet. Content of the Utility Model

[0005] To achieve the above object, the utility model provides a heat conduction structure, which includes a first heat conduction plate, a refrigeration sheet and a second heat conduction plate. The refrigeration sheet has a hot surface and a cold surface. The hot surface is attached to the front of the first heat conduction plate. A plurality of first hot end heat conduction sheets are arranged on the back of the first heat conduction plate. The second heat conduction plate is attached to the cold surface. A plurality of cold end heat conduction sheets are arranged on the second heat conduction plate. A water receiving tank is arranged below the cold end heat conduction sheets.

[0006] In some possible embodiments, the surface of the first hot end heat conduction sheet / the cold end heat conduction sheet is in a tooth-shaped or corrugated or square wave-shaped with uneven ups and downs.

[0007] In some possible embodiments, a plurality of second hot end heat conduction sheets are arranged on the front of the first heat conduction plate, and the second hot end heat conduction sheets are respectively arranged on the left and right sides of the refrigeration sheet.

[0008] In some possible embodiments, a sealing baffle is arranged at the upper end of the refrigeration sheet. The cold end heat conduction sheets and the second hot end heat conduction sheets are both arranged vertically. The air flow flows through the cold end heat conduction sheets from top to bottom and flows out from bottom to top between two adjacent second hot end heat conduction sheets.

[0009] In some possible embodiments, an installation frame is further included. The installation frame is fixed to the first heat conduction plate and forms an installation groove on the first heat conduction plate. The refrigeration sheet is attached to the installation groove. The second heat conduction plate is fixedly connected to the installation frame and attached to the cold surface.

[0010] In some possible embodiments, the lower end of the cold-end heat conducting sheet extends obliquely downward from the cold surface and forms a tip water collecting part.

[0011] In some possible embodiments, the first hot-end heat conducting sheet and the first heat conducting plate are integrally formed, and the cold-end heat conducting sheet and the second heat conducting plate are integrally formed.

[0012] The present utility model further provides a dehumidifying device, which includes a housing and a heat conducting structure as described in the above embodiments. The housing is fixedly installed on the cabinet door. The heat conducting structure is arranged inside the housing. An air inlet and an air outlet are formed on the housing. The air inlet is formed on the end face of the housing away from the cabinet door and is aligned with the upper part of the cold-end heat conducting sheet. The air outlets are arranged on the left and right sides of the housing, and a fan is arranged at the air outlets.

[0013] In some possible embodiments, a circuit board is further arranged inside the housing, and an inwardly concave interface groove is formed on the side surface of the housing. The connector of the circuit board is arranged in the interface groove.

The cold surface of the refrigerating sheet is attached to the first heat conducting plate, and a plurality of cold-end heat conducting sheets are further arranged on the first heat conducting plate. The first heat conducting plate quickly conducts the heat of the refrigerating sheet, and the second heat conducting plate can quickly cool down to improve the condensation dehumidification effect. A water receiving groove is arranged below the cold-end heat conducting sheet to receive the condensed water droplets. It can be seen that the heat conducting structure of the present utility model has a good heat conducting effect and can be made smaller on the premise of meeting the heat conducting effect, thereby reducing the occupied area of the dehumidifying device in the cabinet.

[0015] The dehumidifying device of the present utility model is installed on the cabinet door.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figures 1 to 3 A heat conduction structure shown, which includes a first heat conduction plate 10, a second heat conduction plate 20, and a refrigeration chip 30. The refrigeration chip 30 has a hot surface and a cold surface. A plurality of first hot end heat conduction fins 101 are arranged on the back surface of the first heat conduction plate 10, and a plurality of cold end heat conduction fins 201 are arranged on the second heat conduction plate 20. Among them, the hot surface is attached to the front surface of the first heat conduction plate 10, so that the first hot end heat conduction fins 101 on the first heat conduction plate 10 can quickly conduct and dissipate the heat of the refrigeration chip 30. The second heat conduction plate 20 is attached to the cold surface, so that the cold end heat conduction fins 201 can quickly cool and condense the water vapor in the air thereon, achieving the effect of rapid condensation and dehumidification. A water receiving tank 40 is further arranged below the cold end heat conduction fins 201, and a drain port 41 is arranged at the lower end of the water receiving tank 40. The water droplets condensed on the cold end heat conduction fins 201 can drip into the water receiving tank 40 and be discharged through the drain port 41.

[0024] In some possible embodiments, referring to Figure 1 And Figure 2As shown, the surfaces of the first hot-end heat conducting fin 101 / cold-end heat conducting fin 201 are in a serrated, corrugated or square-wave shape with undulations. The purpose is that when the air flow passes through the first hot-end heat conducting fin 101 / cold-end heat conducting fin 201, it can contact the surface of the first hot-end heat conducting fin 101 / cold-end heat conducting fin 201 as much as possible, so that the air flow contacting the surface of the first hot-end heat conducting fin 101 can take away more heat, that is, the heat dissipation effect of the first hot-end heat conducting fin 101 is better; and the air flow contacting the surface of the cold-end heat conducting fin 201 can be cooled to condense water droplets on the cold-end heat conducting fin 201, that is, the condensation effect on the cold-end heat conducting fin 201 is better. Or on the premise that the condensation effect of the cold-end heat conducting fin 201 meets the requirements, the area or length of the cold-end heat conducting fin 201 can be designed smaller. Therefore, such a design can also reduce the volume of the heat conducting structure.

[0025] In some possible embodiments, referring to Figure 1 With Figure 2 As shown, a plurality of second hot-end heat conducting fins 102 are arranged on the front surface of the first heat conducting plate 10. The second hot-end heat conducting fins 102 are respectively arranged on the left and right sides of the refrigerating sheet 30. Such a design can make the condensed air flow act on the second hot-end heat conducting fins 102, so as to achieve the effect of cooling the first heat conducting plate 10; furthermore, a sealing baffle 50 is arranged at the upper end of the refrigerating sheet 30. The cold-end heat conducting fin 201 and the second hot-end heat conducting fin 102 are both arranged vertically. The air flow can be blown into the upper end of the cold-end heat conducting fin 201, flow downward between two adjacent cold-end heat conducting fins 201, and then flow upward between two adjacent second hot-end heat conducting fins 102. That is, the water vapor in the air flow containing water vapor condenses on the surface of the cold-end heat conducting fin 201 after being cooled by the cold-end heat conducting fin 201 and drips from the lower end of the cold-end heat conducting fin 201 into the water receiving tank 40. At this time, the air flow without water vapor has a lower temperature. This air flow flows upward through the second hot-end heat conducting fin 102, and can cool and dissipate heat from the second hot-end heat conducting fin 102 / the first heat conducting plate 10, so as to improve the heat dissipation effect of the first heat conducting plate 10 / the hot surface; and the air flow flowing downward through the cold-end heat conducting fin 201 can blow the water droplets from the lower end of the cold-end heat conducting fin 201 into the water receiving tank 40, avoiding excessive water droplets accumulating at the lower end of the cold-end heat conducting fin 201, which may cause the air flow to take away water vapor from the water droplets again and reduce the condensation and dehumidification effect.

[0026] In some possible embodiments, referring to Figure 2As shown, the heat conduction structure further includes a mounting frame 60. The mounting frame 60 can be fixedly connected to the front surface of the first heat conduction plate 10 by bolts, and a mounting groove for accommodating the refrigerating sheet 30 is formed on the front surface of the first heat conduction plate 10. The second heat conduction plate 20 can also be fixedly connected to the mounting frame 60 by bolts, that is, the refrigerating sheet 30 is arranged between the first heat conduction plate 10 and the second heat conduction plate 20. The mounting frame 60 can not only restrict the degrees of freedom of the refrigerating sheet 30 in the horizontal and vertical directions, but also the thickness of the mounting frame 60 can prevent the first heat conduction plate 10 and the second heat conduction plate 20 from clamping and damaging the refrigerating sheet 30.

[0027] In some possible embodiments, referring to Figure 2 and Figure 5 As shown, the lower end of the cold-end heat conduction sheet 201 extends obliquely downward from the cold surface and forms a tip water collection part 202. The tip water collection part 202 is far from the cold surface and the second heat conduction plate 20. The purpose is to prevent the water droplets condensed on the tip water collection part 202 from spreading along the surface of the cold-end heat conduction sheet 201 and then seeping in from the connection between the refrigerating sheet 30 or the water receiving tank 40 and the first heat conduction plate 10, thus causing the risk of leakage or even damage to the refrigerating sheet 30.

[0028] In some possible embodiments, the first hot-end heat conduction sheet 101 and the first heat conduction plate 10 are integrally formed, and the cold-end heat conduction sheet 201 and the second heat conduction plate 20 are integrally formed.

[0029] The present utility model further provides a dehumidifying device. Referring to Figure 4 and Figure 5 As shown, the dehumidifying device can be fixedly installed on the cabinet door and can be moved with the cabinet door to be removed from the cabinet body. It includes a housing 70 and a heat conduction structure as described in the above embodiments. The heat conduction structure is fixedly installed in the housing 70. A circuit board 74 and a fan 73 are also arranged in the housing 70. An air inlet 71 and an air outlet 72 are formed on the housing 70. The air inlet 71 is arranged on the end face of the housing 70 far from the cabinet door and is located in the upper part of the cold-end heat conduction sheet 201. The air flow blown in from the air inlet 71 can be conveyed downward from the upper end of the cold-end heat conduction sheet 201. At this time, the air flow is cooled by the cold-end heat conduction sheet 201, so that the water vapor in the air flow condenses on the cold-end heat conduction sheet 201. The air flow continues to blow downward and can also blow the condensed water droplets into the water receiving tank 40. After the air flow blows out from the lower end of the cold-end heat conduction sheet 201, it then flows upward from the lower end of the second hot-end heat conduction sheet 102, so as to cool and dissipate heat from the second hot-end heat conduction sheet 102 / the first heat conduction plate 10. Finally, the air flow blows out from the air outlet 72 to achieve the effect of dehumidification; the air outlet 72 is arranged on the left and right sides of the housing 70, and the fan 73 is installed in the air outlet 72. Such a design can avoid the problem that raindrops enter the interior of the dehumidifying device from the air outlet 72 when the dehumidifying device is opened with the cabinet door during rain.

[0030] In some possible embodiments, with reference to Figure 4 As shown, a concave interface groove 75 is formed on the side surface of the housing 70, and the connector 76 on the circuit board 74 is arranged in the interface groove 75. Such a design can avoid the problem that the connector 76 is damaged due to water ingress when the dehumidifying device is opened with the cabinet door during rain.

Any changes or substitutions within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
