Description

Technical Field

[0001] This utility model relates to the field of cabinet heat dissipation technology, and in particular to a heat dissipation device for a control cabinet. Background Technology

[0002] In application number CN214204563U, it is proposed that the heat generated by the electrical appliances inside the existing control cabinet during use can only be diffused outward through the heat dissipation window, which has a poor diffusion effect. When the heat accumulated on the surface of the electrical appliances inside the control cabinet is difficult to dissipate, it will cause the electrical appliances to overheat and be damaged. The application document achieves active heat dissipation through heat conduction plate, heat dissipation fins and liquid inlet pipe. However, during the active cooling process, hot air will be discharged into the cabinet, and it is difficult for the cabinet to cool down in a short time. Utility Model Content

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0004] To address the aforementioned problems, this utility model provides the following technical solution: A heat dissipation device for a control cabinet includes a heat dissipation structure and a fan structure. The fan structure is disposed at one end of the heat dissipation structure, and one end of the heat dissipation structure is disposed on the cabinet body, with the heat dissipation cavity of the heat dissipation structure connected to the outside of the cabinet. An exhaust pipe connected to the top of the heat dissipation structure is also connected to the outside of the cabinet.

[0005] Preferably, the heat dissipation structure is located inside the cabinet cavity of the cabinet.

[0006] Preferably, the top of the heat dissipation structure is provided with a groove, and the back of the heat dissipation structure is provided with heat dissipation fins.

[0007] Preferably, the heat dissipation structure has a flow guide shell at the bottom, and the heat dissipation fins are located in the heat dissipation cavity formed by the flow guide shell and the heat dissipation structure.

[0008] Preferably, the fan structure includes a housing, a partition, a cooling fan, and a mesh, with the housing disposed at one end of the cooling structure.

[0009] Preferably, the outer casing has several partitions, with cooling fans between adjacent partitions, and a mesh is provided on the outer casing.

[0010] The beneficial effects of this utility model are: by placing the electrical appliances inside the cabinet on top of the heat dissipation structure, the heat dissipation structure can be fully conducted and the heat conduction can be optimized. Heat dissipation fins can be set in the heat dissipation cavity. The fan structure actively draws air from outside the cabinet, passes through the heat dissipation cavity, and then discharges it through the exhaust pipe. The heat generated by the electrical appliances does not pass through the cabinet cavity of the cabinet body throughout the process, which achieves a better heat dissipation effect for the electrical appliances inside the cabinet.

Detailed Implementation

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example

[0021] Reference Figures 1 to 6 This embodiment of the present invention provides a heat dissipation device for a control cabinet, including a heat dissipation structure 200 and a fan structure 300. The fan structure 300 is disposed at one end of the heat dissipation structure 200. One end of the heat dissipation structure 200 is disposed on the cabinet body 100, and the heat dissipation cavity 200a of the heat dissipation structure 200 is connected to the outside of the cabinet. The heat dissipation structure 200 is disposed inside the cabinet cavity 101 of the cabinet body 100, and the exhaust pipe 202 connected to the top of the heat dissipation structure 200 is connected to the outside of the cabinet.

[0022] Specifically, the electrical appliances inside the cabinet 100 are installed on top of the heat dissipation structure 200 so that they are in contact with each other. The heat dissipation structure plays a role in heat conduction. By activating the fan structure 300, the heat absorbed by the heat dissipation structure 200 is discharged to the outside of the cabinet 100 through the exhaust pipe 202 connected to the top, so that the temperature of the cabinet cavity 101 of the cabinet 100 rises slowly (a double-layer structure can be used or an exhaust pipe 202 made of a material with poor heat insulation can be used), thereby better and more accurately and actively dissipating heat from the electrical appliances in the cabinet 100 without affecting the overheating of other electrical appliances inside the cabinet 100.

[0023] For example, the top of the heat dissipation structure 200 is provided with a groove 200b, and the back of the heat dissipation structure 200 is provided with heat dissipation fins 203. By providing a groove 200b on the top of the heat dissipation structure 200, thermal conductive paste (silicone, etc.) can be provided in the groove 200b so that the heat dissipation structure 200 can make full contact with the surface of the electrical appliance. By increasing the heat dissipation fins 203, the thermal conductivity of the heat dissipation structure 200 can be improved.

[0024] For example, the heat dissipation structure 200 has a flow guide shell 201 at the bottom, and the heat dissipation fins 203 are located in the heat dissipation cavity 200a formed by the flow guide shell 201 and the heat dissipation structure 200. The flow guide shell 201 is V-shaped, and fan structures 300 are symmetrically arranged thereon. The exhaust pipe 202 is located at the top of the V-shape. When the two symmetrical fan structures 300 work at the same time, the two airflows blow towards the V-shaped flow guide shell 201 at the same time. As the space of the V-shaped flow guide shell 201 gradually shrinks, according to Bernoulli's principle, the airflow speed increases and the temperature decreases. This is conducive to the rapid cooling of the heat dissipation structure 200 and the heat dissipation fins 203 and the rapid exhaust of hot air, maintaining the temperature of the cabinet cavity 101 of the cabinet 100, and further optimizing the problem of overheating of other electrical appliances in the cabinet 100.

[0025] For example, the fan structure 300 includes a housing 301, partitions 301a, cooling fans 302, and a mesh 303. The housing 301 is located at one end of the heat dissipation structure 200. The housing 301 has several partitions 301a, here two partitions 301a are provided. Cooling fans 302 are provided between adjacent partitions 301a. There are three cooling fans 302, depending on the size of the heat dissipation structure 200 and the airflow guide shell 201, as well as the size of the cooling fans 302. The housing 301 is provided with a mesh 303 for protection.
