Description

Technical Field

[0001] The utility model relates to the technical field of the body of an electrical equipment box, and more specifically, to a heat dissipation structure of an electrical equipment box. Background Art

[0002] The body of an electrical equipment box, in a broad sense, can be regarded as a box structure for installing, protecting, and managing electrical equipment. Such equipment box bodies are widely used in multiple fields, including but not limited to power, construction, communication, industrial automation, etc. A distribution box is a small distribution device in a power supply system, which contains power switches and safety devices, and has a relatively simple structure. It is mostly used for terminal power distribution. It is the last-stage equipment of the power distribution system, far from the power supply center, and is a decentralized small-capacity power distribution device.

[0003] At present, when electrical equipment is working, it will generate a certain amount of heat. These heats accumulate inside the electrical equipment. If the inside of the electrical equipment cannot be dissipated in time and effectively, it will not only have a certain impact on the safe operation of the electrical components inside the electrical control box, but may also become an ignition source for fire and explosion accidents. Currently, existing electrical equipment is generally equipped with a fan for heat dissipation. However, due to the presence of different electrical equipment inside the box body, and the installation and distribution of the electrical equipment are usually irregular, when the fan drives the air flow to circulate inside the box body, it will be blocked by the electrical equipment, and then the air flow is not convenient to circulate smoothly, thereby affecting the heat dissipation effect of the heat dissipation inside the box body. In view of this, we propose a heat dissipation structure of an electrical equipment box. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a heat dissipation structure of an electrical equipment box to solve the technical problem that when the existing fan drives the air flow to circulate inside the box body, it will be blocked by the electrical equipment, and then the air flow is not convenient to circulate smoothly, thereby affecting the heat dissipation effect of the heat dissipation inside the box body.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A heat dissipation structure of an electrical equipment box, including a box body of the equipment box with a device compartment formed inside by opening.

[0006] Both sides of the inner wall of the device compartment inside the device box body are detachably provided with heat conduction components. The heat conduction components are symmetrically arranged, and the opposite ends of the heat conduction components are fixedly connected. An air duct for guiding the gas to flow is formed between the heat conduction components and the inner wall of the device box body.

[0007] The top of the device box body is detachably installed with a heat dissipation component for driving the gas to be discharged.

[0008] The heat conduction component includes a vertical heat conduction plate with a transverse heat conduction plate formed by bending towards one side at the top. The inner parts of the vertical heat conduction plate and the transverse heat conduction plate are respectively formed with a first convex part and a second convex part at equal intervals. The vertical heat conduction plate and the transverse heat conduction plate form a wavy structure through the first convex part and the second convex part.

[0009] In the utility model, by designing the heat conduction component, an air duct for guiding gas flow is formed between the heat conduction component and the inner wall of the equipment box body. When the electrical equipment in the equipment compartment generates high temperature during operation, the heat will be transferred to the vertical heat conduction plate and the transverse heat conduction plate through the heat absorption structure. Thus, when the heat dissipation component operates, external air enters the air duct and carries the heat inside the vertical heat conduction plate and the transverse heat conduction plate for discharge, thereby improving the heat dissipation effect of the electrical equipment in the equipment box body.

[0010] Preferably, a narrow channel for accelerating the gas is formed between the peak surface positions of the first convex part and the second convex part and the air duct. An endothermic structure is arranged on one side of the vertical heat conduction plate facing the inside of the equipment compartment.

[0011] Preferably, the endothermic structure includes a plurality of heat dissipation fins arranged in layers at equal intervals, and the heat dissipation fins are integrally connected to the vertical heat conduction plate.

[0012] Preferably, air inlet grooves communicating with the air duct are formed on both sides of the equipment box body. Waterproof covers are formed outside the air inlet grooves on both sides of the equipment box body. A box door is movably hinged to one side of the equipment box body through a hinge.

[0013] Preferably, the heat dissipation component includes a mounting frame detachably installed at the top of the heat dissipation component. A bearing plate is detachably installed inside the mounting frame, and a box cover is detachably installed at the top of the mounting frame. An exhaust groove is formed in the middle at the bottom of one side of the box cover.

[0014] Preferably, heat dissipation fans are detachably distributed in a rectangular array at the top of the bearing plate, and dust-proof nets are detachably installed at the positions of the heat dissipation fans at the bottom of the bearing plate. A rectangular exhaust groove is formed inside the bearing plate at the positions of the heat dissipation fans and the bearing plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model designs a heat conduction component, and forms an air duct for guiding gas flow between the heat conduction component and the inner wall of the equipment box body. When the electrical equipment in the equipment compartment generates high temperature during operation, the heat will be transferred to the vertical heat conduction plate and the horizontal heat conduction plate through the heat absorption structure. Thus, when the heat dissipation component operates, external air enters the air duct, and carries the heat inside the vertical heat conduction plate and the horizontal heat conduction plate for discharge, thereby improving the heat dissipation effect of the electrical equipment in the equipment box body, and solving the problem that when the existing fan drives the air flow to circulate inside the box body, it will be blocked by the electrical equipment, which further causes the air flow to be inconvenient to circulate smoothly, thus affecting the heat dissipation effect of the heat dissipation inside the box body.

[0017] 2. The utility model also designs the vertical heat conduction plate and the horizontal heat conduction plate into a wavy structure through the first convex part and the second convex part, and a narrow channel is formed between the peak surfaces of the first convex part and the second convex part and the air duct. When driving the external gas to pass through the narrow channel during the operation of the heat dissipation component, since the area of the narrow channel is smaller than that of other areas, the gas will accelerate when passing through this area. The wavy structure of the vertical heat conduction plate and the horizontal heat conduction plate is conducive to realizing the multi-stage acceleration of the gas, and improving the heat dissipation effect of the electrical equipment inside the equipment box body by increasing the gas flow rate.
