Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to an electrical cabinet with a heat dissipation structure. Background Technology

[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. The materials used in electrical cabinet manufacturing are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for electrical cabinet manufacturing. Electrical cabinets have a wide range of applications, mainly in the chemical industry, environmental protection industry, power systems, metallurgical systems, industrial sectors, nuclear power industry, fire safety monitoring, transportation industry, etc. All electrical cabinets require a heat dissipation structure to ensure the proper functioning of the internal components.

[0003] Chinese patent CN209029699U discloses an electrical cabinet with a heat dissipation structure. The cabinet includes a cabinet body, a door pivotally mounted on the front of the cabinet body, a mounting bracket pivotally mounted inside the cabinet body via a longitudinal pivot, a guide rail positioned on the front of the mounting bracket, and a heat dissipation structure mounted on the cabinet body. The heat dissipation structure includes a first fan located at the top of the cabinet body and a first enclosure panel mounted on the door. The mounting bracket, door, and first enclosure panel together form a first heat dissipation channel. The guide rail is located within the first heat dissipation channel, and the air outlet of the first heat dissipation channel is aligned with the first fan. When electrical control components are mounted on the guide rail, they are also located within the first heat dissipation channel. The airflow generated when the first fan operates is concentrated, effectively removing the heat generated by the electrical control components during operation, thus optimizing the heat dissipation effect of the electrical cabinet and effectively delaying the thermal aging of the electrical control components.

[0004] Although the device is equipped with a fan to dissipate heat from the electrical cabinet, the maintenance of the heat dissipation components is quite cumbersome after prolonged use, and the air duct coverage in the aforementioned comparative document is small, resulting in an unsatisfactory heat dissipation effect.

[0005] Therefore, an electrical cabinet with a heat dissipation structure is needed. Utility Model Content

[0006] The purpose of this utility model is to provide an electrical cabinet with a heat dissipation structure to solve the problems mentioned in the background art, such as the cumbersome maintenance of heat dissipation components after long-term use, and the small air duct coverage and unsatisfactory heat dissipation effect in the aforementioned comparative documents.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electrical cabinet with a heat dissipation structure, comprising a mounting plate and a base plate, a cabinet body fixedly mounted on the top surface of the mounting plate, an installation mechanism fixedly mounted on the inner wall of the cabinet body, and a heat dissipation mechanism provided on the side of the installation mechanism; the installation mechanism includes a guide rail, a through hole fixedly opened on the side of the cabinet body, a guide rail fixedly mounted on the inner wall of the through hole, an installation frame slidably mounted on the side of the guide rail, a connecting block fixedly mounted on the side of the installation frame, a locking block fixedly mounted on the side of the connecting block, an installation block fixedly mounted on the inner wall of a groove opened in the cabinet body, a spring fixedly mounted on the side of the installation block, the side of the spring being engaged with the side of the locking block, and a sliding groove fixedly opened on the side of the installation frame, the inner wall of the sliding groove being slidably connected to the side of the guide rail.

[0008] Preferably, the heat dissipation mechanism includes a mounting bracket, a heat dissipation component is fixedly mounted on the inner wall of the mounting bracket, and a fan assembly is fixedly disposed inside the heat dissipation component.

[0009] Preferably, a handle is fixedly installed on the side of the mounting frame, an inner dustproof grille is snapped into the inner wall of the groove opened on the side of the cabinet, and an outer dustproof grille is snapped into the inner wall of the groove opened on the side of the cabinet.

[0010] Preferably, a rain shield is fixedly installed on the side of the cabinet.

[0011] Preferably, a support rod is fixedly installed on the top surface of the base plate, and threaded holes are opened through the top and bottom of the base plate, with fixing bolts threaded into the inner wall of the threaded holes.

[0012] Preferably, a hinge is fixedly installed on the side of the cabinet, a door is fixedly installed on the side of the hinge, a through groove is fixedly opened on the side of the door, a glass observation window is fixedly installed on the inner wall of the through groove, a handle is fixedly installed on the top surface of the door, and a rubber ring is fixedly installed on the side of the door.

[0013] Preferably, a partition is fixedly installed inside the cabinet, a top plate is fixedly installed on the top surface of the cabinet, and a buffer pad is fixedly installed on the side of the cabinet, with the side of the buffer pad corresponding to the side of the rubber ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) When the heat dissipation mechanism of this electrical cabinet needs to be inspected, maintained, or cleaned after a long period of use, the handle is gripped and pulled to move the mounting frame on the side of the guide rail. The connecting block is then pulled to move, causing the locking block to disengage from the spring, thus detaching the mounting frame from the cabinet. This allows for the inspection and maintenance of the heat dissipation mechanism. After inspection and maintenance, the slide is aligned with the guide rail and pushed inward to engage the locking block with the spring, completing the installation. This solves the problem of cumbersome inspection and maintenance of heat dissipation components after long-term use, improving the efficiency and practicality of the device.

[0016] 2) When inspecting the interior of the electrical cabinet, simply grasp the handle and pull to open the door for maintenance. When dissipating heat from the inside of the cabinet, the heat dissipation components are activated. Multiple sets of heat dissipation components on the side of the cabinet form multiple air ducts. The air ducts draw in cool air from the outside into the cabinet and exhaust it through the heat dissipation components on the other side. During this process, the heat inside the cabinet is dissipated, thus completing the heat dissipation operation. This solves the problem of small air duct coverage and insufficient heat dissipation effect, and improves the heat dissipation quality of the device. Attached Figure Description

[0026] Specifically, when the heat dissipation mechanism 4 needs to be inspected, maintained, or cleaned after long-term use, grip the handle 403 and pull it. This will further cause the mounting frame 304 to slide on the side of the guide rail 301, and further pull the connecting block 306 to move. This will cause the locking block 307 to disengage from the spring 303, completing the removal of the mounting frame 304 from the cabinet 2. Then, the heat dissipation mechanism 4 can be inspected and maintained. After inspection and maintenance, align the slide groove 305 with the guide rail 301 and push it inward so that the locking block 307 engages with the spring 303, completing the installation.

[0029] Specifically, when inspecting the inside of cabinet 2, grip handle 12 and pull it to open door 10 to perform maintenance work; when dissipating heat inside cabinet 2, open heat dissipation component 402 to dissipate heat, and form multiple air ducts through multiple heat dissipation components 402 set on the side of cabinet 2. The air ducts draw in cold air from the outside into cabinet 2 and exhaust it through the heat dissipation component 402 on the other side. During this process, the heat inside cabinet 2 will be dissipated, completing the heat dissipation work.
