Problems solved by technology

[0004] However, the applicant found that the above-mentioned existing high-voltage switch cabinets with regular heat dissipation generally have relatively weak internal heat dissipation methods, and adopt a cabinet structure without active cooling, resulting in passive cooling of the internal structure, making it difficult to quickly take out the internal heat, resulting in Accumulation, and the heat generated by electrical components is the main cause of this situation, while conventional cabinets lack heat conduction and heat dissipation structures that directly cooperate with electrical components, making it difficult to volatilize heat

Embodiment 1

[0030] see Figure 1-6 , this embodiment discloses a high-voltage switch cabinet with timed heat dissipation, including a cabinet shell 1 and an installation door 2 at one end of the cabinet shell 1, the other end of the cabinet shell 1 is installed with a rear cover 3, and the cabinet shell 1 An electrical cabinet mounting frame 4 is installed inside the electrical cabinet, an electrical installation base 8 is installed on the inner side of the electrical cabinet installation frame 4, a diversion base 23 is installed on the inner side of the electrical installation base 8, and a heat conduction base 22 is installed at one end of the diversion base 23. The upper end of the flow base 23 is provided with a liquid inlet slot 25, the lower end of the diversion base 23 is provided with a liquid outlet slot 26, and the outer side of the flow base 23 is provided with a liquid inlet port 27 at one end of the liquid inlet slot 25 to guide the flow of water. The outer side of the base 2...

Embodiment 2

[0034] This embodiment is an improvement made on the basis of the high-voltage switch cabinet with timed heat dissipation in the embodiment. For details, please refer to Figure 1-6 One side of the guide base 23 is provided with a curved guide pipe 24 , and both ends of the curved guide pipe 24 are connected with the liquid inlet groove 25 .

[0035] Therefore, there is a cooling cavity between the guide base 23 and the heat conduction base 22 , so that the cooling liquid flows faster when it flows between the guide base 23 and the heat conduction base 22 , so that the cooling liquid is in contact with the inner wall of the heat conduction base 22 . If the time is too short, it is difficult to conduct more heat;

[0036] Through the curved structure of the curved guide tube 24, the cooling liquid can extend its flow area when passing through, and at the same time, the heat conduction efficiency between the cooling liquid and the inner wall of the guide base 23 will not be weak...

Embodiment 3

[0038] This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-6 , the inner wall of the heat-conducting base 22 is provided with a curved guide pipe 24 , and the curved guide pipe 24 is used to be installed inside the curved guide pipe 24 .

[0039] Through the function of the curved guide tube 24, the heat conduction area of ​​the heat conduction base 22 is increased, and more heat can be transferred. At the same time, the curved guide tube 24 is arranged along the trajectory of the curved guide tube 24 and placed in the curved guide tube. 24, so that when the cooling liquid flows inside the curved guide tube 24, the bonding area with the heat conduction base 22 is greatly increased. After the heat conduction area is increased, the heat transfer effect of the cooling liquid is greatly increased. .

Abstract

The invention relates to the technical field of electrical cabinets, and discloses a timed heat dissipation high-voltage switch cabinet, which comprises a cabinet body shell and a mounting door body at one end of the cabinet body shell, a rear cover plate is mounted at the other end of the cabinet body shell, and an electrical cabinet mounting frame is mounted in the cabinet body shell. An electric appliance installation base is installed on the inner side of the electric appliance cabinet installation frame, a flow guide base is installed on the inner side of the electric appliance installation base, a heat conduction base is installed at one end of the flow guide base, a liquid inlet hole groove is formed in the upper end of the flow guide base, and a liquid outlet hole groove is formed in the lower end of the flow guide base. A liquid inlet port located at one end of the liquid inlet hole groove is formed in the outer side of the flow guide base. According to the invention, under the action of additionally arranging the wind shield and the flow guide plate, when gas is located in the air guide pipeline and under the condition that the flow speed is not changed, the flow area is narrowed, and the flow speed of the gas in the air guide pipeline is increased, so that the traction effect of the gas is improved, and the traction function of the gas in the cabinet body shell is completed.

Description

technical field [0001] The invention relates to the technical field of electrical cabinets, in particular to a high-voltage switch cabinet for timing heat dissipation. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of the components. The electrical cabinets are generally made of hot-rolled steel and cold-rolled steel. Cold-rolled steel sheets are softer than hot-rolled steel sheets, and are more suitable for the production of electrical cabinets. Electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] Chinese invention patent CN201810268039 discloses an electrical cabinet with timing heat dissipation function. It includes a casing, a fan mounting seat is installed at the bottom end of the casing, and the vertical center line of the fan m...
