Abstract
The utility model relates to a high temperature prevention power distribution cabinet, which comprises a cabinet body, a cooler, a fan and a plurality of heat collecting pipes, wherein the plurality of heat collecting pipes are adhered to the inner wall of the cabinet body and are provided with a plurality of air inlet holes; one end of the heat collecting pipe is connected with the air inlet port of the fan, the air outlet port of the fan is connected with the inlet of the cooler, and the outlet of the cooler is positioned in the internal space of the cabinet body and communicated with the internal space of the cabinet body. High-temperature air generated by each heat dissipation point in the cabinet body is collected to the cooler through the heat collection tubes and the fan, and is cooled by the cooler and then sent back to the cabinet body, air in the cabinet body is not exchanged with outside air, and outside dust and water vapor cannot be brought into the cabinet body when the temperature in the cabinet body is reduced.
Description
Technical Field
The utility model relates to a prevent high temperature switch board.
Background
When the temperature of a working environment is higher than 40, the working state of the electrical element is easy to be abnormal and the aging process of the electrical element can be accelerated; in the prior art, in order to reduce the temperature, the most common technology is to perform ventilation circulation heat dissipation on the inside of a cabinet body by using a fan, but the technology easily causes dust outside the cabinet body to be sucked into the inside of the cabinet body and attached to electrical elements, so that the electrical elements are abnormal in operation and heat dissipation.
Disclosure of Invention
The utility model aims to solve the above problem, provide a prevent high temperature power distribution cabinet, specifically realize by following technical scheme:
a high-temperature-resistant power distribution cabinet comprises a cabinet body, a cooler, a fan and a plurality of heat collecting pipes, wherein the heat collecting pipes are attached to the inner wall of the cabinet body and provided with a plurality of air inlet holes; one end of the heat collecting pipe is connected with the air inlet port of the fan, the air outlet port of the fan is connected with the inlet of the cooler, and the outlet of the cooler is positioned in the internal space of the cabinet body and communicated with the internal space of the cabinet body.
The high-temperature-resistant power distribution cabinet is further designed in that a first through hole and a second through hole are formed in the upper side wall of the cabinet body, the fan and the cooler are arranged on the outer side of the upper side wall, and an air inlet port of the fan is connected with the heat collecting pipe through the first through hole; an outlet of the cooler is butted against the second through hole.
The high-temperature-resistant power distribution cabinet is further designed in that the cooler comprises a shell and a finned tube longitudinally arranged on the inner wall of the shell, and two ports of the finned tube respectively form an inlet and an outlet of the cooler; the housing is also connected to a medium supply line and a medium return line which are connected to the cooling medium.
The high-temperature-resistant power distribution cabinet is further designed in that a plurality of flow blocking rings are arranged on the inner wall of the shell, and the flow blocking rings and fins of the finned tubes are arranged in a staggered mode.
The beneficial effects of the utility model reside in that:
high-temperature air generated by each heat dissipation point in the cabinet body is collected to the cooler through the heat collection tubes and the fan, and is cooled by the cooler and then sent back to the cabinet body, air in the cabinet body is not exchanged with outside air, and outside dust and water vapor cannot be brought into the cabinet body when the temperature in the cabinet body is reduced.

Fig. 2 is a schematic view of the internal structure of the cooler.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the high-temperature-resistant power distribution cabinet comprises a cabinet body 1, a cooler 2, a fan 3 and a plurality of heat collecting pipes 4, wherein the heat collecting pipes are attached to the inner wall of the cabinet body and provided with a plurality of air inlets; one end of the heat collecting pipe is connected with the air inlet port of the fan, the air outlet port of the fan is connected with the inlet of the cooler, and the outlet of the cooler is positioned in the internal space of the cabinet body and communicated with the internal space of the cabinet body.
High-temperature air generated by each heat dissipation point in the cabinet body is collected to the cooler through the heat collection tubes and the fan, and is cooled by the cooler and then sent back to the cabinet body, air in the cabinet body is not exchanged with outside air, and outside dust and water vapor cannot be brought into the cabinet body when the temperature in the cabinet body is reduced.
The upper side wall of the cabinet body is provided with a first through hole and a second through hole, the fan and the cooler are arranged on the outer side of the upper side wall, and an air inlet port of the fan is connected with the heat collecting pipe through the first through hole; an outlet of the cooler is butted against the second through hole.
The cooler 2 comprises a shell 21 and a finned tube 22 longitudinally arranged on the inner wall of the shell, wherein the two ports of the finned tube form an inlet and an outlet of the cooler respectively; a medium supply pipe 23 connected to the cooling medium and a medium return pipe 24 are also connected to the housing.
A cooling medium such as cold air or cold water is introduced into the casing through the medium supply tube, and the cooling medium is heat-exchanged with the finned tubes, so that the high-temperature air in the finned tubes is cooled.
The inner wall of the shell is provided with a plurality of flow blocking rings 25, and the flow blocking rings and the fins of the finned tubes are arranged in a staggered mode. The choking ring can enhance the heat exchange effect between the cooling medium and the finned tube.
