Embodiment 1

[0029] Figure 1-5 Shown is an electric control cabinet that maintains a constant temperature, including a cabinet body 1 and a cabinet door 101 for covering the cabinet body 1, the top plate of the cabinet body 11 is equipped with a semiconductor refrigeration device 2, and the semiconductor refrigeration device 2 It includes an installation box body 201, a semiconductor cooling chip 202 installed in the installation box body 201, a first heat sink 203 connected to the cold end of the semiconductor cooling chip 202, and a first heat sink 203 connected to the hot end of the semiconductor cooling chip 202. The second heat sink; the first heat sink 203 is located in the cabinet 1, the second heat sink 204 is located outside the cabinet 1; the installation box 201 is located in the cabinet 1 Part is a cold chamber, and the part located outside the cabinet 1 is a hot chamber, the bottom of the cold chamber and the top of the hot chamber are both openings, and an exhaust fan 205 is...

Embodiment 2

[0041] like Image 6 Shown is an electric control cabinet that maintains a constant temperature. The difference from Embodiment 1 is that the thermal cavity includes a heat insulating part 208 and a heat dissipation part 209, and the heat insulating part 208 covers the second heat sink 204. Close to the half part of the cabinet body 1, the heat dissipation part 209 covers the other half of the second cooling fin 204 away from the cabinet body 1; the inner wall of the heat insulation part 208 is provided with a thermal insulation layer (not shown in the figure) Out), the side wall of the heat dissipation part 209 is provided with a number of mesh holes 201. The heat insulation part can prevent the heat of the second heat sink 204 from flowing back to the top plate of the cabinet 1 , and exchange heat with the inside of the cabinet 1 , affecting the cooling rate of the cabinet 1 . The mesh holes of the heat dissipation part can speed up the heat dissipation efficiency of the se...

Abstract

The invention provides an electric control cabinet capable of keeping a constant temperature. The cabinet comprises a cabinet body and a cabinet door used for covering the cabinet body, a semiconductor refrigeration device is installed on a top plate of the cabinet body, and the semiconductor refrigeration device comprises an installation box body, a semiconductor refrigeration sheet installed inthe installation box body, a first cooling fin connected with the cold end of the semiconductor refrigeration sheet and a second cooling fin connected with the hot end of the semiconductor refrigeration sheet; the first cooling fin is located in the cabinet body, and the second cooling fin is located outside the cabinet body. The upper and lower ends of the mounting box body are open and are provided with exhaust fans; a controller and a temperature sensor are arranged in the cabinet body, the temperature sensor is installed at the bottom of the cabinet body, and the temperature sensor and thesemiconductor chilling plate are both connected with the controller. The temperature in the cabinet body is preset through the temperature sensor, and the semiconductor chilling plate is started or stopped according to the temperature, so that the interior of the cabinet body is kept in a constant temperature state, electrical components are prevented from breaking down due to over-high working environment temperature, the fault rate is reduced, and the safety is improved.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to an electric control cabinet for maintaining a constant temperature. Background technique [0002] In the existing electrical control cabinet, a large amount of heat is generated during the use of the electrical components in the cabinet. If the working environment temperature of electrical components is too high, it will cause failure or even fire accidents, seriously affecting production safety. [0003] At present, the common heat dissipation method of the electric control cabinet is to install cooling fans on one or both sides of the upper part of the electric control cabinet, but the heat dissipation efficiency of the cooling fan is slow, and the sealing of the electric control cabinet cannot be realized, and dust is easy to enter the cabinet. Contents of the invention [0004] Therefore, the purpose of the present invention is to provide an electric control c...
