Problems solved by technology

The heat dissipated by the electric cabinet with this structure is partly absorbed by the backboard of the electric cabinet and radiated from the side of the backboard inside the cabinet to the inside of the electric cabinet again, which reduces the heat dissipation effect of the entire electric cabinet

Embodiment 1

[0022] The heat dissipation method of the circulating electric cabinet adopts a plurality of heat pipes 1 to connect with the circulating electric cabinet 2, wherein: the evaporating section 3 of the heat pipe 1 extends into the inner circulation chamber 6 of the electric cabinet equipped with heat dissipation components 5 and is connected with the heat dissipation elements. The device 5 is connected, the condensation section 4 of the heat pipe 1 is located outside the inner circulation cavity 6 of the electric cabinet, the evaporation section 3 of the heat pipe 1 collects the heat generated by the work of the heat dissipation component 5, and transfers the collected heat to the circuit located in the electric cabinet. The condensation section 4 outside the circulation cavity 6 in the cabinet 2 dissipates heat to the atmospheric environment outside the circulation cabinet body 2 through the condensation section 4 of the heat pipe 1 . In this embodiment, a through hole is opened...

Embodiment 2

[0026] This embodiment is a further improvement on the basis of embodiment 1. Compared with embodiment 1, in this embodiment, the condensation section 4 of the heat pipe 1 passes through the inner circulation cavity 6 and has a through hole and is located in the electric cabinet. In the outer circulation chamber 9 of the electric cabinet, a heat dissipation terminal piece 10 is arranged in the outer circulation chamber 9 of the electric cabinet, and the condensation section 4 of the heat pipe 1 is fixedly connected with the heat dissipation terminal piece 10 . Wherein: the heat dissipation terminal piece 10 includes a plurality of fins 11 arranged in parallel, on the fins 11, there are turned holes 12 matching the size of the condensation section of the heat pipe 1 (that is, there are through holes on the fins 11, and there are through holes in the through holes. One end of the hole is provided with a flange), and the condensation section 4 of the heat pipe 1 passes through the...

Embodiment 3

[0030]This embodiment is a further improvement on the basis of Embodiment 2. Compared with Embodiment 2, the heat dissipation terminal piece 10 in this embodiment adopts an integrated radiator, and the condensation section 4 of the heat pipe 1 is connected to the integrated radiator. , the specific connection method is to open a mounting hole (not shown in the figure) on the integrated radiator, extend the condensation section 4 of the heat pipe 1 into the installation hole and fix the condensation section 4 of the heat pipe 1 (such as welding, sticking connected, etc.) on the integral heatsink. The rest of the structure of this embodiment is the same as that of Embodiment 2, and will not be repeated in this embodiment.

Abstract

The invention discloses a heat radiation method for a circulation electrical cabinet. More than one heat pipe (1) are connected with the circulation electrical cabinet (2), an evaporation section (3) of the heat pipe (1) extends into an inner circulation chamber (6) of an electric cabinet in which a heat radiation component (5) is mounted, and is connected with the heat radiation component (5), a condensation section (4) of the heat pipe (1) is located outside the inner circulation chamber (6) of the electric cabinet, the evaporation section (3) of the heat pipe (1) is used for collecting heat generated through operation of the heat radiation component (5) and transferring the collected heat to the condensation section (4) outside the circulation chamber in the circulation electrical cabinet (2), and the heat is dissipated from the condensation section (4) of the heat pipe (1) to the atmosphere outside the circulation cabinet (2). The heat radiation method is advantaged in that a heat radiation terminal is separated with an internal circulation back board body, influence of heat radiation on the internal circulation chamber environment is reduced, and stability of operation of a thermal device is improved.

Description

technical field [0001] The invention relates to a heat dissipation method for a circulating electric cabinet. Background technique [0002] In the field of existing heat dissipation technology, heat pipe heat dissipation technology is very mature and common. In fact, the mainstream heat dissipation force in heat dissipation technology has countless applications in the IT industry, industrial power generation, pipeline transportation, and air conditioning. [0003] Nowadays, with the vigorous development of the industry, new requirements are constantly put forward for the use of electric cabinets, and double-cycle electric cabinets have also emerged as the times require. As the internal components of the electric cabinet continue to develop and evolve in the direction of modularization, miniaturization, and high power density. In this case, the traditional electric cabinet backplane radiator (that is, the radiator is installed on the backplane of the electric cabinet) gradua...
