a plurality of vertical radiating fin plates are arranged in the cooling channel, the cooling channel is divided into a plurality of vertical convection channels by the radiating fin plates, and one inward side of each radiating fin plate extends into the shell.

Preferably, the top of the shell is provided with a plurality of top edges extending along the front-back direction of the shell side by side, and the top edges are formed by upward bulges on the top surface of the shell.

Preferably, the shell is a sheet metal shell.

Preferably, the front surface of the shell is provided with a display screen, an adjusting knob and a wiring terminal.

Preferably, the bottom of the housing is provided with a plurality of rubber support feet.

Preferably, the heat dissipation fin plate is an aluminum alloy plate or a copper alloy plate.

The beneficial effects of the utility model are concentrated and are embodied in: on the premise of not additionally arranging electric devices such as a cooling fan and the like, the cooling performance of the equipment is ensured, the power consumption is low, and the energy-saving and environment-friendly effects are achieved. Particularly, the utility model discloses in the use, the shell adopts sealed design, can effectually carry out dustproof protection to the electric elements of inside. One side stretches into the inside heat dissipation finned plate of shell and can derive the inside heat of shell, separates into a plurality of convection current passageways with the cooling channel by many heat dissipation finned plates simultaneously, utilizes the principle of hot-air come-up, and the chimney effect that forms in the convection current passageway can promote the air convection of convection current passageway for heat exchange is carried out with the air to the heat dissipation finned plate can be quick. The utility model discloses compare with traditional increase radiator fan's mode, the power consumption is lower, and can be better carry out dustproof protection to equipment, prevent that electrical component is ageing, have longer life.

Detailed Description

As shown in fig. 1-2, the low power consumption soft switching power supply includes a sealed housing 1 and a soft switching power supply body disposed in the housing 1, wherein a plurality of rubber supporting feet 9 are disposed at the bottom of the housing 1 to support the housing 1 to ensure a ground clearance, and the height of the housing is usually about 2-3 cm. The shell 1 adopts the totally enclosed design, can effectually prevent magazines such as dust from getting into in the shell 1 and causing the pollution to electrical component, realizes dustproof protection, avoids electrical component ageing, its ordinary sheet metal housing that adopts. The soft switching power supply body adopts a soft switching power supply sold in the market, for example: the phase-shift control ZVS full-bridge soft-switching power supply or other types of soft-switching power supplies, etc. will not be described again.

The utility model discloses the biggest difference lies in, the no power heat dissipation of shell 1, and it is also a passive radiating mode in essence, need not to adopt power consumptive heat radiation equipment such as radiator fan, semiconductor cooler. The shell 1 is cuboid, a U-shaped cooling channel 2 is arranged on the outer side of the shell 1, the cooling channel 2 is located on the rear side and the left side and the right side of the shell 1, the cooling channel 2 partially penetrates through the shell 1 along the vertical direction, and the cooling channel 2 on the rear side and the left side and the right side jointly form a U-shaped structure.

A plurality of vertical heat dissipation fins 3 are arranged in the cooling channel 2, the heat dissipation fins 3 are preferably made of a metal material with high cost performance, such as a copper alloy plate, an aluminum alloy plate, and the like, and it is of course possible to use other heat dissipation fins 3 having the same performance. The cooling channel 2 is divided into a plurality of vertical convection channels 4 by the heat dissipation fin plate, and one inward side of the heat dissipation fin plate 3 extends into the shell 1.
