Heat dissipation device using an external air source

Abstract

The invention discloses a heat dissipation device using an external air source. Include a heat dissipation substrate, sealing gasket, heat dissipation fin plat, Six mounting screws, outlet fitting, Plug, muffler, Intake connection, the heat dissipation device uses compressed air supplied from an external air source as an enhanced heat transfer medium, Introduce compressed air from the intake fitting, through the air passage between the heat dissipation substrate and the heat dissipation fin plate, the air passage is discharged from the air outlet connector or the muffler, As that compress airflows in the air passage between the heat dissipation substrate and the heat dissipation fin, heat exchange occurs with the radiator, and carrying heat out of the radiator, so as to achieve the purpose of improving the heat dissipation effect, By installing the air outlet connector, the plug and the muffler on the air outlet of the heat dissipation substrate in different combinations, the heat dissipation device can realize the switching of the natural heat dissipation mode, the normal mode and the air bypass mode, and the invention is particularly suitable for the heat dissipation of the electronic drive control system of the equipment which needs an external air source to operate.

Description

technical field [0001] The invention relates to the field of industrial control equipment, in particular to a radiator and a radiator. Background technique [0002] Electronic control drive equipment is the core of modern industrial control equipment. Any electronic control drive equipment is faced with the problem of heat generation and heat dissipation. Therefore, heat dissipation devices have become an indispensable part of electronic control drive equipment. Heat sinks can generally be divided into natural convection heat sinks and forced convection heat sinks. Natural convection heat sinks dissipate heat through convective motion caused by temperature-induced changes in gas density. The structure is relatively simple and reliable. The heat dissipation area can meet the heat dissipation requirements. With the development trend of integration and miniaturization of industrial control equipment, natural convection cooling devices have been difficult to meet the increasing...

Problems solved by technology

The heat exchange efficiency of the forced convection heat exchange device is relatively high, but there are also the following disadvantages: 1. The forced convection heat exchange requires additional components such as fans, which makes the heat dissipation device larger and more complicated; 2. The heat dissipation fan becomes a heat dissipation device Once it fails, the heat dissipation performance of the cooling device will drop sharply, endangering the operation of the equipment; 3. The forced convection cooling device needs to open ventilation holes on the product shell to ensure air circulation. The existence of ventilation holes makes it easy for small debris to enter The interior of the electronic product leads to failure
