Abstract

The invention discloses a heat dissipating device with independent air channels, which comprises a framework and an air blower unit. The device is characterized in that the framework comprises side walls and a bottom fixing plate, at least two groups of independent air channels in parallel with the side walls are arranged inside the framework, each air channel comprises at least one group of heat dissipating piece group, a baffle I and a baffle II are fixed on the two sides of the heat dissipating piece group, a baffle III and a baffle VI are fixed on the upper and lower end of the heat dissipating piece group, fixing grooves matched with the thickness of the baffle III and the baffle VI are formed in the upper and lower end of one side corresponding to a heat dissipating piece I and a heat dissipating piece II, the baffle III and the baffle VI are fixed at the upper and lower end of the heat dissipating piece group through the fixing grooves, and the framework further comprises side walls and a baffle V used for fixing the heat dissipating piece group; and the air blower unit is fixed at the upper end of the framework. According to the device provided by the invention, an upper air draft and lower air inlet heat dissipation mode is adopted, and the heat is dissipated through the sealed independent heat dissipating channels formed by additional arranging baffles on the circumference of the heating power unit, the structure is stable, the practicability is strong, and the heat dissipating effect is obvious.

Description

technical field [0001] The invention belongs to the field of heat dissipation of heating power units, in particular to a heat dissipation device with an independent air duct. Background technique [0002] For the heat dissipation of high-power equipment, the main power unit is radiated by blowing under the blower and cooling fins. The cold air is blown in from the bottom by the fan, passes through multiple power units and heat sinks, and then is discharged from the air outlet on the top. This cooling method has the following problems: 1. When blowing from the bottom, the upper exhaust will inevitably lead to the top of the power components. There may be ash entering, which affects the heat dissipation effect. In special working conditions, there may be conductive medium dust entering, which poses a safety hazard; 2. Since there is no independent airtight air duct, the cold air will escape from multiple directions after blowing in, and cannot Fully passing through the surfac...

Problems solved by technology

The cold air is blown in from the bottom by the fan, passes through multiple power units and heat sinks, and is discharged from the air outlet on the top. This heat dissipation method has the following problems: 1. If the air is blown from the bottom, the upper exhaust will inevitably lead to the top of the power components. Some of them have falling dust, which affects the heat dissipation effect. In special working conditions, there may be conductive medium dust entering, which poses a safety hazard; 2. Since there is no independent closed air duct, the cold wind will escape from multiple directions after blowing in, so it cannot Fully pass through the surface of the radiator, and the wind speed and pressure will be reduced, which cannot achieve a good heat dissipation effect for the radiator

At present, there are still methods such as liquid cooling, but its structure is complex, the cost is high, and the applicability to high-power equipment is poor.
