Water-cooling heat dissipation electromagnetic heating device and control method thereof

Abstract

The invention provides a water-cooling heat dissipation electromagnetic heating device. The water-cooling heat dissipation electromagnetic heating device comprises an electromagnetic heating induction coil, a water storage tank and a cooling pump. A water flow channel in the electromagnetic heating induction coil is connected with the water storage tank through the cooling pump so that water circulation exchange between the electromagnetic heating induction coil and the water storage tank can be achieved. A water temperature detecting device, a water level detecting device, a water inlet device, a spillway and a water circulation control module are arranged on the water storage tank. The water-cooling heat dissipation electromagnetic heating device is characterized in that when the water temperature detecting device detects that the temperature in the water storage tank is higher than the spillway temperature, the water circulation control module starts the water inlet device for water inflow, and therefore the temperature in the water storage tank is lowered.

Fault

However, in the existing water cooling system, the distance between the heat dissipation water pan and the electromagnetic heating coil is often too large, and it is difficult to fully fit, thus affecting the heat dissipation effect

In addition, thermal conductive silicone grease is often used in the prior art, because metal powder is added to it, so its insulation performance is poor, and thermal conductive silicone grease is easy to dry and fall off, making it difficult to ensure a tight fit between the heat dissipation water pan and the electromagnetic heating coil , making it difficult to ensure thermal performance

In addition, the heat pipes in the prior art often use hard pipes, which are difficult to bend, have large diameters, and take up a lot of space

Obviously, it is difficult to fully dissipate heat by using a closed circulation system, and as described below, it will cause scaling and algae problems, and seriously block the water circulation pipeline, resulting in damage to the electromagnetic heating device

[0007] 3. Water scaling and algae in the water cooling system of the electromagnetic heating device

Since the water-cooled heat dissipation system in the prior art often adopts a closed circulation system, scale and algae may appear after long-term use, which will affect the work of the water-cooled heat dissipation system

[0008] Obviously, the heat dissipation system of the electromagnetic heating device in the prior art has a technical bottleneck of poor heat conduction and poor heat discharge; in addition, the electromagnetic heating device in the prior art mentioned above is difficult to solve the technical problem of precise temperature control
