Abstract

A thin heat exchange panel includes a contact side that is in contact with a heat source and a plurality of heat exchange channels disposed in the contact side. A water inlet channel of the heat exchange panel is connected with a high-pressure pump for inputting high-pressure water, and a water outlet channel of the heat exchange panel is connected with a cooler to form a circulating cooling system. When the high-pressure pump is started, the high-pressure water quickly enters the water inlet channel. Reduced control holes communicating with the water inlet channel are configured to regulate the average flow rate and increase the speed of the water to bring a high-speed jet effect, which improves the heat exchange rate of the water in the heat exchange channels to achieve the effects of low damping, high heat dissipation efficiency and thinning.

Claims

1. A thin heat exchange panel, comprising at least one contact side that is in contact with a heat source and a plurality of parallel and upright heat exchange channels disposed in the contact side, two ends of each heat exchange channel communicating with a water inlet channel for inputting high-pressure water and a water outlet channel connected to a cooler respectively, a reduced control hole being disposed between each heat exchange channel and the water inlet channel;

a cross-sectional area of each reduced control hole being added up, which being less than or equal to a cross-sectional area of the water inlet channel, a cross-sectional area of each heat exchange channel being added up, which being less than or equal to a cross-sectional area of the water outlet channel, the cross-sectional area of the water inlet channel being less than the cross-sectional area of the water outlet channel.

2. The thin heat exchange panel as claimed in claim 1, wherein a cone-shaped flared channel is disposed between each reduced control hole and each heat exchange channel.

3. The thin heat exchange panel as claimed in claim 1, wherein the heat exchange panel is formed by combining at least two panel bodies.

4. The thin heat exchange panel as claimed in claim 1, wherein the water inlet channel is connected to a water inlet pipe;

the water outlet channel is connected to a recycling water pipe.

5. The thin heat exchange panel as claimed in claim 1, wherein the cross-sectional area of each reduced control hole is adjustable according to a flow demand.

6. The thin heat exchange panel as claimed in claim 5, wherein the cross-sectional area of each reduced control hole is gradually enlarged from the reduced control hole close to a water inlet end of the water inlet channel to the reduced control hole close to a tail closed end of the water inlet channel.

7. The thin heat exchange panel as claimed in claim 6, wherein the cross-sectional area of each reduced control hole is incrementally set from the water inlet end to the tail closed end.
