Thin heat exchange panel

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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(16) Referring to FIG. 4 to FIG. 7A, the present invention discloses a thin heat exchange panel 100, comprising at least one contact side 10 that is in contact with a heat source and a plurality of parallel and upright heat exchange channels 20 disposed in the contact side 10. Two ends of each heat exchange channel 20 communicate with a water inlet channel 30 for inputting high-pressure water and a water outlet channel 40 connected to a cooler 80, respectively. A reduced control hole 50 is disposed between each heat exchange channel 20 and the water inlet channel 30.

(17) The cross-sectional area of each reduced control hole 50 is added up, which is less than or equal to the cross-sectional area of the water inlet channel 30. The cross-sectional area of each heat exchange channel 20 is added up, which is less than or equal to the cross-sectional area of the water outlet channel 40. The cross-sectional area of the water inlet channel 30 is less than the cross-sectional area of the water outlet channel 40.

(18) With the above structure, the contact side 10 of the heat exchange panel 100 is in contact with the heat source, and the water inlet channel 30 is connected with a high-pressure pump 70 for inputting the high-pressure water, and the water outlet channel 40 is connected with the cooler 80 to form a circulating cooling system 90. When the high-pressure pump 70 is started, the high-pressure water quickly enters the water inlet channel 30. The reduced control hole 50 regulates the average flow rate and increases 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 20 to achieve the effects of low damping, high heat dissipation efficiency and thinning.

(19) Referring to FIG. 8 to FIG. 8B, a cone-shaped flared channel 21 is disposed between each reduced control hole 50 and each heat exchange channel 20. Through the flared channel 21, a dead angle between the reduced control hole 50 and the heat exchange channel 20 is avoided, and the space of each heat exchange channel 20 is used effectively.

(20) Referring to FIG. 5 to FIG. 7, the heat exchange panel 100 is formed by combining at least two panel bodies 1001. In this embodiment, the heat exchange panel 100 is formed by combining three panel bodies 1001. Through the at least two panel bodies 1001, the heat exchange panel can be easily processed and manufactured by sheet metal forming, stamping, or CNC precision milling.

(21) Referring to FIGS. 8A to 9 and FIG. 4, the water inlet channel 30 is connected to a water inlet pipe 32. The high-pressure water from the high-pressure pump 70 is conveyed into the water inlet channel 30 through the water inlet pipe 32. The water outlet channel 40 is connected to a recycling water pipe 42. The cooling liquid after absorbing heat is returned to the cooler 80 through the recycling water pipe 42.

(22) Furthermore, referring to FIG. 8A to FIG. 8B, the cross-sectional area of each reduced control hole 50 can be adjusted according to the flow demand.

(23) Preferably, the cross-sectional area of each reduced control hole 50 is gradually enlarged from the reduced control hole 50 close to a water inlet end 301 of the water inlet channel 30 to the reduced control hole 50 close to a tail closed end 302 of the water inlet channel 30.

(24) Finally, the cross-sectional area of each reduced control hole 50 is incrementally set, a1, a2, a3 to aN, from the water inlet end 301 to the tail closed end 302, thereby avoiding the reduced control holes 50 adjacent to the water inlet end 301 to take away the flow of the reduced control holes 50 adjacent to the tail closed end 302, so as to achieve an average flow rate of the cooling liquid.

(25) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
