Description

Technical Field

[0001] The utility model relates to the technical field of evaporation heat dissipation, in particular to a three-dimensional strong heat exchange evaporation heat pipe radiator. Background Art

[0002] The traditional heat pipe evaporator has a liquid injection cavity for containing freon. The bottom plate of the evaporator is directly in contact with the heat source. Heat is transferred to the freon liquid in the freon liquid injection cavity through the evaporator bottom plate and the fins welded on the bottom plate, and then the heat is taken away through boiling heat transfer. Finally, the heat is transferred to the ambient air through the condensation process occurring in the condenser connected at the far end, so as to achieve evaporation heat dissipation. The traditional heat pipe evaporator adopts a direct evaporation heat dissipation method. However, when the heat density of the heat source is relatively large, such as when the heat flux density is greater than 80 W / cm 2 When it is, most of the environmentally friendly freon will exceed its corresponding evaporation limit, resulting in poor heat dissipation performance and unsatisfactory heat dissipation effect. If a conventional two-dimensional heat pipe is used to solve the problem of high-power density heat transfer limit, since this heat still needs to be transferred by the traditional evaporator, the temperature rise generated by the entire evaporator is also worse than that of the conventional heat pipe radiator.

[0003] Therefore, how to propose a heat pipe evaporator that can ensure good heat dissipation performance under high power and high density is a technical problem that needs to be solved urgently at present. Summary of the Utility Model

[0032] Embodiment 1:

[0033] The present utility model provides a three-dimensional strong heat exchange evaporation heat pipe radiator 10, as Figures 1 to 3As shown in the figure, the three-dimensional forced convection evaporation heat pipe radiator 10 includes a three-dimensional temperature equalizing component 100, a heat dissipation structure 200, and an evaporation housing 300. Among them, the three-dimensional temperature equalizing component 100 includes a first housing 110, a second housing 120, and a capillary layer 130. The second housing 120 includes a flat bottom 121 and a convex tube portion 122. The flat bottom 121 covers the opening of the first housing 110. The lumen of the convex tube portion 122 communicates with the cavity of the first housing 110 to form a first chamber 101. The capillary layer 130 is disposed on the inner wall surface of the first chamber 101. The capillary layer 130 is not only disposed on the inner wall surface of the first housing 110, but also disposed on the inner wall surface of the second housing 120. The first chamber 101 is used to fill the working fluid, and the capillary layer 130 is used to accelerate the transfer of the working fluid in the first chamber 101. The heat dissipation structure 200 is disposed on the outer wall surface of the second housing 120, and the heat dissipation structure 200 is used to accelerate the heat transfer rate. The evaporation housing 300 covers the outside of the second housing 120. A second chamber 102 is formed between the evaporation housing 300 and the second housing 120. The convex tube portion 122 and the heat dissipation structure 200 are both disposed in the second chamber 102. The heat dissipation fluid flows through the second chamber 102 to take away heat.

[0034] The three-dimensional forced convection evaporation heat pipe radiator 10 forms two different and nested chambers through the nested three-dimensional temperature equalizing component 100 and evaporation housing 300. The first chamber 101 is a vacuum chamber filled with the working fluid, and the working fluid is generally pure water. After the first housing 110 contacts the heat source, the heat of the heat source is transferred into the first chamber 101, causing the pure water to vaporize and absorb heat. The vaporized gas moves into the lumen of the second housing 120 and releases heat and liquefies in the lumen of the convex tube portion 122. The liquefied pure water can quickly flow back to the first housing 110 through the capillary layer 130 to exchange heat with the heat source again; the second chamber is a flow chamber through which the heat dissipation fluid flows. The heat dissipation fluid can be selected as Freon. When Freon flows through the second chamber 102, it exchanges heat with the working fluid in the first chamber through the second housing 120. After Freon absorbs heat, it flows out of the second chamber 102, and finally takes away the heat generated by the heat source. The nested arrangement of the first chamber 101 and the second chamber 102 helps to increase the heat conduction amount and the heat conduction rate.

[0035] Compared with the conventional two-dimensional heat pipe, the three-dimensional temperature equalizing component 100 has an advantage in height. It can not only provide more three-dimensional VC (Vapor Chamber) condensation area, but also provide more evaporation area for the three-dimensional forced convection evaporation heat pipe radiator 10, greatly reducing the heat transfer resistance between the three-dimensional temperature equalizing component 100 and the heat pipe. It not only solves the problem of the failure of the conventional heat pipe radiator, but also solves the heat dissipation problem of higher power density, and can meet the heat dissipation requirements under high power density. And through experiments, it is obtained that: compared with the traditional heat pipe radiator, the three-dimensional forced convection evaporation heat pipe radiator 10 provided by the embodiment of the present invention can reduce the thermal resistance by about 25%.

[0036] Optionally, both the first housing 110 and the second housing 120 are metal housings, and the metal housing has a high heat transfer efficiency. The materials for making the first housing 110 and the second housing 120 may be the same or different.

[0037] Continue to refer to Figure 3 As shown, a support structure is provided inside the first housing 110. The support structure is used to support the flat bottom 121, and a capillary layer 130 is wrapped on the outer wall surface of the support structure. The support structure can not only improve the support stability for the second housing 120, but also increase the area of the capillary layer 130, which helps to further improve the rate of the working fluid flowing back to the vicinity of the heat source. It should be noted that the support structure and the first housing 110 may be integrally formed or separately manufactured and then welded together.

[0038] Optionally, the support structure includes support columns 140. The bottom ends of the support columns 140 are connected to the bottom surface of the first housing 110, and the top ends of the support columns 140 are flush with the top surface of the first housing 110.

[0041] Continue to refer to Figure 3 As shown, in some embodiments, the first housing 110 includes a first housing portion 111 and a second housing portion 112 that are connected in a stepped manner. The opening area of the first housing portion 111 is smaller than the opening area of the second housing portion 112.

Optionally, the first bottom plate is a rectangular plate, and the first annular plate is composed of four rectangular first side plates.

Optionally, the annular bottom plate is a rectangular annular plate, and the second annular plate is composed of four rectangular second side plates. The second side plates protrude upward from the outer wall surface of the annular bottom plate. It should be noted that the outer shape of the first housing portion 111 and the outer shape of the second housing portion 112 may be the same or different. For example, when the first housing portion 111 is a cubic-shaped housing, the second housing portion 112 may be a cubic-shaped housing or a cylindrical housing.

[0043] The support columns 140 provided in the first housing 110 have different heights according to their installation positions. When the first housing 110 only includes the first housing portion 111 and the second housing portion 112 that are connected in a stepped manner, the support columns 140 are divided into two parts according to their installation positions. One part is provided on the first bottom surface of the first housing portion 111, and the other part is provided on the annular second bottom surface of the second housing portion 112. Among them, the height of the support column 140 provided on the first bottom surface is higher than the height of the support column 140 provided on the second bottom surface.

[0044] Continue to refer to Figure 1 As shown, the housing opening of the first housing 110 is a rectangular opening, and the outer shape of the flat bottom portion 121 of the second housing 120 is a rectangular plate.

[0047] Continue to refer to Figure 1 As shown, the convex tube portion 122 is a round tube. Of course, in other embodiments, the convex tube portion 122 can also be a tube body of other shapes, such as a square tube, a flat tube, etc.

[0048] Optionally, a plurality of convex tube portions 122 are provided, and the plurality of convex tube portions 122 are arranged in rows and columns. In one embodiment, 25 convex tube portions 122 are provided and arranged in five rows and five columns.

[0049] Optionally, the convex tube portion 122 is a copper tube. The copper tube has good heat conduction performance and can improve the heat exchange efficiency between the first chamber 101 and the second chamber 102.

[0050] The heat dissipation structure 200 can further strengthen heat exchange by increasing the heat exchange area with the refrigerant in the second chamber 102. Continuing to refer to Figure 1 and Figure 3 As shown, the heat dissipation structure 200 includes heat dissipation fins 210, and the heat dissipation fins 210 are sleeved on the convex tube portion 122.

The shape of the through holes 211 is the same as the cross-sectional shape of the convex tube portion 122. Such a setting can achieve the plug-in fit of one heat dissipation fin 210 with all the convex tube portions 122, which helps to improve the processing efficiency. It should be noted that after the convex tube portion 122 passes through the through holes 211, the heat dissipation fins 210 can be welded to the convex tube portion 122. In one embodiment, each heat dissipation fin 210 is provided with 25 circular through holes 211, and the 25 through holes 211 are arranged in five rows and five columns. Of course, in other embodiments, a heat dissipation structure can also be provided separately on each convex tube portion 122.

[0052] Optionally, the heat dissipation fins 210 are rectangular sheets.

[0053] Continuing to refer to Figure 1 As shown, the evaporation housing 300 is provided with a liquid injection pipe orifice 301, an evaporation pipe orifice 302, and a reflux pipe orifice 303 that communicate with the first chamber 101. In some embodiments, the evaporation housing 300 includes a covering body 310, a liquid inlet pipe 320, an evaporation pipe 330, and a reflux pipe 340.
