Description

A kind of heat-pipe radiator

Technical field

The utility model belongs to radiator field, specifically refers to a kind of heat-pipe radiator.

Background technology

At present, radiator is widely used in dispelling the heat to electronic device, to reduce the temperature of electronic device, keep the normal operation of electronic device, therefore the quality of its heat radiation is related to the quality of life of product and computing, and normally used radiator, be mainly provided with a metal (being aluminium mostly) heat-radiating substrate, its top (with extruding or casting) is provided with several grooves and column fin, makes columnar structures have preferably cooling surface area; A fan is folded with again above this fin, make fan can brush heat radiation facing to radiating fin, be provided with the heat pipe of connection between current heat radiator body and radiating fin more, current heat pipe entirety is in three sections, and wherein end section is arranged in heat-radiating substrate, horizontally set, stage casing passes from radiator, expose in atmosphere, top section is arranged in radiating fin, and this structural design heat transfer efficiency is lower.

Utility model content

The utility model, in order to overcome the deficiency of prior art, proposes the heat-pipe radiator that a kind of heat transfer efficiency is high.

The utility model solves above-mentioned technical problem by following technical proposals.

A kind of heat-pipe radiator, comprise the substrate contacted with thermal source and four radiating fin arrays being arranged on surface, be connected by heat pipe between described substrate with four radiating fin arrays, described radiating fin array by multiple in be horizontally disposed with and the rectangular heat dissipation fin that interval is evenly arranged above and below forms, identical cuboid sized by described four radiating fin arrays and the horizontal cross section of four radiating fin arrays is arranged in four quadrants of horizontal plane respectively, any two X-axis about four quadrants in described four radiating fin arrays or Y-axis or central point, connected by heat pipe between two radiating fin arrays in adjacent quadrants, the heat pipe being positioned at X-axis both sides quadrant is that heat pipe closed by first of common contiguous base substrate, the heat pipe being positioned at Y-axis both sides quadrant is that second of common connection substrate closes heat pipe, described first closed heat pipe and second is closed heat pipe and is had orthogonal endotherm section in substrate inside, described first closed heat pipe and second is closed heat pipe and is had the heat release section wearing four radiating fin arrays, described first closes heat pipe and second closes heat pipe and includes two and be parallel to each other and the respective U-shaped heat pipe that is connected of heat release section top.

More specifically, equal spacing is left between described any two adjacent radiating fin arrays.

More specifically, the single rectangular heat dissipation fin of described formation four radiating fin arrays is square.

More specifically, the described square length of side is 1 ~ 10cm.

More specifically, the diameter of described heat pipe is 0.3 ~ 1cm.

The beneficial effects of the utility model are, the utility model, by arranging four rectangular-shaped radiating fin arrays and interconnective heat pipe in surface, makes area of dissipation greatly increase, significantly improves heat transfer efficiency.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 is front view of the present utility model.

Embodiment

The utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.

As Fig. 1 to Fig. 2, the present embodiment comprises the substrate 1 contacted with thermal source and four radiating fin arrays 2 be arranged on above substrate 1, be connected by heat pipe 3 between described substrate 1 with four radiating fin arrays 2, described radiating fin array 2 by multiple in be horizontally disposed with and the rectangular heat dissipation fin that interval is evenly arranged above and below forms, identical cuboid sized by described four radiating fin arrays 2 and horizontal cross section of four radiating fin arrays 2 is arranged in four quadrants of horizontal plane respectively, any two X-axis about four quadrants in described four radiating fin arrays 2 or Y-axis or central point O symmetrical, connected by heat pipe 3 between two radiating fin arrays 2 in adjacent quadrants, be positioned at the heat pipe (32 of X-axis both sides quadrant, 32 ') for heat pipe closed by first of common contiguous base substrate 1, be positioned at the heat pipe (31 of Y-axis both sides quadrant, 31 ') for second of common connection substrate 1 closes heat pipe, described first closes heat pipe (32, 32 ') heat pipe (31 is closed with second, 31 ') in substrate 1 inside, there is orthogonal endotherm section, described first closes heat pipe (32, 32 ') heat pipe (31 is closed with second, 31 ') there is the heat release section wearing four radiating fin arrays 2, described first closes heat pipe (32, 32 ') heat pipe (31 is closed with second, 31 ') include two to be parallel to each other and the U-shaped heat pipe that heat release section top is connected separately.

Equal spacing is left between described any two adjacent radiating fin arrays 2.

The single rectangular heat dissipation fin of described composition four radiating fin arrays 2 is square.

The described square length of side is 5cm.

The diameter of described heat pipe is 0.5cm

Due to substrate 1 be provided with four in hard Nogata to arrange radiating fin array 2 and heat pipe 3, considerably increase area of dissipation, improve heat transfer efficiency.

Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
