Abstract
This utility model relates to a kind of heat sink in heat-transfer technology field, include the heat sink body of hollow, described heat sink body upper surface is provided with the square tube along heat sink body length direction, fit with heat sink body upper surface in the bottom surface of described square tube, the heat conduction fin of hollow is installed on the heat sink upper surface of described square tube both sides, fit with heat sink body upper surface in the bottom surface of heat conduction fin, described square tube is connected with heat conduction fin, is perfused with working media in the hollow structure of described heat sink body.Existence due to working media, heat can be rapidly transferred on heat sink body, again due to the existence of square tube, heat on heat sink can be discharged rapidly by condensed fluid, simultaneously because the existence of heat conduction fin, a part of heat is discharged by heat conduction fin itself, and the heat in heat sink is also taken away by the condensed fluid flow through in heat conduction fin, thus reaches the purpose of local radiating and cooling.This device can use as heat sink, and it is safe and reliable.
Description
Technical field
This utility model relates to a kind of heat-transfer arrangement, particularly to a kind of heat sink.
Background technology
Disclosing the heat sink of a kind of good heat conduction effect in existing Chinese patent database, its number of patent application is:
201420209158.5, filing date: 2014.04.28, notification number is: CN203859973U, and the day for announcing is: 2014.10.01,
Its structure includes: hollow heat sink, and the zone line of heat sink is the thermal treatment zone, and exterior lateral area is radiating area, and feature is heat radiation
The inner face of the thermal treatment zone of plate is provided with fine-meshed metal net, and the inner face of the radiating area of heat sink is provided with coarse-meshed wire gauze, fine-meshed metal net
Or coarse-meshed wire gauze is all fixed on heat sink inner face by sintering processing.It is disadvantageous in that: due to this device the most only
It is to have employed the hollow structure of heat sink body to coordinate fine-meshed metal net or coarse-meshed wire gauze to carry out local to dispel the heat.
Utility model content
This utility model solves the technical problem that and is: on the basis of drawing and absorbing existing heat sink technology, it is provided that one
Planting new heat sink, this heat sink absorbs rapidly the amount of localized heat of near heating sources, then by flowing in square tube and heat conduction fin
Condensed fluid by heat discharge, it is ensured that heat sink works effectively.
In order to realize the purpose of above-mentioned utility model, technical solution adopted in the utility model:
A kind of heat sink, includes the heat sink body of hollow, and described heat sink body upper surface is provided with along heat sink
The square tube in body length direction, the bottom surface of described square tube and the laminating of heat sink body upper surface, the heat sink of described square tube both sides
Being provided with the heat conduction fin of hollow on upper surface, fits with heat sink body upper surface in the bottom surface of heat conduction fin, described square tube with
Heat conduction fin is connected, and is perfused with working media in the hollow structure of described heat sink body.
During utility model works, heat sink body lower surface absorbs the heat of thermal source, thus heat is delivered to heat sink
On intrinsic working media, then condensed fluid flows into square tube and heat conduction fin, and condensed fluid absorbs heat, and last condensed fluid will dissipate
Heat on hot plate is taken away, and condensed fluid flows out in square tube and heat conduction fin.Compared with prior art, of the present utility model useful
Effect is: due to the existence of working media, and heat can be rapidly transferred on heat sink body, again due to the existence of square tube,
Heat on heat sink can be discharged rapidly by condensed fluid, simultaneously because the existence of heat conduction fin, heat conduction fin itself is by a part
Heat is discharged, and the heat in heat sink is also taken away by the condensed fluid flow through in heat conduction fin, thus reaches local radiating and cooling
Purpose.This device can use as heat sink, and it is safe and reliable.
In order to accelerate the speed of heat transfer, described heat sink body, square tube, the outer surface of heat conduction fin pass through sintering
Mode is fixed with alloy bronze powder.
In order to make condensed fluid circulate in heat conduction fin, described square tube is connected through flexible pipe with heat conduction fin.
It is connected to water inlet pipe and outlet pipe in square Bottomhole pressure, described square tube two ends for the ease of condensed water.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 heat sink body, 2 square tubes, 3 flexible pipes, 4 heat conduction fins, 5 water inlet pipes, 6 outlet pipes.
Detailed description of the invention
This utility model is not limited to embodiment, on the basis of technical scheme disclosed in this utility model, and this area
Technical staff according to disclosed technology contents, it is not necessary to some of which technical characteristic just can be made by performing creative labour
Going out some to replace and deformation, these are replaced and deformation is all in protection domain of the present utility model.
As it is shown in figure 1, a kind of heat sink, including the heat sink body 1 of hollow, heat sink body 1 upper surface is provided with
Along the square tube 2 of heat sink body 1 length direction, flowing in square tube 2 for the ease of condensed water, square tube 2 two ends connects respectively
Water inlet pipe 5 and outlet pipe 6, the bottom surface of square tube 2 is had to fit with heat sink body 1 upper surface, the heat sink upper surface of square tube 2 both sides
On the heat conduction fin 4 of hollow is installed, fit with heat sink body 1 upper surface in the bottom surface of heat conduction fin 4, in order to make condensed fluid exist
Circulation in heat conduction fin 4, square tube 2 is connected through flexible pipe 3 with heat conduction fin 4, is perfused with work in the hollow structure of heat sink body 1
Medium, in order to accelerate the speed of heat transfer, heat sink body 1, square tube 2, the outer surface of heat conduction fin 4 pass through sintering processing
It is fixed with alloy bronze powder.
During work, heat sink body 1 lower surface absorbs the heat of thermal source, thus heat is delivered in heat sink body 1
On working media, then condensed fluid flows into square tube 2 through water inlet pipe 5, and the condensed fluid in square tube 2 flows into heat conduction fin 4 through flexible pipe 3
In, then the condensed fluid in heat conduction fin 4 is in flexible pipe 3 flows to square tube 2 again, and the condensed fluid in square tube 2 absorbs heat, the coldest
Heat on heat sink is taken away by lime set, and condensed fluid flows out from the outlet pipe 6 of square tube 2.
