Abstract

The utility model relates to a natural convection type and thermal radiation type heat pipe radiator, which comprises a copper pipe, working fluid and fins; the working fluid is placed in the closed copper pipe, one end of the copper pipe is welded with metallic fins through adopting an ultrasonic welding way, the surfaces of both sides of the metallic fin or one surface is provided with black coating. The natural convection type and thermal radiation type heat pipe radiator has simple structure, does not need additional energy consumption, and can radiate a lot of heat through the natural convection and radiation way.

Description

Free convection and heat loss through radiation type heat-pipe radiator
Technical field
The utility model relates to a kind of heat-pipe radiator, particularly a kind of outwards heat-pipe radiator of heat radiation of free convection and radiation mode that utilizes.
Background technology
In the place that electronic equipments such as computer floor, communication station are concentrated, the caloric value of various device is very big.For guaranteeing the operate as normal of electronic equipment, understand the temperature that the small-sized air-conditioner of these local installations reduces its working environment usually.As time goes on, the performance of air-conditioner can descend gradually, and the temperature of machine room just can not be guaranteed sometimes, especially in extremely hot summer.Therefore under non-stop-machine situation, promote the refrigerating capacity of air-conditioner as how minimum cost, guarantee that the operating temperature of machine room becomes a difficult problem.
The utility model content
The purpose of this utility model is exactly that provide for the above-mentioned defective that solves prior art a kind of do not need additive decrementation energy, good heat dissipation effect, free convection and heat loss through radiation type heat-pipe radiator simple in structure, easy for installation.
The purpose of this utility model can realize by following technical solution:
A kind of free convection and heat loss through radiation type heat-pipe radiator are made up of copper pipe, working medium and fin, and working medium places in the airtight copper pipe, and methods such as the end employing ultrasonic bonding of copper pipe are welded with fin.
The purpose of this utility model can be come further accomplished by following technology solution:
Aforesaid free convection and heat loss through radiation type heat-pipe radiator, only in the one or both sides of copper pipe along the metal fin of copper pipe length direction welding a slice or two rectangles, the both side surface of metal fin or wherein one side the coating of black can be arranged.The former helps the free convection of air, and the latter can strengthen the heat loss through radiation of fin.
Aforesaid free convection and heat loss through radiation type heat-pipe radiator, its copper pipe are welded with an end of fin and the other end linearly or 90 degree right-angle bendings, and can be crooked arbitrarily between 0~90 degree.This helps on-the-spot installation.
Working medium in aforesaid free convection and the heat loss through radiation type heat-pipe radiator, copper pipe adopts low-boiling point liquid, can be freon, alcohol, methyl alcohol and acetone etc.
The utility model is simple in structure, and is easy for installation, do not need other consumed energy, can outwards distribute a large amount of heats by the mode of free convection and radiation.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model is made up of copper pipe 1, fin 2 and working medium 3.Working medium 3 places in the airtight copper pipe 1, and methods such as the end employing ultrasonic bonding of copper pipe 1 are welded with fin 2.The material of fin 2 is a metal, can be copper or aluminium fin, and only in the one or both sides of copper pipe 1 along the metal fin of copper pipe length direction welding a slice or two rectangles, the both side surface of metal fin or wherein one side the coating of black can be arranged.The former helps the free convection of air, and the latter can strengthen the heat loss through radiation of fin.Fin 2 can be slotted with further enhancing radiating effect on vertical or horizontal direction.The end that copper pipe 1 is welded with fin be fin end (also claiming condensation segment) with the other end (plain end also claims bringing-up section) linearly or 90 degree right-angle bendings, and can be crooked arbitrarily between 0~90 degree.This helps on-the-spot installation.Working medium 3 in the copper pipe 1 adopts low-boiling point liquid, can be freon, alcohol, methyl alcohol and acetone etc.Copper pipe 1 inwall and bottom can be smooth, also can post capillary wick.Capillary wick can be a kind of in groove, fine copper silk screen, fine copper fibre bundle and the spring of inside pipe wall or the structure such as metal powder sintered or several combination.The shape of copper pipe 1 can be circle, ellipse or pancake.
The course of work of the present utility model is: working medium 3 is that bringing-up section absorbs heat of vaporization at the plain end of copper pipe 1, the fin end that steam flows to copper pipe 1 is mode outwards heat radiation and the condensation of condensation segment with free convection and radiation, be back to bringing-up section by the liquid sucting core structure in gravity or the copper pipe 1 again, so move in circles, constantly heat is carried and distributed from the hot junction to cold junction.Be optimized in conjunction with thermal conduction study and hydrodynamics length ratio, fin size and structure, thereby guarantee to carry fast and distribute a large amount of heats pipe diameter of the present utility model and two sections.

Claims (4)
