Description

A kind of spiral thermal siphon loop heat pipe radiator

Technical field

The utility model relates to a kind of spiral thermal siphon loop heat pipe radiator, belongs to heat radiation cooling-part field, is applicable to the heat radiation of various electronic devices and thermoelectric cooling module.

Background technology

Along with the high speed development and the thermoelectric cooling broad application of electronic technology, various heat dissipation technologys are synchronized development thereupon also.Present various radiators mainly adopt the mode of fan forced air cooling, and for requiring the quiet situation that maybe should not adopt fan, need to adopt the free convection mode to cool off, its heat transfer property of silk screen radiator of present more employing is not high, the requirement area of dissipation is big, thereby brings weight and the big shortcoming of consumptive material.

Summary of the invention

The purpose of this utility model is to propose a kind of spiral thermal siphon loop heat pipe radiator, to overcome the shortcoming in the prior art, to improve the heat transfer property of radiator, weight reduction, save consumable material, and make the manufacturing process of radiator simple, reduce equipment cost.

The spiral thermal siphon loop heat pipe radiator that the utility model proposes comprises evaporimeter and condenser, and described evaporimeter is in the bottom of radiator, and condenser is in the top of radiator; Described condenser is made up of runner pipe and fin, runner pipe and fin are formed by the sheet material extruding, the upper end of described condenser runner pipe links to each other with upper end of evaporator by vapor uptake, and the lower end of condenser runner pipe links to each other with the lower end of evaporimeter by liquid return tube.

The spiral thermal siphon loop heat pipe radiator that the utility model proposes, its advantage is:

1, whole heat-pipe radiator is a loop heat pipe system, and inside is evaporation and condensation heat transfer, and system temperature is even, so the heat dispersion height;

2, the condenser in the heat-pipe radiator is by the moulding of spiraling of aluminium fin and runner pipe, and the aluminium fin is thin and light, is again whole rolling forming, therefore, and the light weight of radiator and good heat-transfer;

3, whole heat-pipe radiator radiator has only two connectors altogether, and processing is simple, sealing system reliability height;

4, consumable material is few, and equipment manufacturing cost is low.

Among Fig. 1, the 1st, evaporimeter, the 2nd, condenser, 2-1 are runner pipes, 2-2 is a fin, the 3rd, vapor uptake, the 4th, liquid return tube.

The specific embodiment

The spiral thermal siphon loop heat pipe radiator that the utility model proposes, its structure comprises evaporimeter 1 and condenser 2 as shown in Figure 1.Evaporimeter 1 is in the bottom of radiator, and condenser 2 is in the top of radiator.Condenser 2 is made up of runner pipe 2-1 and fin 2-2, and as shown in Figure 2, runner pipe 2-1 and fin 2-2 are formed by the sheet material extruding.The upper end of condenser runner pipe 2-1 links to each other with the upper end of evaporimeter 1 by vapor uptake 3, and the lower end of condenser runner pipe 2-2 links to each other with the lower end of evaporimeter 1 by liquid return tube 4.

The spiral thermal siphon loop heat pipe radiator that the utility model proposes, its operation principle is: entire radiator is a thermal siphon loop heat pipe system, form a sealing system by condenser, vapor uptake and liquid return tube that planar type, spiral aluminum finned tube constitute, after inside vacuumizes, be filled with a certain amount of working medium such as ammonia, freon or acetone etc., again with its sealing.The hot side of electronic device or thermoelectric cooling module is close on the planar type, heat is passed to the liquid refrigerant of evaporimeter inside, working medium heat absorption evaporation, steam enters in the spiral aluminum finned tube of condenser by vapor uptake, steam is at in-tube condensation and emit heat, and heat looses in atmospheric environment by fin, the liquid of in-tube condensation, under the gravity effect, get back to evaporimeter, continue the heat absorption circulation by liquid return tube.The aluminum finned tube of condenser is whole rolling, and pipe is thinner, and fin is very thin, is easy to turn to the condenser of spiral, its two ends pipe can also be prolonged, and as vapor uptake and liquid return tube, the three is integral, and reduces processing capacity and joint.Planar type inside is a cavity of being made up of passage, and vias inner walls has the conduit of augmentation of heat transfer, and the interface that is communicated with vapor uptake and liquid return tube is arranged on the evaporimeter, forms a system with condenser.

Shown in Figure 1 is structure of the present utility model, by the spiral condenser 2 of moulding of aluminum finned tube is the vitals of this radiator, and the thickness of aluminium fin 2-2 can be less than 1mm, whole rolling the forming of runner pipe 2-1 and fin 2-2, so, do not have thermal contact resistance between runner pipe and fin.The pipeline at condenser two ends is prolonged, be used separately as vapor uptake 3 and liquid return tube 4, and make three parts integrators.The lower end of vapor uptake 3 and liquid return tube 4 links to each other with planar type 1, and there is pipeline shape cavity planar type 1 inside, and cavity and vapor uptake 3 and liquid return tube 4 UNICOMs form a sealing system.After whole system vacuumizes, fill, behind system sealing, constitute spiral thermal siphon loop heat pipe radiator with certain liquid refrigerant such as ammonia.

Below introduce the course of work of spiral thermal siphon loop heat pipe radiator: will need the electronic device that dispels the heat or the hot side of thermoelectric cooling module to be close on the planar type 1, its heat is passed to the liquid refrigerant of evaporimeter inside, working medium heat absorption evaporation, steam enters in the spiral aluminum finned tube of condenser 2 by vapor uptake 3, steam condensation and emit heat in runner pipe 2-1, heat looses in atmospheric environment by the aluminium fin, the liquid of in-tube condensation, under the gravity effect, flow back into evaporimeter 1, continue the heat absorption circulation by liquid return tube 4.Owing to circulate with weight-driven working medium, require planar type 1 to be lower than condenser 2, and structurally guarantee to have only in the vapor uptake steam by with the liquid down-comer in can only have liquid to pass through, just the loop heat pipe system is normally moved.

The evaporimeter that uses in this radiator is for can planar type, and can select model for use is LPM-470, the planar type of being produced by Suzhou azure water thermal hardware Co., Ltd.

In this radiator, the aluminum finned tube of forming the spiral condenser can have difformity, and the passage of planar type internal cavity also has different shapes, all belongs to the utility model scope.
