Abstract
The utility model relates to a multilayer mesh structured looped heat pipe radiator, which belongs to the field of cooling components of electronic devices. The looped heat pipe radiator comprises an evaporator and a condenser, wherein the condenser consists of a condenser pipeline and a reinforcing radiating mesh welded onto the condenser pipeline. One end of the condenser pipeline in spiral shape is connected with a steam outlet of the evaporator, and the other end is connected with a liquid return pipe opening of the evaporator. The looped heat pipe radiator has the advantages that total pipeline joints in the whole radiator are greatly reduced, thereby leakage possibility is reduced, reliability of heat pipes and product yield are guaranteed, a complicated five-way connector is omitted, further, since the steam pipe opening and the condensing liquid return opening are directly welded with the evaporator, processing and material cost are reduced, the flow state is improved, temperature evenness of the whole heat pipe is increased, while radiation efficiency is increased, and the radiator is reasonable and simple in structure and beautiful in appearance.
Description
Technical field
The utility model relates to a kind of loop heat pipe radiator of multi-layer silk screen structure, belongs to dissipation from electronic devices cooling-part field.
Background technology
Along with the high speed development of electronic technology, the heat radiation of various electronic devices cooling has become outstanding and important problem.The heat radiation in its hot junction has determined refrigerating efficiency in the semi-conductor electricity Refrigeration Technique.Present semiconductor electronic refrigerator has much adopted the technology of heat pipe and the combination of silk screen radiator.In order to adapt to radiating requirements, once developed four layers of screen type heat-pipe radiator, but its steam mouth of pipe and the condensate liquid backflow mouth of pipe are a lot, can not directly be connected with evaporimeter, be connected with the evaporation end-apparatus after needing five-way joint by two complexity pool two mouths.Therefore, soldering tip is many, and not only artificial the and material cost height of welding also makes disqualification rate and leak rate increase greatly, causes the price of radiator higher, has directly influenced the development of electronic refrigerator.
Summary of the invention
The purpose of this utility model is to propose a kind of loop heat pipe radiator of multi-layer silk screen structure, changes the structure of existing radiator, to overcome the defective that prior art exists, the solder joint of radiator is reduced, and reduce product cost, and improve radiating efficiency.
The loop heat pipe radiator of the multi-layer silk screen structure that the utility model proposes comprises evaporimeter and condenser, and described condenser is made up of condenser pipe and enhancing heat radiation silk screen; Described enhancing heat radiation silk screen is welded on the condenser pipe, described condenser pipe is spirally, one end of condenser pipe is connected with the steam (vapor) outlet of described evaporimeter, and the other end of condenser pipe is connected with the liquid return tube mouth of described evaporimeter.
The loop heat pipe radiator of the multi-layer silk screen structure that the utility model proposes, its advantage is:
1, in the entire radiator, total pipe interface is reduced to 4 from original 12, greatly reduces and sews possibility, has guaranteed the reliability of heat pipe and the yield rate of product.
2, the radiator that the utility model proposes has been cancelled complicated five-way joint, and the direct and evaporimeter welding of the steam mouth of pipe and condensate liquid refluxing opening has significantly reduced processing and material cost, helps the development of electronic refrigerator.
3, in the radiator of the present utility model, the condenser pipe internal connection is few, and flow regime is improved, and whole heat pipe temperature uniformity improves, the radiating efficiency height.
4, the radiator that the utility model proposes, rational in infrastructure, simple, specious.
Description of drawings
Fig. 1 is the structural representation of the loop heat pipe radiator of the multi-layer silk screen structure that the utility model proposes.
Fig. 2 is an embodiment of the present utility model.
Among Fig. 1 and Fig. 2, the 1st, evaporimeter, the 2nd, condenser, 2-1 are condenser pipes, and 2-2 strengthens the heat radiation silk screen, and 2-3 is a steam (vapor) outlet, and 2-4 is the liquid return tube mouth.
The specific embodiment
The loop heat pipe radiator of the multi-layer silk screen structure that the utility model proposes, its structure comprise evaporimeter 1 and condenser 2 as shown in Figure 1.Condenser 2 is made up of condenser pipe 2-1 and enhancing heat radiation silk screen 2-2.Strengthening heat radiation silk screen 2-2 is welded on the condenser pipe 2-1, condenser pipe 2-1 is spirally, one end of condenser pipe is connected with the steam (vapor) outlet 2-3 of described evaporimeter, and the other end of condenser pipe is connected with the liquid return tube mouth 2-4 of described evaporimeter.
The structure of an embodiment of the present utility model as shown in Figure 2, its preparation process is that whole piece is welded with the condenser that is two-layer band silk screen after the spirally condenser pipe 2-1 doubling of silk screen, make two-layer silk screen have only a steam mouth of pipe and a condensate liquid backflow mouth of pipe, again with two two-layer silk screens and be unified into four layers of silk screen condenser.Whole four layers of silk screen have only two steam mouths of pipe and two condensate liquid backflow mouths of pipe, and they are welded on the evaporimeter 1 at last, and radiator is just as the loop circuit heat pipe system that is made of two plate-like condenser pipes in parallel like this.Also can and be unified into six layers of silk screen condenser, promptly become the loop heat pipe radiator of multi-layer silk screen structure three two-layer silk screens.
The loop heat pipe radiator of the multi-layer silk screen structure that the utility model proposes, its operation principle is: the die cavity of evaporimeter 1 inside of radiator and spirally condenser pipe 2-1 form a sealing system, after inside vacuumizes, be filled with a certain amount of working medium such as ammonia or freon etc., with after its sealing, form a loop circuit heat pipe system again.The thermoelectron assembly occurred frequently (as the electronic cooling sheet) of needs heat radiation is close to the front of evaporation ends, herein, liquid heat absorption evaporation in the evaporimeter die cavity, steam by spirally condenser pipe 2-1 with heat delivery to whole condenser, heat by be welded on the heat pipe silk screen towards periphery air row loose.Become liquid after steam among the spirally condenser pipe 2-1 condenses and get back to evaporation ends by liquid return tube, continue the heat absorption evaporation, so continuous circulation makes the electronic building brick cooling.
The loop heat pipe radiator of the multi-layer silk screen structure that the utility model proposes, condenser is made up of the spirally pipeline of two bilayers, is welded with silk screen on its pipeline.In an embodiment of the present utility model, four layers of condenser pipe and silk screen have only two steam mouths of pipe and two condensate liquid backflow mouths of pipe, therefore compare with existing radiator, cancelled complicated five-way joint, direct and the evaporimeter welding of the steam mouth of pipe and condensate liquid refluxing opening has significantly reduced processing and material cost.
