Abstract

The utility model relates to a self-oscillating flow heat pipe with a liquid storage tank, comprising a pipeline in which a working medium is packaged, wherein the pipeline is communicated with the liquid storage tank, and the working medium is stored in the liquid storage tank. In the self-oscillating flow heat pipe, the working medium capacity is increased through the liquid storage tank, and the heat transfer efficiency of the self-oscillating flow heat pipe is improved.

Description

The selfexcited oscillating-flow heat pipe of band fluid reservoir

Technical field

The utility model relates to hot pipe technique, particularly selfexcited oscillating-flow heat pipe.

Background technology

Selfexcited oscillating-flow heat pipe all has a pipeline of bending repeatedly.Operation principle according to selfexcited oscillating-flow heat pipe; The internal diameter of the pipeline of selfexcited oscillating-flow heat pipe must be done very for a short time, and usually less than 1mm, so the capacity of pipeline is very limited; The working medium that can encapsulate in the pipeline is less, has restricted the heat transfer efficiency of selfexcited oscillating-flow heat pipe thus.

The utility model content

The purpose of the utility model provides a kind of selfexcited oscillating-flow heat pipe with fluid reservoir, to improve the heat transfer efficiency of selfexcited oscillating-flow heat pipe.

The utility model is achieved in that a kind of selfexcited oscillating-flow heat pipe with fluid reservoir, comprises the pipeline that is packaged with working medium, and said pipeline is communicated with fluid reservoir, stores said working medium in the fluid reservoir.

The utility model has the advantages that: increased the working medium capacity through fluid reservoir, thereby improved the heat transfer efficiency of selfexcited oscillating-flow heat pipe.

The specific embodiment

Referring to Fig. 1, selfexcited oscillating-flow heat pipe comprises pipeline 1, is packaged with working medium in the pipeline 1.Described working medium can be water, acetone, ethanol, R142b, R123 etc.The characteristics of the utility model are that pipeline 1 is communicated with fluid reservoir 2, store said working medium in the fluid reservoir 2.According to actual needs, pipeline can be communicated with a plurality of fluid reservoirs, and is for example shown in Figure 2, and the pipeline 1 of whole selfexcited oscillating-flow heat pipe is communicated with three

fluid reservoirs

2,3,4, and each fluid reservoir all stores said working medium.The trend of pipeline 1 is decided according to the actual requirements, and not limited by accompanying drawing.

The cross section of pipeline 1 is preferably rectangle, and the heater that so can be convenient to directly will dispel the heat directly is fixed on the pipeline outer wall.For example, when this selfexcited oscillating-flow heat pipe is applied in the LED light fixture, can led chip directly be fixed on the outer wall of pipeline 1.

Pipeline and the fluid reservoir that is communicated with thereof are preferably made an integral body.Fig. 3 and combine Fig. 4, shown in Figure 5 for example; Pipeline 1 and three

fluid reservoirs

2,3,4 that are communicated with thereof all are to be put together by double layer of

metal plate

5,6; Double layer of

metal plate

5,6 forms the type groove respectively, and the type groove of double layer of

metal plate

5,6 constitutes pipeline 1 and

fluid reservoir

2,3,4 in the amalgamation face amalgamation of double layer of metal plate.The embodiment that another kind is equal to; Also can and combine Fig. 6, shown in Figure 7 like Fig. 3; Have only layer of metal plate 5 to be provided with the type groove, another layer metallic plate 6 do not have the type groove, and the type groove on the metallic plate 5 constitutes pipeline 1 and

fluid reservoir

2,3,4 at the amalgamation face of double layer of

metal plate

5,6.

The metallic plate that constitutes pipeline and fluid reservoir is preferably stainless sheet steel, and has flexible pliability.Be more convenient for the installation of light fixture like this.

For strengthening radiating effect, can set up radiating fin at the outer wall of pipeline and/or fluid reservoir.
