Abstract

Disclosed is a heat pipe web radiator which comprises a metal heat exchanging block (1) and a heat pipe web which is composed of a plurality of spiral bent evaporation tubes (2) and radiation wires (3), wherein both ends of the evaporation tubes (2) are connected with the enclosed heat exchanging chamber (11) of the heat exchanging block (1) respectively. The utility model is characterized in that the entine of the heat exchanging chamber (11) of the heat exchanging block (1) is provided with channels (12). In order to facilitate the processing, the heat exchanging chamber (11) can be two parallel cylindrical holes which are communicated in the middle, and the channels (12) are distributed axially, parallel and homogeneously on the entines of the cylindrical holes. In order to intensify the evaporating and radiation effect, the crosswise sections of the evaporation tubes (2) are all positioned obliquely to promote the refrigerating liquid in tubes to reflux more rapidly. Compared with the prior art, because of the additional arrangement of the channels on the entine of the heat exchanging chamber of the heat exchanging block, the heat exchanging area of the utility model increase many times, thereby improving heat exchanging effect greatly. Meanwhile, the oblique arrangement of the crosswise sections of the evaporation tubes promotes the refrigerating liquid in tubes to reflux more rapidly and helps improve the entire radiation effect further.

Description

Heat pipe silk screen radiator

Technical field

The utility model relates to a kind of radiator of refrigerating plant, particularly a kind of heat pipe silk screen radiator that is used for semiconductor cooling device.

Background technology

Existing water dispenser with refrigerating function adopts the semiconductor refrigerating mode mostly, its radiator is a heat pipe silk screen type, promptly include the heat transfer block of a metal material (generally adopting aluminium alloy) and by the multistage heat pipe silk screen that crooked evaporation tube and heat radiation silk constitute that unrolls, the two ends of evaporation tube are connected with the closed heat exchanging chamber of heat transfer block respectively.Yet in the existing heat pipe silk screen radiator, the heat exchanging chamber inwall of its heat transfer block is smooth, so the heat exchange effect is good inadequately, and in addition, each traversing section is and is horizontally disposed with in the evaporation tube, does not utilize the Channel Group of refrigerating fluid, also influences the heat exchange effect.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of through heat pipe silk screen radiator improved, the heat exchange better effects if at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this heat pipe silk screen radiator includes the heat transfer block of a metal material and by the multistage heat pipe silk screen that crooked evaporation tube and heat radiation silk constitute that unrolls, the two ends of evaporation tube are connected with the closed heat exchanging chamber of heat transfer block respectively, it is characterized in that the heat exchanging chamber inwall of described heat transfer block has the groove of being provided with.

For strengthening the heat exchange effect, described number of grooves should be many as much as possible, are good to be covered with the heat exchanging chamber inwall; Be convenient processing, described heat exchanging chamber can be two cylindrical holes that are parallel to each other and are communicated with at the middle part, and described groove is distributed on the described cylindrical hole inwall to good with axially parallel.

For strengthening the evaporative heat loss effect, each traversing section of described evaporation tube is for being obliquely installed, so that the refrigerating fluid in the pipe refluxes quickly.

Compared with prior art, the utility model is set up groove by the heat exchanging chamber inwall at heat transfer block, increased heat exchange area exponentially, thereby the heat exchange effect is significantly improved, simultaneously, being obliquely installed of each traversing section of evaporation tube refluxed the refrigerating fluid in the pipe soon, and the integral heat sink effect is further improved.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, heat pipe silk screen radiator includes the heat transfer block 1 of a metal material and by multistage unroll a crooked evaporation tube 2 and heat radiation silk 3 heat pipe silk screens that constitute;

Shown in Fig. 3～5, have two cylindrical holes 11 that are parallel to each other and are communicated with through passage 13 in the heat transfer block 1 as heat exchanging chamber at the middle part, the parallel vertically groove 12 that is evenly equipped with of its inwall, the two ends of evaporation tube 2 promptly are connected with two cylindrical hole heat exchanging chambers 11 of heat transfer block 1 respectively;

Each traversing section of described evaporation tube 2 is for being obliquely installed, so that the refrigerating fluid in the pipe refluxes quickly.

Design of the present utility model comes from the semiconductor refrigerating water dispenser, but according to structure of the present utility model, can be used for equally in other refrigerating plants.
