Abstract

The utility model discloses a coaxial spiral tubes heat exchanger, which is formed through the nesting of an inner pipe and an outer pipe, wherein guiding pipes are arranged at the two ends of the inner pipe and the outer pipe. The heat exchanger also comprises a core pipe arranged on the axis of the outer pipe, the two ends of the core pipe are connected in parallel with an inner ring of the outer pipe, and the inner pipe is spirally distributed in the outer pipe. The core pipe is arranged in the inner pipe of the spiral sleeve, refrigerating fluid is filled in both the outer pipe and the core pipe and water is filled between the inner pipe and the core pipe; therefore, heat exchange is performed at the two sides of a water path of the inner pipe and the heat exchange efficiency of the heat exchanger is improved.

Description

Coaxial screw shell heat-exhanger
Technical field
The utility model relates to a kind of coaxial screw shell heat-exhanger, belongs to the Refrigeration Technique devices field.
Background technology
Heat exchanger is as the parts of extensive use in the Refrigeration Technique, and the height of its heat exchanger effectiveness directly influences the efficient of whole refrigeration system.At present, most of double pipe heat exchangers all are to adopt the form of coaxial pair of sleeve pipe to constitute, such heat exchanger can satisfy certain Technology Need, the water at casing axis place but there is also shortcoming: owing to can not carry out heat exchange well with the cold-producing medium in the outer tube, make the heat exchange effect of heat exchanger bad, thereby influenced the efficient of whole refrigeration system.
The utility model content
The utility model provides a kind of coaxial screw shell heat-exhanger for the deficiencies in the prior art.
The utility model can be achieved by taking following technical scheme:
A kind of coaxial screw shell heat-exhanger is made of interior pipe, outer tube fit, and the two ends of described interior pipe, outer tube are connected to guide wire, also comprise the core pipe, described core pipe places on the axis of outer tube, and the two ends of core pipe are in parallel with the interior ring of outer tube, the shape distribution in the shape of a spiral in outer tube of described interior pipe.
Compared with prior art, the utlity model has following advantage: the utility model is by the interior pipe core pipe at screw shell, in outer tube and in the core pipe, all feed the refrigeration Ji, feed water between interior pipe and the core pipe, all carry out heat exchange in the both sides in interior pipe water route like this, the heat exchange efficiency of heat exchanger is improved.
Description of drawings
Fig. 1 is the overall structure figure of coaxial screw shell heat-exhanger of the present utility model.
Fig. 2 is the partial structurtes cut-away view of coaxial screw shell heat-exhanger of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, coaxial screw shell heat-exhanger of the present utility model, constitute by interior pipe 1, outer tube 2 fits, the two ends of pipe 1, outer tube 2 are connected to guide wire in described, also comprise core pipe 3, described core pipe 3 places on the axis of outer tube 1, and the two ends of core pipe 3 are in parallel with the interior ring of outer tube 2, the shape distribution in the shape of a spiral in outer tube 2 of described interior pipe 1.When cold-producing medium enters tube connector 4 after interior ring enters in outer tube and the core pipe simultaneously, then feed water between interior pipe that spiral distributes and the core pipe, like this, all carry out heat exchange, make that the heat exchange efficiency of heat exchanger is improved greatly with cold-producing medium in the both sides of water circulation pipe.

Claims (2)
