Abstract

The utility model reveals a spoke cavity type heat exchanger which not only is simple in structure and low in cost, but also has higher heat exchange efficiency. The characters thereof are that: a cylinder spoke cavity core whose two ends are separately connected with inner cavity outlet elbow and inner cavity inlet guide cylinder by left and right small cylinders is arranged in metal cylinders; the spoke cavity core is folded into wave-shaped by a thin metal plate and both sides of all wave troughs are sealed by melding then rolled to cylinders to meld into two mediums in different temperatures which flow reversely along axial direction in the inner, outer cavity formed by this structure under the same insignificancy pressure and produce heat exchange. Adopting spoke cavity structure is big in heat exchange area and the effect is obvious together with net reverse heat exchange. The utility model has very high utilization value.

Description

Raia formula heat exchanger

Technical field

The utility model relates to a kind of heat-exchanger rig.

Background technology

At present, known heat exchanger has shell and tube, puts down and pull formula, rolled plate etc., and they all can reach bearing requirements, but the manufacturing process complexity, cost is higher, is difficult for scale removal.

Summary of the invention

In order to overcome the deficiency of existing heat exchanger complex process, the utility model provides a kind of raia formula heat exchanger, and it is not only simple in structure, cost is low but also the heat exchange efficiency height.

The technical scheme that its technical problem that solves the utility model adopts is: the Cylinder raia core that little garden tube links to each other with inner chamber outlet bend pipe and inner chamber inlet guide respectively about two ends are set in the tube of metal garden pass through, this raia core is folded into waveform by a metal sheet, and, be rolled into Cylinder then and be welded the both sides welded seal of all troughs.The different medium of two temperature produces the heating power exchange reciprocal vertically flowing in the inside and outside chamber that this structure forms respectively under the identical humble pressure.

The beneficial effects of the utility model are, owing to adopt metal sheet, make simplicity of design and compact structure can be easy to processing and material-saving.Not only cost is low, and the heat exchange area of raia structure is big, and pure in addition reverse heat-exchange effect is remarkable, is better than the heat exchanger of other structure.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a profilograph of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

By the heat exchanger that architectural feature in the scheme makes, inside and outside raia is the autonomous channel separately, is sealing state between the two.Heat exchanger right-hand member medium flows into through inner chamber inlet guide 1 and right roundlet tube 2 under humble pressure, through minute fluidization tower 3 distributes equably enter in the raia 4, flow vertically, after left roundlet tube 5 and inner chamber export bend pipe 6 outflows.And at left end, medium also enters in the metallic cylinder 9 under identical humble pressure, and enters in all outer raias 7, becomes reverse flow with the medium that right-hand member enters in the interior raia 4 vertically, carries out the heating power exchange., finish heat transfer process after exocoel outlet cylinder 8 is discharged.

Claims

1, a kind of raia formula heat exchanger, it is characterized in that little garden tube (5) (2) about two ends are set in metal garden tube (9) to be passed through respectively with inner chamber outlet bend pipe (6) and the inner chamber Cylinder raia core that guide (1) links to each other that enters the mouth, this raia core is folded into waveform by a metal sheet, and, be rolled into Cylinder then and be welded the both sides welded seal of all troughs; The different medium of two temperature produces the heating power exchange reciprocal vertically flowing in the inside and outside chamber that this structure forms respectively under the identical humble pressure.
