Abstract

The invention discloses an inner spiral efficient space-saving type heat exchange pipe, which relates to the technical field of heat exchange, mainly consisting of a heat exchange main pipe 11 and an inner spiral sheet 12. In essence, the inner spiral efficient space-saving type heat exchange pipe is characterized in that on the basis of the coil pipe type (or similar) heat exchange pipe, an outer surface 21 of a coil pipe is fused into the current uncoiled pipe type heat exchange main pipe 11, and the inner surface 22 can be degenerated into the inner spiral sheet 12, so the novel heat exchange pipe with higher heat exchange efficiency can be manufactured by a simple process at low cost. In addition, the heat exchange pipe does not take the minimum bending radius of a single pipe into account, and the outer diameter of the heat exchange main pipe 11 is the outer diameter of the heat exchange device.

Description

A kind of efficient save space type heat exchanger tube of inside spin

Technical field

The present invention relates to the efficient save space type heat exchanger tube of a kind of inside spin in heat transfer technology field.

Background technology

Present heat exchanger all is mature on the whole in performance and configuration aspects, but the designer does not consider its miniaturization in most cases, and causing can't desirable heat exchanger or the heat exchanger tube of installation capability in the less place of some headspace.And, behind the heat exchanger tube internal incrustation, almost can't remove clean or remove very difficult.

Summary of the invention

The present invention is intended to solve above-mentioned problem, proposes the high novel heat exchange pipe of saving the space of a kind of performance.It mainly is made up of the heat exchange person in charge, inner screwy fin two parts.The diameter that heat exchange is responsible for is bigger slightly than common heat exchanger tube diameter, interior dress inner screwy fin, and ` fixes with the form of interference fit but can weld also.

The technology of most critical of the present invention is that the inner screwy fin that embedded one section its external diameter equals its internal diameter is responsible in heat exchange.This structure in essence, be on the basis of coiled (or similarly) heat exchanger tube, the heat exchange that the coil pipe outer surface is fused into present non-helical type is responsible for, and inner surface degenerates into inner screwy fin, but ` produces the higher novel heat exchange pipe of heat exchange efficiency with lower cost and simple technology.In addition, for increasing the heat exchange area that heat exchange is responsible for, can outside it, install heat exchange fin additional or shut out screw thread or employing alternate manner increase heat exchange efficiency.

The advantage of comparing this novel heat exchange pipe with existing heat exchanger is:

1. the parts of most critical of the present invention are to be embedded in heat exchange to be responsible for interior inner screwy fin, and it both can prevent the cold and hot mixing of heat absorption material in the heat exchange person in charge, can reach the heat exchange effect of coil exchanger again;

2. volume is little, because inner screwy fin has been arranged, this form no longer is responsible for for improving heat exchange efficiency bending heat exchange, and the external diameter that heat exchange is responsible for is exactly the heat exchanger external diameter, makes full use of the heat exchanger space;

3. the simple materials of technology are economized, and only moulding material are assembled and need not carry out any additional heat treatment, and material is economized more than 30%, and these materials overwhelming majority is non-ferrous metals such as copper, aluminium.

4. easy to clean, inner screwy fin and heat exchange can be responsible for fractionation, carry out dirt removal completely.

5. efficient height installs the novel heat exchange pipe of heat exchange fin additional, and efficient is suitable with other efficient heat-exchanging pipe.

The specific embodiment

Following several embodiment is in conjunction with the accompanying drawings to further explanation of the present invention and explanation, and the present invention is not constituted any limitation.Specific embodiment one:

The inside spin type efficient heat-exchanging pipe that the present invention proposes mainly is made up of the heat exchange person in charge 11, inner screwy fin 12 two parts, interior dress inner screwy fin, and welding is fixing.The external diameter of inner screwy fin 12 is responsible for 11 internal diameters with heat exchange and is equated, the route that assurance material wherein limits by inner screwy fin 12 moves and do not flow through between the flight 12 and the heat exchange person in charge 11.

Specific embodiment two:

On the basis of specific embodiment one, do following improvement: A, inner screwy fin 12 and the heat exchange person in charge 11 and adopt the form of interference fit to fix, compare welding and can improve the reliability that does not occur the gap in the pipe.

Claims

1. the efficient save space type heat exchanger tube of an inside spin is made up of the heat exchange person in charge (11) and inner screwy fin (12), it is characterized in that:

The inner screwy fin (12) that external diameter equals the heat exchange person in charge (11) internal diameter is fixed in the heat exchange person in charge (11) by welding and interference assembling mode.
