Abstract

A tube-tube interlaced type heat exchanger comprises two metal tubes, thermal-insulating tube sleeves and a metal tube sleeve sealed connecting component. The two metal tubes are tightly interlaced spirally. The tube-tube interlaced type heat exchanger can extend in any direction at will, the length of the tube-tube interlaced type heat exchanger can be changed at will, and the blank of an application field of the heat exchangers is filled up; the chosen types of the heat exchangers are increased; and furthermore, the tube-tube interlaced type heat exchanger is low in manufacturing process requirement and cost, compact in structure and convenient to use.

Description

Pipe pipe is entwined formula heat exchanger

Technical field:

The invention provides a kind of heat exchanger, especially relate to a kind of pipe pipe and to entwine formula heat exchanger.

Technical background:

Present heat exchanger kind is a lot, but heat exchanger effectiveness is high, and the heat exchanger that arbitrarily can convert again direction of extension and length is little, does not even have, bothers very much.The present invention be exactly in order to realize heat exchanger effectiveness height can arbitrarily convert again direction of extension and length object and a kind of pipe pipe of designing is entwined formula heat exchanger.

Summary of the invention:

A kind of pipe pipe is entwined formula heat exchanger, comprises metal tube, heat-insulating cover, the airtight attaching parts of metal pipe sleeve, wherein:

Described metal tube needs two;

Described two strip metal pipes will closely be entwined together as helical form.

Concrete embodiment:

A kind of pipe pipe is entwined formula heat exchanger, comprises metal tube, heat-insulating cover, the airtight attaching parts of metal pipe sleeve, wherein:

Described metal tube is preferably flat-shaped, also can be other shape;

Described metal tube preferably copper pipe also can be other metal tube;

Described metal tube needs two;

Described two strip metal pipes will closely be entwined together as helical form;

Described heat-insulating cover is used for closely being enclosed within outside the two strip metal pipes of entwining together, to protect metal tube and to avoid the heat loss that exchanges;

The airtight attaching parts of described metal pipe sleeve be used for connection two sections shaping after pipe pipe to entwine formula heat exchanger.

This pipe pipe formula heat exchanger of entwining can arbitrarily convert direction of extension and length, fill up the blank of an application of heat exchanger, add the type selecting of heat exchanger, and manufacture process requirement and cost are not high, compact conformation, easy to use, once promoting the use of, to promoting that the development of the industrial civilization of entire society has important practical significance.
