Abstract

The utility model discloses a coil pipe heat exchanger. The coil pipe heat exchanger comprises a housing and a coil pipe arranged in the housing, wherein the coil pipe is formed by at least two pipe columns in a sleeved manner; and each pipe column is formed by randomly coiling pipes in a gradually spiral manner. According to the utility model, the coil pipe is formed by the at least two pipe columns in a sleeved manner to form a multi-layer coil pipe; the wall surfaces of the multi-layer coil pipe are used as heat exchange surfaces, so that heat exchange area in the housing of the heat exchanger is large, the flow of tube side fluid of the heat exchanger is big within a unit time, and the heat exchange efficiency is high.

Description

Coil heat exchanger
Technical field
The utility model relates to a kind of heat exchanger, is specifically related to a kind of coil heat exchanger.
Background technology
Heat exchanger claims again heat exchanger, is the equipment that carries out heat exchange between cold fluid and hot fluid, and in departments such as chemical industry, oil, power, food, heat exchanger is widely used as heater, cooler and condenser.Different according to the heat exchange mode between cold fluid and hot fluid, heat exchanger can be divided three classes: 1. 2. 3. heat regenerator of contact heat exchanger of dividing wall type heat exchanger.Wherein, dividing wall type heat exchanger is pressed the version of heat-transfer area, is divided into again pipe heat exchanger (such as shell-and-tube heat exchanger, coil heat exchanger, double-tube heat exchanger, spray-type heat exchanger, aerial cooler etc.) and plate type heat exchanger (such as spiral heat exchanger, plate-type exchanger, plate-fin heat exchanger etc.).
The aforementioned tube shell heat exchanger claims again tubular heat exchanger, is to be enclosed in the wall of restraining in the housing as the dividing wall type heat exchanger of heat-transfer area, and the cold and hot two kinds of fluids that carry out heat exchange, a kind of mobile in pipe, be called tube side fluid; Another kind of mobile outside pipe, be called shell-side fluid.Shell-and-tube heat exchanger requires to select according to actual heat exchange take U-shaped heat exchange of heat pipe and coil heat exchanger as main.
The coil pipe of coil heat exchanger is coiled to form arbitrarily by the tubing spiral of pipe, elliptical tube, quadrangle pipe, flat tube or other cross sectional shape is progressive.Early stage coil heat exchanger mostly is greatly the single coil heat exchanger, relies on the wall heat exchange of single coil, and heat exchange area is little, and the flow of heat exchanger tube pass fluid is little in the unit interval, and heat exchanger effectiveness is low.
Chinese invention patent CN101738121B discloses a kind of coil pipe and has had the heat exchanger of this coil pipe, described coil pipe is comprised of with the arcuation pipe that tail end is connected into the continuous bend line successively mutually several head ends, when the angle of crossing between the head end of described arcuation pipe and the tail end was 360, coil pipe was for to be coiled to form arbitrarily by the tubing spiral is progressive.A wherein embodiment of the present invention is: some vertical coil pipes in the horizontal direction multiple row are arranged and are formed multiple row orthogonal array coil pipe, and every row vertical coil pipe two ends and some separatory hole and some gas collection holes connect one to one in the multiple row orthogonal array coil pipe.Multiple row orthogonal array coil pipe has increased the heat exchange area of heat exchanger, and the flow of heat exchanger tube pass fluid becomes large in the unit interval, and heat exchanger effectiveness is better.But this heat exchanger coils volume is larger, need larger installing space, thereby the heat exchanger shell volume is also corresponding larger, is unfavorable for transportation and the installation of coil pipe and heat exchanger.
Summary of the invention
The utility model purpose provides a kind of coil heat exchanger, and by the improvement of structure, coil arrangement is compact, and the heat exchanger shell volume is little, is beneficial to transportation and the installation of coil pipe and heat exchanger.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coil heat exchanger, and comprise housing and be located at the interior coil pipe of housing, described coil pipe is by at least 2 sheathed forming of tube bank, and each described tube bank is coiled to form arbitrarily by the tubing spiral is progressive.
In the technique scheme, sheathed described tube bank is in parallel, and the head end of outer tube bank is communicated with by adapter respectively with the tail end of internal layer tube bank with the tail end of the head end of internal layer tube bank, outer tube bank.
Described coil pipe can also be following structure, two adjacent described tube bank series connection, and the tail end of outer tube bank is communicated with the tail end of internal layer tube bank.
Further technical scheme, two sheathed described tube banks are coiled to form arbitrarily by tubing spiral is progressive.
In the technique scheme, described tube bank is coiled to form arbitrarily by the tubing spiral of pipe, elliptical tube, quadrangle pipe, flat tube or other cross sectional shape of titanium material is progressive.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. coil pipe of the present utility model consists of the multiple field coil pipe by at least 2 sheathed forming of tube bank, and the wall of all coil pipes is all as heat-transfer surface, and the heat exchange area in the heat exchanger shell is large, and the flow of heat exchanger tube pass fluid is large in the unit interval, and heat exchanger effectiveness is high.
2. coil pipe of the present utility model is by at least 2 sheathed forming of tube bank, and two adjacent tube pitches are little, and coil arrangement is compact, and the heat exchanger shell volume is little, is beneficial to transportation and the installation of coil pipe and heat exchanger.
