Abstract

The utility model discloses a coil-type heat exchanger comprising a pipe strap and a plurality of radiating fins which are arranged on the pipe strap; the heat and cold exchanger comprises the whole pipe strap which is bent into a disc shape; the pipe strap and the radiating fins are integrated; and one or more fluid channels are also arranged in the pipe strap. The heat exchanger adopts a technology in which the pipe strap and the fins are integrated, so that the heat transfer performance is better than that of comparable products; because the heat exchanger comprises the whole pipe strap, sectional welding does not need to be carried out, so that the sealing performance and the pressure resistance of the product are better than those of comparable products which are welded with pipelines in a sectional way; and in addition, not much stamping, cutting and welding procedures are needed, so that the manufacturing cost is effectively reduced.

Description

A kind of tube coil type heat exchanger

Technical field

The utility model relates to a kind of heat exchanger, particularly a kind of tube coil type heat exchanger that has radiating fin.

Background technology

Heat exchanger claims heat exchanger and heat transmission equipment again, makes to carry out exchange heat between two kinds of fluids and realize heating or the equipment of purpose such as cooling.For the duct type heat exchanger that has radiating fin, heat transmits between two kinds of fluids by tube wall and radiating fin, the thermal conductivity of tube wall and fin like this, the structure of tube wall, the structure of fin and quantity, and the connection between tube wall and the fin is to the directly influence of height generation of heat conduction efficiency.A kind of as heat exchanger, existing tube coil type heat exchanger is welded into different shapes on demand by metallic conduit usually, and at its surface soldered metal fin to strengthen the heat exchange effect.This type of structure that is welded to connect exists some geneogenous weakness, such as:

Unavoidably there are phenomenons such as rosin joint, sealing-off, leakage weldering during welding, cause pipeline and radiating fin loose contact and reduce heat conductivility;

Between pipeline and the pipeline, need to use solder to connect as media between pipeline and the radiating fin, it is greatly inferior that solder and the metal of making pipeline and radiating fin are compared heat-conductive characteristic, thereby further reduced heat conductivility.

Because between pipeline and the pipeline, be welded to connect by solder between pipeline and the radiating fin, three's thermal coefficient of expansion may be different, because of the generation stress that is heated, cause fin and pipeline to come off easily in heat transfer process, reduced heat conductivility once more.

Summary of the invention

To overcome above-mentioned shortcoming in order solving, to the utility model proposes a kind of novel disc heat interchanger, use whole piece pipe racks and integrated radiating fin to form heat exchanger, greatly improved heat-conductive characteristic.

The technical solution adopted in the utility model can be described as:

A kind of tube coil type heat exchanger, it is made up of the pipe racks that a whole piece bends to plate-like, also contains one or more fluid passages in the described pipe racks.

As a kind of improvement of above technical scheme, described heat exchanger also comprise be arranged on the pipe racks and with the integrated a plurality of radiating fins of pipe racks.

As a kind of improvement of above technical scheme, described radiating fin is arranged on one or two sides of described pipe racks.

As a kind of improvement of above technical scheme, described radiating fin is made up of the fin of a section or multistage, and wherein said multistage radiating fin comprises continuously and discontinuous multistage fin.

As a kind of improvement of above technical scheme, the shape of described radiating fin comprises straight line, triangle, trapezoidal and sinusoidal bent bellows-shaped, and its longitudinal profile is circular-arc.

As a kind of improvement of above technical scheme, the shape that described pipe racks is bent into comprises circle, polygon (more than 4 limits), ellipse, rectangle and U-shaped.

As a kind of improvement of above technical scheme, when described fluid passage was a plurality of, its type comprised singly advancing to have more type, advances more single removing from mould and singly advances single removing from mould.

The beneficial effects of the utility model are:

Pipeline and fin are one-body molded, and heat-conductive characteristic is better than using the like product of welding;

Heat exchanger is made of the whole piece pipeline, does not need the merogenesis welding, and the sealing of product and compression resistance all are better than the like product of pipeline merogenesis welding;

Because this heat exchanger is made by the whole piece pipe bending, the operation of do not need a large amount of punching presses, cut, welding has reduced manufacturing cost effectively.

The specific embodiment

Shown in Fig. 1,3 and 4, a kind of tube coil type heat exchanger, it is made up of the pipe racks 1 that a whole piece bends to plate-like, and pipe racks 1 contains one or more fluid passages 11, and has water inlet 12 and delivery port 13 that is connected with the fluid passage and the mounting bracket 14 that is used for fixing heat exchanger.

Alternatively, as shown in Figure 2, pipe racks 1 is provided with a plurality of integrated radiating fins 2, and described radiating fin 2 can be arranged on the single side of pipe racks 1, also can be arranged on two sides of pipe racks 1 to strengthen the heat exchange effect.

In addition, radiating fin 2 is made up of the fin of a section or multistage, and wherein the multistage radiating fin can be continuous or discontinuous, with reference to the distribution of the radiating fin on Fig. 3 and 42.The shape of described radiating fin 2 comprises straight line, triangle, trapezoidal and sinusoidal bent bellows-shaped, and with reference to Fig. 5-8, its longitudinal profile is circular-arc, with reference to Fig. 9.

Shown in Figure 10-14, pipe racks 1 can be bent into multiple shape to be fit to different working environments, as circle, polygon (more than 4 limits), ellipse, rectangle and U-shaped by demand.
