Abstract

The utility model relates to a heat exchanger which is mainly composed of a housing, an inner sleeve, spiral coil pipes, a base, etc., wherein the housing is a pipe body, the top surface thereof is sealed, and the bottom surface thereof is provided with a flange; the housing is sheathed outside the inner sleeve; the inner sleeve is also a pipe body, the lower end of which is fixed on the base and one layer or multiple layers of spiral coil pipes are wound outside the pipe body. Both ends (namely outlets/inlets) of the spiral coil pipes all penetrate through the base and are exposed outside the base. With the adoption of the structure, the assembly and the disassembly of the housing and the spiral coil pipes are convenient, and problems that a traditional heat exchanger is not easy to clean and maintain, etc. can be solved.

Description

Heat exchanger

Technical field

The utility model relates to heat exchanger, the helical disk tubular type heat exchanger that especially a kind of disassembly, cleaning are convenient, rate of heat exchange is high.This heat exchanger can be widely used in fields such as air-conditioning.

Background technology

The heat-exchange tube of common heat exchangers mostly adopts shell-tube type and sleeve pipe spiral fashion so (being commonly called as " She Pao "), and wherein shell-tube type belongs to the two plate heat exchange, and cooling water requires high, and after long-time the use, the incrustation scale of formation is not easy to clean.Particularly cool off when bad when heat exchange tube, whole housing internal pressure can raise rapidly, just in case protect the potential safety hazard such as heavy explosion that promptly may cause out of control.Use more sleeve pipe spiral fashion so (She Pao) in recent years, heat exchange efficiency is than straight pipe type heat exchanger height, but heat-exchange tube is difficult to clean at the long-time incrustation scale that uses the back to form.If any heat exchanger just have of this sort problem, its structure is for directly welding upper and lower cover at the upper and lower of housing respectively, form a complete seal, like this, heat exchanger is in the long-time just easy cleaning not of incrustation scale that the back forms of using, as adopt liquid medicine to clean, be unfavorable for environmental protection again, run into the heat-exchange tube that breaks and just can not keep in repair, and set up screw type space bar, make complex process, cost increases.

Summary of the invention

The purpose of this utility model provides a kind of heat exchanger, so that overcome problems of the prior art.

The realization the technical solution of the utility model is: this heat exchanger comprises shell, interior cover, coil pipe, base, its primary structure is the outside of cover in described shell is enclosed within, this shell and interior cover all are installed on the base, be provided with spiral coil between shell and interior cover, the outlet of this spiral coil and inlet all pass base and are arranged on outside the base; The upper and lower appropriate location of described shell periphery is respectively equipped with the cooling medium entry and exit of communication with cavity.

This technical scheme also comprises:

The outside of cover in described spiral coil is enclosed within is distributed with some and the corresponding keeper of spiral coil at the circumferential surface of interior cover, and spiral coil is fixed on the keeper.

Described spiral coil is one or more layers.

Described shell lower end is provided with and base flange connecting dish.And

Be provided with sealing ring between described ring flange and the base.

The beneficial effects of the utility model are that 1 adopts electrodeless formula heat exchange method, heat exchange efficiency height; The shell of 2 heat exchangers can conveniently be taken apart, need not to use liquid medicine just capable of washing clean, helps environmental protection, increases the service life; 3 have adopted the single or multiple lift heat-exchange tube, can improve heat exchange power, and easy for installation, make the high pressure medium that is present in than in the small coils not have any potential danger; 4 manufacture crafts are simple, and cost is lower, long service life.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in the figure, the utility model mainly is made up of shell 1, interior cover 2, spiral coil 12, base 11 etc., and wherein shell 1 is a body, its end face sealing, and there is a ring flange 10 its bottom surface; The outside of cover 2 in shell 1 is sleeved on, interior cover 2 also is a body, its lower end is fixed on the base 11 (square plate or circular slab), its outside is surrounded with one or more layers spiral coil 12 (can set the number of plies of spiral coil as required), the two ends of this spiral coil 12 (both gateways) all penetrate base 11, be exposed at the outside of base, this structure can make things convenient for the dismounting (having solved the problem that should not clean and safeguard) of shell and spiral coil; For vibration or the activity that prevents spiral coil, must be fixed, circumferential surface at interior cover 2 is fixed with some keepers 4 (can decide as required) along the hand of spiral (should be corresponding with the spacing of spiral coil) for this reason, spiral coil just is fixed together with keeper, when fixing multi-layer helical coil pipe, keeper 4 can suitably extend; The ring flange 10 of shell 1 lower end is fixed on the base 11 by bolt 6, for preventing to leak, between the ring flange of base and shell lower end sealing ring 7 is set.This heat exchanger is equipped with the medium that is cooled in its spiral coil, and this medium that is cooled can flow as outlet or inlet from pipe end 3,5 arbitrary ends of spiral coil, the outlet by cooling medium is arranged and enter the mouth 8,9 at the circumferential surface of shell 1 in addition.Above cooling medium is comparatively speaking with the medium that is cooled, just their flow direction must be opposite, must be high-pressure medium or cleaner medium in spiral coil, what flow between shell and interior cover must be low-pressure medium or impure more medium.
