Abstract

The utility model relates to a finned coil pipe condenser of an air water heater, which takes a shaped of a cylinder body and comprises a shell (7), a heat-insulating material layer (8), a liner (10) and a coil pipe (4) in a liner cavity and a bracket (6) of a fixed coil pipe, which are arranged from outside to inside, and a freezing medium inlet (2) and freezing medium outlet (5) and a water inlet (1) and a water outlet (9) are arranged on the cylinder body; the finned coil pipe condenser is characterized in that: a fin (3) which is integrated with the pipe body is arranged along the direction of the diameter extension line of the body of the coil pipe (4), at least two fins has the equal length, equal width and equal spacing distance and are distributed in a radial way, so as to solve the problem of gravity balance of the pipe body in water and be beneficial to shock resistance and vibration damping of the coil pipe soaked in the water; and the added fins greatly improve the heat-transmitting efficiency. Under the condition of same heat-transmitting efficiency, the length of the coil pipe can be shortened for reducing the extended-range pressure loss, and the finned coil pipe condenser has the advantages of saving energy and alleviating the work load of compressors.

Description

The band finned coil condenser of air-source water heater

Technical field

The utility model relates to the parts of the hot water supply system in a kind of dwelling house and other place, is the condenser of air-source water heater.

Background technology

The critical piece of air-source water heater has condenser, compressor, evaporimeter and expansion valve, and its condenser is being undertaken the important task of exchange heat, and spiral coil pipe directly contacts with water body in the dependence internal bladder cavity, carries out the transmission of heat.At present, the coil pipe in the condenser of air-source water heater mostly is copper pipe, only contacts with water body by the curved circular tube-surface, and under the situation that does not increase diameter and length, heat transfer surface area is less.If the increase coil lengths is then prolonged stroke pressure and is decreased and to subtract seriously, increased energy consumption of compressor and live load, influence compressor service life.Besides the vibration during compressor operating involves coil pipe, and the coil pipe of tubular is immersed in the water body, and the pipe surface is streamlining almost, is subjected to the resistance of water, cushion effect little, the vibration damping deficiency, and the joint easily gets loose, falls and ruptures.

The utility model content

At the above-mentioned deficiency of prior art, the diameter that the purpose of this utility model provides a kind of coil pipe is constant, length can suitably shorten, do not influence heat transference efficiency and prolong the band finned coil condenser that stroke pressure decreases the air-source water heater that reduces.

Above-mentioned purpose realizes by following measure: the band finned coil condenser of this air-source water heater, be cylinder body, by outer and in be followed successively by the coil pipe and the fixing support of coil pipe in shell, adiabator layer, inner bag and the internal bladder cavity, also have cold-producing medium to import and export and water entrance on the staving, the fin with the body unification is arranged on the coil pipe pipe diameter extended line direction.

At least 2 of fins on the coil pipe body circumference, the width and the length of each bar equate that all the spacing distance between the adjacent fins equates that many fins are radial arrangement on the external wall of pipe.

The beneficial effects of the utility model are increasing of fin, concerning the coil pipe of same diameter, improved the heat transference efficiency of unit length coil pipe, also can suitably shorten coil lengths and prolong the journey loss with what reduce the pipe internal pressure, the favourable energy-conservation and prolongation compressor life-span, the interpolation of fin has improved the Vibrant buffer power of coil pipe in water body, good damping result, and coil pipe is difficult for shattering.

Description of drawings

Fig. 1 is the condenser structure schematic diagram with the coil pipe of two fins.

Fig. 2 is the coil pipe cross-sectional structure schematic diagram (amplification) with many fins.

The specific embodiment

The utility model is described in detail below in conjunction with embodiment and with reference to accompanying drawing: this condenser is cylinder body, in reaching outward is shell 7 successively, adiabator layer 8, inner bag 10, the support 6 that coil pipe 4 and circle price fixing pipe 4 are arranged in the internal bladder cavity, also has water inlet 1, delivery port 9, system cryogen mouth 2, go out cold-producing medium mouth 5, these arrangement modes and structure are identical with the condenser of now general air-source water heater, the utility model only changes the coil pipe of band fin 3 into to the coil pipe 4 of original tubular body, and 3 at least two of fins, the length of each sheet fin, width and spacing distance equate that all many fins 3 are radial arrangement on the external wall of pipe.

Each fin 3 palpus equal in length, width equate, spacing distance equates.This some requirement is be to solve the gravitational equilibrium problem of body in water, help the antivibration and the vibration damping of long-term coil pipe 4 under water, and the interpolation of fin has improved the heat transference efficiency of the coil pipe 4 of equal diameter, equal length greatly.Anti-speech, under the heat transference efficiency situation that equates, can shorten the length of coil pipe, it is favourable that this just prolongs the stroke pressure loss to minimizing, have energy-conservation with alleviate the benefit that compressor operating is loaded.

Claims

1, a kind of band finned coil condenser of air-source water heater, be cylinder body, by outer and in be followed successively by coil pipe (4) and the fixing support of coil pipe (6) in shell (7), adiabator layer (8), inner bag (10) and the internal bladder cavity, also have cold-producing medium to import and export (2,5) and water entrance (1,9) on the staving, it is characterized in that the fin of unifying with body (3) is arranged on coil pipe (4) the pipe diameter extended line direction.

2, the band finned coil condenser of air-source water heater as claimed in claim 1, it is characterized in that (3) at least 2 of fins on coil pipe (4) the body circumference, the width and the length of each bar all equate, spacing distance between the adjacent fins equates that many fins (3) are radial arrangement on the external wall of pipe.
