Abstract

The utility model relates to a coiled pipe-embedded condenser with fins, comprising a water inlet (1), a water outlet (5), an outer housing (6), a heat insulating material layer (7), a barrel-shaped liner (9) and a coiled pipe (4), wherein a spiral pipe-embedding groove (2) is installed on the outer wall of the liner (9); fins (3) are arranged outside the coiled pipe (4); the pipe is embedded in the pipe-embedding groove (2); the fins (3) are attached on the outer wall of the liner; and a heat reflecting layer (8) is covered on the liner together with the embedded coiled pipe and fins. The condenser is slightly influenced by vibration, does not have scale, is not eroded by water, and bears uniform pressure; by embedding or burying the coiled pipe, the heat transmission efficiency is improved and the positioning is firm; the pipe-embedding groove 2 has the effect of strengthening ribs for the liner wall, thereby facilitating to prolong the service life of the condenser; and the fins and heat reflecting layer of aluminum foil composite film are added, so the heat transmission efficiency is further improved.

Description

The embedded condenser of band finned coil

Technical field

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

Background technology

Air-source water heater includes condenser, compressor, evaporimeter and four kinds of critical pieces of expansion valve, and condenser is being born the important task of heat exchange.Generally electric heater, fuel-oil water heater, gas heater, the solar water appliance of usefulness have that energy consumption is little to air-source water heater, safety, pollution is few such as the present, and are not subjected to the restriction of weather and roofing side to light position, thereby, popularize day by day in recent years.But it is many with copper that the condenser of existing air-source water heater, its condenser pipe are coil pipe, is a kind of helical form pipe, place the water body environment of internal bladder cavity, fixed by support, the vibrations that cause during compressor operating involve to coil pipe, connector is worn and torn, influence service life; Coil pipe is immersed in the water body of high temperature for a long time, the copper coil pipe of corrosion that some chemical compositions in the water have, and what have makes the copper pipe surface scaling, reduces heat conduction efficiency.Recently, the serial air-source water heater of a kind of U.S. " ease spring " is being sold by Ningbo of Zhejiang An Yuan company, the former coil pipe that places the internal bladder cavity water body is moved to outside inner bag arcwall and two end walls, in the mode of twining inner bag is wrapped up, carry out heat transmission through wall of inner container and water body,, improve heat transference efficiency for enlarging the contact area of coil pipe and inner bladder outer wall, the cambered surface of coil pipe being close to wall of inner container changes the plane into, soon is that the circular coil pipe of 0 font cross section changes the coil pipe that cross section is the D font originally.This new design has overcome the aforementioned drawback that coil pipe places water body to exist, but bring 2 new drawbacks, the one, because of coil pipe pressure-bearing work in the 2.8MPa environment, the equilibrium of circular discs inside pipe wall pressure-bearing, D shape tube damage the harmony of pressure-bearing, influence service life.The 2nd, heat transference efficiency reduced after coil pipe shifted out water body.

The utility model content

Above-mentioned deficiency at prior art, the technical problems to be solved in the utility model is that the body of designing a kind of coil pipe still keeps tubular, the body outside has fin, and coil pipe is not interposing in the water body of internal bladder cavity, and heat transference efficiency is the embedded condenser of band finned coil that improves of compensating in addition.

The technical scheme that solves the problems of the technologies described above is: the embedded condenser of this band finned coil, comprise water inlet, delivery port, shell, adiabator layer, the inner bag that is cylinder body and coil pipe, the embedding tube seat that the spiral trend is arranged on the inner bladder outer wall, the body of coil pipe has fin outward, the body of coil pipe is embedded in the embedding tube seat, fin is attached on the outer wall of inner bag, and inner bag is covered with heat-reflecting layer outward together with the finned coil pipe that embeds.

The width of embedding tube seat is slightly larger than by the outer electrical path length of embedding coil pipe, and the degree of depth slightly surpasses by the 0.5-1 of embedding coil pipe external diameter doubly.

Fin or have on two extended line directions that are distributed in the coil pipe pipe diameter, or have a slice to be distributed on the coil pipe body tangential direction.

The beneficial effects of the utility model are that the coil pipe winding is subjected to vibration effect little outside the tank, can not cause the decline of rate of heat exchange because of scaling, help energy-conservation, be not subjected to the corrosion of the chemical composition that might exist in the water, the advantage of the pressure-bearing equilibrium that the maintenance round tube has, the new design of embedding tube seat has not only improved hot transmission efficiency, also makes coil pipe strong fix on inner bag, and embedding tube seat itself plays reinforcement to wall of inner container.From the equilibrium of round tube pressure-bearing, outside twine formula shockproof, avoid the burn into wall of inner container that is set the service life that four aspects of reinforcement improve condenser.The setting up of fin and heat-reflecting layer, coil pipe go into groove embedded in addition in bury, effectively remedied coil pipe and from water body, moved to the deficiency that the heat transference efficiency that causes outside the inner bag reduces.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 and Fig. 3 are position relation signal (amplification) figure of embedding tube seat, coil pipe and fin thereof, heat-reflecting layer.

The specific embodiment

The utility model is described further below in conjunction with embodiment and with reference to accompanying drawing: with reference to Fig. 1 and Fig. 2, the shell 6 and the inner bag 9 of this condenser are cylinder body, condenser by outer and in be followed successively by the adiabator layer 7 of shell 6, polyurethane foam plastics matter, the heat-reflecting layer 8 of aluminium foil matter, copper coil pipe 4 spirals and move towards winding layer, have spiral to move towards inner bag 9 outer wall layers of embedding tube seat 2.Water inlet 1 is arranged at the bottom, delivery port 5 is arranged at top, the circular coil pipe 4 of the copper condensation of spiral trend embeds in the embedding tube seat 2, all two wall energy applying parts make every effort to be close to, therefore the width of groove 2 is slightly larger than the outer electrical path length of pipe 4, be meant under the prerequisite that can embed this groove 2, be embedded as closely making every effort to that the 0.5-1 that the degree of depth of groove 2 slightly surpasses pipe 4 external diameters doubly, this is from managing 4 degree of depth that embed, require to embed semicanal to full pipe,, then covered embedding tube seat mouth with the tangent a slice fin 3 of body if full pipe embeds, the heat-reflecting layer 8 of aluminium foil matter just can entirely coat outside the whole inner bag 9, coil pipe 4 is imbedded in the groove 2, and as shown in Figure 2, heat transfer effect is higher.Figure 3 shows that the situation that embeds nearly semicanal.The preparation method of shell 6 of the present utility model, adiabator layer 7, inner bag 9 and coil pipe 4 is a known method, water inlet 1 is a conventional structure with delivery port 5, institute's tool is improved 4 points: the one, from the internal bladder cavity water body, move to outside inner bag 9 walls coil pipe 4 and the write off support, the 2nd, changing on the inner bladder outer wall has spirality to move towards embedding tube seat 2, in order to embed coil pipe 4 and to play reinforcement, the 3rd, add the heat-reflecting layer 8, four of aluminium foil matter between adiabator layer 7 and the inner bag 9 (the band finned coil that comprises embedding), coil pipe is the coil pipe 4 that has fin 3.This four improvement have been arranged, brought foregoing beneficial effect.
