Abstract
The utility model relates to an efficient energy-saving heat exchanger. A casing thereof is in cylinder shaped, and a cylinder lid and a cylinder bottom are welded on two ends; the cylinder lid and the cylinder bottom are respectively welded with a short pipe; the inside of the casing is provided with spiral pipes which are wound into two layers by a cylinder pipe, and the spiral pipes have different diameters; two pipe joints are welded on the surface of the lower part of the casing, and a screw nut and a short pipe are respectively arranged on the two pipe joints; each of the pipe joints is connected with the two ends of each of the spiral pipes for the flow of cold water; after the short pipes on the cylinder lid and the cylinder bottom are connected with warm steam pipes, warm steam flows in the casing, and residual heat thereof makes the temperature of cold water in the spiral pipes rise to 50 DEG C; the warmed cold water flows out of the short pipes for washing clothes and baths.
Description
The utility model relates to a kind of energy-efficient heat exchanger, belongs to the technical field of hot-water supply device.
In rural area or some city, also need winter to have a bath, and wash dish at ordinary times, wash clothes, all need the hot water supply, but use electric energy or coal gas were both expensive, again consumes energy, real non-institute is suitable, small-sized warm vapour device has been used in some rural area, solves the warming problem, but does not utilize waste heat to solve the hot water supply problem.
Existing heat exchanger, several vertical tubes circulate steam in vertical tube side by side, are cold water around the vertical tube, and it is wet to utilize the waste heat of steam heat radiation in the pipe that cold water is risen, and shortcoming is bulky, and efficient is low, can not hot water without interruption, and also water temperature is also on the low side.
The purpose of this utility model is that a kind of energy-efficient heat exchanger will be provided, and it can overcome above-mentioned shortcoming, and its structure is very simple, suits practicality, is fit to general resident and uses.
The purpose of this utility model is achieved in that
A kind of energy-efficient heat exchanger, it is characterized in that housing (1) is a cylinder, two ends are welded with the cover (2) and the tube end (3) up and down, be welded with short tube (4) and (5) of band negative thread on cover (2) and the tube end (3) respectively, be equipped with in the housing (1) by copper pipe and be wound in the inside and outside different helix tube (6) of two-layer diameter, housing (1) lower surface welded pipe joint (7), refill a nut (8) and short tube (9), housing (1) surface is welded with a pipe joint (10) in addition, load onto nut (11) and screw thread short tube (12), the two ends of helix tube (6) are connected with pipe joint (7) (10) respectively.
Fig. 1 heat exchanger schematic diagram;
Fig. 2 cold water short tube and helix tube connection diagram.
Now tying the thing accompanying drawing is described in detail the structure of energy-efficient heat exchanger:
By Fig. 1,2, housing (1) is a cylinder, two ends are welded with the cover (2) and the tube end (3) up and down, cover (2) welding one short tube (4), having negative thread can be connected with warm vapour system, the tube end (3) also is welded with a short tube (5), has negative thread, also be connected with steam heating pipe, coiling helix tube (6) in the housing (1), with θ 8m/n steel pipe, at first coil the straight bigger spirality of 20 multi-turns, and the less spirality of dish play diameter, and it is superimposed in the bigger helix tube of diameter, refill a nut (8) and the short tube (9) that diameter is bigger at housing (1) lower surface welded pipe joint 7, negative thread is arranged in the pipe, tube outer surface has pin thread, same surface of shell welds a pipe joint (10) again, nut (11) and screw thread short tube (12) are housed, one end of helix tube and pipe joint (7) join, and the other end is connected with pipe joint (10), and steam heating pipe can flow in the housing (1) from short tube (41), flow out from short tube (5) again, reverse flow also can, short tube (7) is that cold water enters pipe, short tube (1) is the warm water effuser, when warm vapour flows in housing, vapor (steam) temperature is approximately 90-95 ℃, and it is wet to 50 ℃ cold water to be risen, and is flowed out by outlet pipe (10), the diet that can be used for having a bath winter washing clothes or the like also can be used to have a bath.
Compared with prior art, high-effect energy-saving heat-exchanger has following advantages:
1, take full advantage of waste heat, can save the energy, this apparatus structure is simple, can be directly and steam heating pipe connect Connect, can hot water without interruption, but do not affect original heating.
2, copper pipe makes the double-layer spiral tubular construction, and it is fast to conduct heat, also the save space area.
3, general cold water water temperature winter is 12 ℃, and be 18 ℃ summer, and through the effect of heat exchanger, leaving water temperature can reach 50 ℃.
Claims (1)
1, a kind of energy-efficient heat exchanger, it is characterized in that housing (1) is a cylinder, two ends are welded with the cover (2) and the tube end (3) up and down, be welded with short tube (4) and (5) of band negative thread on cover (2) and the tube end (3) respectively, be equipped with in the housing (1) by copper pipe and be wound in the inside and outside different helix tube (6) of two-layer diameter, housing (1) lower surface welded pipe joint (7), refill a nut (8) and short tube (9), housing (1) surface is welded with a pipe joint (10) in addition, load onto nut (11) and screw thread short tube (12), the two ends of helix tube (5) are connected with pipe joint (7) (10) respectively.
