Abstract

The utility model discloses a heat accumulation type heating heat exchanger, which is processed from a stainless outer pipe and a thin-walled stainless steel spiral inner pipe, wherein, the inner pipe adopting an S-shaped complete pipe through reciprocating bending, the outer pipe adopts a round pipe with a 45-degree slanted opening, the heat exchanger formed by first sleeving the inner pipe into the outer pipe, then butt-welding the inner and the outer pipes, and finally welding in a hermetically sealed manner the seams on the head and the tail of the inner pipe and the outer pipe, and a water inlet interface and a water outlet interface are welded respectively at the heat and the tail of the inner pipe and the outer pipe. With a large surface area, the spiral inner pipe of the utility model increases the heat exchange area and improves the efficiency in heat exchange. Moreover, because of being bent integrally at one attempt rather than being connected in the middle, the spiral inner pipe can be bent freely, thereby prolonging the service life and reducing the risk of internal leakage. The stainless steel outer pipe has the advantages of large strength, light weight and attractive appearance.

Description

Heat storage type heating heat-exchange device

Technical field

The utility model relates to heat transmission equipment, and this heat exchanger is applicable to and utilizes the displacement bathing domestic hot-water of domestic heating system.

Background technology

At present, bathing that the resident uses winter and domestic hot-water mainly contain two kinds of approach: the one, and utilize firing equipment that hot water is provided specially, as solar water heater, gas heater, electric heater etc.; The 2nd, utilize the hot water of heating system to displace hot water.Replacing apparatus mostly adopts common Instant heating type heat transmission equipment, and it is in the cast iron flush cistern of a sealing coil pipe to be set, and coil pipe is fully immersed in the hot water, when cold water flows through coil pipe and carry out heat exchange.Though this heat exchanger can keep certain leaving water temperature, build is relatively heavier, and volume is bigger, and the coil pipe internal surface area is less, and heat exchange efficiency is low.

Summary of the invention

For overcoming the deficiencies in the prior art, the utility model provides the heat storage type heating heat-exchange that a kind of build is light, heat exchange efficiency is high device.

For achieving the above object, the utility model adopts following technical scheme: this heating heat storage type heat exchanger is processed by pipe in stainless steel outer tube and the thin-wall stainless steel spiral, wherein in pipe for whole pipe, it is to be bent into back and forth S shape by a pipe; Outer tube is the pipe of 45 ° of angles of a joint joint, and cover back head and the tail butt welding on inner pipe is connected into heat exchanger integral body, then with the initial and end place gap welded closure of outer tube and interior pipe, and water-in and water-out interface in the head and the tail welding of outer tube and interior pipe respectively.

During use, the outer tube water inlet connects running water, delivery port connects water pipe; Interior water inlet tube mouth and delivery port are connected in the heating water pipe.

Good effect of the present utility model is: spiral interior tube body surface area is big, has increased heat exchange area, has improved heat exchange efficiency; Pipe is convenient to random bending in spiral, whole bending forming, and middle no interface has prolonged service life, has reduced internal leak.

The specific embodiment

Describe structure of the present utility model in detail below in conjunction with accompanying drawing.

As shown in Figure 1, it is to be processed by pipe 2 in all steel outer tube 1 and the thin-wall stainless steel spiral.Wherein pipe 2 is that a homogeneous tube is bent into the S shape back and forth in the thin-wall stainless steel spiral; Outer tube 1 intercepts into a joint joint transverse tube a and an end pipe b according to the design width of hot-water line and the height of bending place, during intercepting, angle at 45 is cut at two ends, again a joint transverse tube a and a joint end pipe b alternately are arranged on the interior pipe 2, pipe 2 in the cover outer tube 1 spring folding of limit, to the angle butt joint of transverse tube a and end pipe b, adopt welding manner to be welded into integral body simultaneously.Weld hot water outlet 3 at the head place of outer tube then, cooling water inlet 4 is gone up in the tail place welding of outer tube; Heating water inlet 5 is welded at the head place of interior pipe, and heating delivery port 6 is gone up in the welding of tail place.The heat exchange principle is: life cold water enters outer tube 1 and interior pipe 2 interlayers by cold water inlet 4, through S type route, flows out from hot water outlet 3; Heating is supplied water and is flowed into from heating water inlet 5, flows out from heating delivery port 6 by interior pipe 2.In this process, heating water and cold water constantly carry out the heat effect and change, and heating water turns cold gradually, and life cold water is heating gradually, thereby reaches the heat exchange purpose.When not using the domestic hot-water, cold water is stored between outer tube 1 and interior pipe 2 interlayers, and heating water continues to flow, and cold water continues heat exchange and finally reach temperature consistent with heating water, this moment, heat exchanger can be used for carrying out heating, and the hot water of steady temperature can be provided when use the domestic hot-water next time simultaneously.

Claims

1. a heat storage type heating heat-exchange device is characterized in that, it is to be processed by pipe in stainless steel outer tube and the thin-wall stainless steel spiral, wherein in pipe for whole pipe, it is to be bent into back and forth S shape by a pipe; Outer tube is the pipe of 45 ° of angles of a joint joint, and cover back head and the tail butt welding on inner pipe is connected into heat exchanger integral body, then with the initial and end place gap welded closure of outer tube and interior pipe, and water-in and water-out interface in the head and the tail welding of outer tube and interior pipe respectively.
