Abstract
The utility model discloses a heat exchanger for the fuel gas water heating, which is made of metal tubes. A water inlet and a water outlet are arranged on a metal tube, the metal tube adopts a corrugated tube, the metal corrugated tube is coiled into a helical tubular body in certain direction, and a water inlet and a water outlet are arranged at the both ends of the inlet and a water outlet is arranged. The heat exchanger has the advantages that the processing is easy, the cost is low, the surface area of the undulate wall of the corrugated tube is multi times of that of the smooth tube, the heating area is increased by multi times, the corrugated tube is coiled into a double-layer or multi-layer helical tubular body, the heat exchanging area can be further increased, the heat loss can be reduced, the heat exchanging efficiency of the water heater is greatly enhanced, and the heat exchanger is energy-saving.
Description
Technical field
The utility model relates to combustion gas water technical field of heating such as water heater and heating stove, particularly a kind of heat exchanger of combustion gas water heating.
Background technology
At present, normally tubular or oval metal tube of the heat exchanger of existing gas heater on the market, material generally has copper pipe, aluminum pipe or other metal tube, metal tube curves U-shaped or straight tube is alternately in parallel with bend pipe, water flows into from the water inlet of metal tube one end, flow out from the delivery port of the other end, water is heated in pipe and flow to the delivery port outflow then.Because the tube wall of round metal tube is the light face, its heat exchange area is less relatively, is used for increasing heating surface area though metal tube curves U-shaped as far as possible, but volume restrictions because of water heater, heat exchange effect is still not ideal enough, and the heat exchanger effectiveness of water heater is not high, and heat-energy losses is more.
The utility model content
At the deficiency of above existing water heater, the purpose of this utility model provides a kind of heat exchanger of combustion gas water heating, can increase the endotherm area of heat exchanger, improves the water heater thermal efficiency.
The purpose of this utility model is achieved by the following technical solution:
A kind of combustion gas water reheat heat exchanger, mainly made by metal tube, be provided with water inlet and delivery port on metal tube, described metal tube is a bellows, metal bellows turns to the helical tubular body by certain orientation, and the two ends of metal bellows are made as water inlet and delivery port.
As optimal technical scheme of the present utility model, described metal bellows turns to the helical tubular body by dextrorotation direction or derotation direction, and described water inlet and delivery port are located at an end of helical tubular body simultaneously.
As optimal technical scheme of the present utility model, described helical tubular body is made as at least two circles or more than two circles, water inlet and delivery port are located at an end of helical tubular body simultaneously.
As optimal technical scheme of the present utility model, described metal bellows can be round tube, rectangular tube or other special pipe, and its tube wall ripple can be helical fissure, annular corrugated or other waveform ripple.
As optimal technical scheme of the present utility model, described metal bellows is circular corrugated stainless steel tubing, and corrugated stainless steel tubing turns to the two-layer helical tubular body with outer ring and inner ring, and water inlet and delivery port are located at an end of helical tubular body simultaneously.
The beneficial effects of the utility model are: by above structure as can be known, the surface area of bellows waveform tube wall is the several times of smooth pipe surface area, its heating surface area promptly increases several times, bellows is turned to the helical tubular body of bilayer or multilayer, can further increase heat exchange area, reduce heat-energy losses, greatly improve the heat exchanger effectiveness of water heater.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Fig. 1 is that the master of the utility model double-layer spiral shape bellows heat exchanger looks schematic diagram;
Fig. 2 is the schematic perspective view of Fig. 1;
Fig. 3 is the local structure for amplifying schematic diagram of A place bellows among Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of combustion gas water reheat heat exchanger, make by circular corrugated stainless steel tubing, corrugated stainless steel tubing turns to double-layer spiral shape tubular body by dextrorotation direction or derotation direction, double-layer spiral shape tubular body is made of outer ring 1 and inner ring 2, the water inlet 4 of heat exchanger and delivery port 3 are located at an end of helical tubular body simultaneously, and the ripple of circular corrugated stainless steel tubing is a helical fissure, and helical fissure is made of crest 5 and trough 6.
Among the embodiment of the present utility model, described corrugated stainless steel tubing also can be square corrugated pipe, oval ripple pipe or other special-shaped bellows, and their tube wall ripple can also be annular corrugated, zigzag ripple or other waveform ripple.Water enters the inner ring 2 of flowing through from water inlet 4,1 delivery port that flows to appointment through the outer ring again, the thermal source burner is located at the central part of inner ring 2, and each forms the heating clamber that seals with the temperature-resistant material sealing two ends, and burner heat energy passes from the waveform gap of bellows, discharge after finishing heat exchange, be characterized in that heat exchange area is big, heat exchanger effectiveness height, handling ease, cost is low, is very energy-conservation heat exchanger.
Claims (5)
