Description
Affiliated technical field
The utility model relates to the heat-exchange device in a kind of heating and the hot-water heating system, and particularly a kind of is the heating of thermal source and domestic hot water's two-tube heat exchanger with combustion gas.
Background technology
In the northern area of China, winter cold and time are long, and indoor heating is created and a home from home that improves people work, life is very important.At present collective's heating systems that adopt more, to the heating of room areas such as dwelling house, cubicle, building for commercial use, be thermal source with coal or fuel oil, generally be by unit or special heating company, unified heating in official hour, heating mechanism is dumb, and heating duration can not and be grasped by user oneself control, and the pipeline that connects each user is very long, and be exposed at the outdoor of cold, cause a large amount of losses of heat,, can only reduce some heat leakages though can take the wrapping measure.
Summary of the invention
The purpose of this utility model just is to overcome the central heating deficiency, and providing a kind of is the two-tube heat exchanger of thermal source with the combustion gas, and user oneself grasps and controls heating duration and the domestic hot-water is provided.
The utility model technical solution is: a kind of two-tube heat exchanger, comprise the heat collector that fin (5), interior pipe (6), outer tube (7) constitute, it is characterized in that: be communicated with 5 tube connectors (11) by pipe (6) in 6, left port of pipe 6.1 is that water inlet is communicated with water inlet halter (2) in first, the other end of water inlet halter (2) is communicated with the water source, the left side mouth of pipe 6.6 is that delivery port is communicated with water out adapter (1) in last root, and the other end of water out adapter (1) is communicated with the domestic water halter; Wherein three 7.1,7.2 of 6 outer tubes (7), 7.3, right output port is connected with the right water box (10) of two water boxes, its left side is communicated with single water box (3), and an end of water inlet halter (9) is communicated with other three outer tubes 7.4 with water source, recirculated water, 7.5,7.6, left port be communicated with single water box (3), right output port is communicated with the left water box (13) of two water boxes, one end of water outlet halter (8) is communicated with two water box left side water boxes (13), and the other end of water outlet halter (8) is communicated with warming installation.
The beneficial effects of the utility model are: realized with the combustion gas being the heating of thermal source and the heat exchange of domestic water, heating and confession domestic water time are grasped and control by user oneself, and this two-tube heat exchanger has the rate of heat exchange height, and is simple in structure, easy to use, reduce advantages such as heat leakage.

The specific embodiment
Below with reference to the accompanying drawing description detailed in addition to the utility model:
As shown in Figure 1: five tube connectors of pipe 6 usefulness 11 are communicated with in the six roots of sensation, the two ends oral area outer rim ovalize of interior pipe 6, so that be communicated with oval tube connector 11 welding, left port of pipe 6.1 is that water inlet is communicated with water supply connector 2 in first, the other end of water supply connector 2 is communicated with the water source, the left port of pipe 6.6 is that delivery port is communicated with water out adapter 1 in last root, and the other end of water out adapter 1 is connected with domestic water tap, bathing shower nozzle etc., constitutes the domestic water passage.Six roots of sensation outer tube 7, wherein three 7.1,7.2,7.3 right output port is connected with the right water box 10 of two water boxes, its left side is communicated with single water box 3, one end of water supply connector 9 is connected with the right water box 10 of two water boxes, the other end of water supply connector 9 is communicated with water source, recirculated water, other three outer tubes 7.4,7.5,7.6 left port be communicated with single water box 3, right output port is communicated with the left water box 13 of two water boxes, and an end of water out adapter 8 is communicated with two water boxes left side water box 13, and the other end of water out adapter 8 is communicated with warming installation, as radiator, constitute heating aquaporin.Heat collector mainly is to be welded as a whole by several pieces fins 5 and the several outer tube 7 that are through outer tube 7, absorption is from the heat of heat source gas, realize heat exchange, water temperature in outer tube 7 and the interior pipe 6 is improved, obtain life hot water and heating hot water, and reach the purpose that obtains domestic water and heating by domestic water passage and heating aquaporin.For reaching high rate of heat exchange, as shown in Figure 2, fin 5 is deposited welding rod by depositing welding rod aperture 12, and fin 5 and outer tube 7 are welded as a whole, thermal conduction effect is better, for this reason, fin 5 adopts the higher oxygenless copper material of heat conduction efficiency to make, and the quantity of fin 5 can be decided as required, the length of interior pipe 6 and outer tube 7 also can increase or shorten as required.Interior pipe 6 cross sectional shapes, cross as shown in Figure 3, four circular protrusions of interior pipe 6 outer wall cross, these four are raised to rare three places projection and closely contact with the inwall of outer tube 7.Advantages such as what the utility model provided is the two-tube heat exchanger of thermal source with the combustion gas, has the rate of heat exchange height, simple in structure, easy to use, user oneself grasps, and the control heating, for the time of life with hot water.
