Heat exchanger ordinary construction complexity used in prior art, the connection preparation between parts realizes by solder technology.The shortcoming of this heat exchanger is that easily leak at the positions such as welding, and complex structure.
Summary of the invention
In order to overcome the weak point of easily leakage of heat exchanger used in existing HTHP circulation, complex structure, making trouble, the utility model provides a kind of heat exchanger, this heat exchanger is not only prone to leakage, and simple for production, simple in structure, with low cost.
The technical scheme that the utility model adopts is:
For a heat exchanger for HTHP circulation, comprise hot water interior conduit and cold water Outer Tube, described hot water interior conduit is arranged among the outer pipeline of cold water; Wherein: the two ends of described cold water Outer Tube are respectively by the supervisor of the described threeway straight-through one end of described reducing that is tightly connected, the straight-through other end of the reducing described hot water interior conduit that is tightly connected; The two ends of described cold water Outer Tube are by the arm of described threeway be tightly connected respectively cold water inlet and cooling water outlet.
Described hot water interior conduit is arranged among the outer pipeline of cold water, and its two ends lead directly to and stretch out outside reducing direct piping through threeway supervisor and reducing.
Described hot water interior conduit and cold water Outer Tube are stainless-steel seamless pipe.
On two arms of described threeway, be tightly connected respectively stainless-steel seamless pipe as cold water inlet and cooling water outlet; The internal diameter of cold water inlet and cooling water outlet is identical with the internal diameter of cold water Outer Tube.
Described being tightly connected refers to by cutting ferrule and connects.
If any insulation requirement, can be at this device outer wall parcel one layer of heat preservation cover.
Described stainless-steel seamless pipe is 316 stainless steels.
The utility model principle is as follows:
The utility model cold water enters cold water Outer Tube from cold water inlet, flows out cold water Outer Tube from cooling water outlet, the hot water that flows in hot water interior conduit, and hot water flow direction is contrary with cold water flow direction.Realize hot conduction by inner pipe wall, hot water is turned cold, cold water heating, thus realize hot exchange.
The beneficial effects of the utility model are:
1, the utility model is led directly to and is conveniently realized building of heat exchanger by stainless steel tube, threeway, reducing, and has avoided the easy leakage positions such as welding.
2, the utility model can improve heat exchanger effectiveness by the stainless steel tube that uses longer dimension.
3, between the large specification stainless steel pipes of the utility model (being cold water Outer Tube) and threeway, threeway and perforation reducing straight-through between, perforation reducing straight-through with small dimension stainless steel pipes (hot water interior conduit) between, be all to connect by cutting ferrule, convenient and reliable.
4, in the present invention, stainless-steel seamless pipe is 316 stainless steels, 316 stainless steel high temperature high voltage resistant aqueous corrosions, and also intensity is good, can meet operation for a long time under experiment condition.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-hot water interior conduit; 2-cold water Outer Tube; 3-threeway; The supervisor of 31-threeway; The arm of 32-threeway; 4-reducing is straight-through; 5-cold water inlet; 6-cooling water outlet.
Detailed description of the invention
As shown in Figure 1, the utility model is to form by two kinds of different size pipelines, the threeway being tightly connected with cutting ferrule, the straight-through establishment of reducing that be tightly connected with cutting ferrule for the heat exchanger of HTHP circulation.Specifically comprise hot water interior conduit 1 and cold water Outer Tube 2, described hot water interior conduit 1 is arranged among the outer pipeline 2 of cold water; The two ends of described cold water Outer Tube 2 are respectively by be tightly connected one end of described reducing straight-through 4 of the supervisor 31 of described threeway, the other end of the reducing straight-through 4 described hot water interior conduit 1 that is tightly connected, the two ends of described hot water interior conduit 1 are through supervisor 31 and the reducing straight-through 4 of threeway and stretch out outside straight-through 4 pipelines of reducing.The two ends of described cold water Outer Tube 2 are tightly connected respectively one section of stainless-steel seamless pipe as cold water inlet 5 and cooling water outlet 6 by the arm 32 of described threeway, and the internal diameter of cold water inlet 5 and cooling water outlet 6 is identical with the internal diameter of cold water Outer Tube 2.Described hot water interior conduit 1 and cold water Outer Tube 2 are stainless-steel seamless pipe.
Described being tightly connected refers to by cutting ferrule and connects.If any insulation requirement, can be at this device outer wall parcel one layer of heat preservation cover.
Above-mentioned heat exchanger preparation process is as follows:
Hot water interior conduit adopts small dimension stainless-steel seamless pipe, and cold water Outer Tube adopts large specification stainless-steel seamless pipe, and wherein small dimension hot water interior conduit grows a part than large specification cold water Outer Tube, can reserve threeway and the perforation straight-through space of reducing are installed.Two with the stainless steel threeway of the large corresponding model of specification steel pipe, the stainless steel perforation reducing of two size specification conversions leads directly to.
