Abstract
The utility model comprises a crust, a heating medium inlet, a heating medium outlet, a cool water inlet and a hot water outlet. The crust is provided with a core pipe. The inlet and the outlet of the heating medium are respectively sealed and welded with the inlet pipe plate and the outlet pipe plate of a heat exchanging pipe. The inlet pipe plate and the outlet pipe plate of the heat exchanging pipe are respectively provided with a plurality of pipe holes which are corresponding to each other. The numbers of the pipe holes are the same. The heat exchanging pipes are respectively provided between each corresponding pipe hole. The heat exchanging pipes are winded out of the core pipe in the multilayer spiral type. Each layer comprises a plurality of heat exchanging pipes. The heat exchanging pipes are glued to arrange in parallel. The spiral directions of the winding heat exchanging pipes of the adjacent layer are reverse. The heat exchanging pipes of the furthest inner layer are glued with the outer wall of the core pipe and a gap is between the heat exchanging pipe and the core pipe. The head exchanging pipes of the furthest outer layer are glued with the inner wall of the cylinder part of the crust and a gap is also provided between the heat exchanging pipe and the inner wall of the cylinder part of the crust. Each heat exchanging pipe layer is glued in sequence. Each heat exchanging pipe is a thin wall screw tube. The heat exchanging quotiety of the utility model can reach to 10000-14000w/m<2> DEG C . The utility model also has the advantages of small volume and light weight.
Description
Technical field
The utility model relates to heat-exchanger rig, specifically the heat exchanger in the hot water supply system.
Background technology
Heat exchanger in the hot water supply system generally is made up of the heat exchanger tube in shell, heating agent import, heating agent outlet, cooling water inlet, hot water outlet and the shell.The coefficient of heat transfer is generally at 2000W/m
2About ℃.
The utility model content
The purpose of this utility model is the higher heat exchanger of a kind of coefficient of heat transfer of design.
The utility model comprises the cylindrical housing of two ends band end socket, on the end socket of this shell the heating agent import is arranged, the heating agent outlet is arranged on another end socket, close on heating agent import department on the shell hot water outlet is arranged, close on the heating agent exit cooling water inlet is arranged, there are two ends that the core pipe of end cap is arranged in the shell, porose on the end cap, core pipe and shell have common center line, heating agent advances, exporting seal weld respectively is connected to a heat exchanger tube and advances, the outlet tube sheet, heat exchanger tube advances, on the outlet tube sheet the identical a plurality of heating agent pores in correspondence with each other of quantity are arranged respectively, between the heating agent pore of every pair of correspondence heat exchanger tube is arranged respectively, adopt Type of Welding to connect between heat exchanger tube and the tube sheet, these heat medium pipes divide the multi-layer helical formula to be wrapped in outside the core pipe, each layer all comprises a plurality of heat exchanger tubes, and these heat exchanger tubes are to paste mutually side by side to arrange, the hand of spiral that the heat exchanger tube of adjacent layer twines is opposite, the heat exchanger tube of innermost layer pastes mutually with core tube wall, and it is gapped between the two, outermost heat exchanger tube pastes mutually with the inwall of shell cylindrical portion, and it is gapped between the two, also paste mutually successively between the heat exchanger tube layer of each layer and the layer, every heat exchanger tube is all the thin-walled screwed pipe.
The coefficient of heat transfer of the present utility model can reach 10000-14000W/m
2℃.The reason that the utility model coefficient of heat transfer is so high is that the slit between heat exchanger tube is very little, and be the spirality trend, the slit of per pass spirality trend is connected again with remaining slit, will be divided into middle tortuous the flowing of the small gap of a lot of strands of weeps between heat exchanger tube after cold water is come in from import like this, form turbulent flow, mobile route is elongated, and the flow velocity of water is accelerated.Another reason is that heat exchanger tube is the thin-walled screwed pipe, and heat exchanger tube has a plurality ofly, and this attenuates each heat exchanger tube.These screw thread tubule layerings in outer cover of heat exchanger, intersection, spiral gathering cause the interior heat exchanger tube of shell to take up space and reach more than 80%, have increased heat exchange area.The technical program has not only increased the thermal efficiency, and heat exchanger volume is diminished, and weight saving is compared same output volume with general heat exchanger and can be tapered to 1/10.
Description of drawings
Fig. 1 is the cutaway view of an embodiment of the present utility model, and wherein the heat exchanger tube in the shell and the tube sheet of heat exchanger tube import and export are not analysed and observe.
