Abstract
The utility model relates to an intensified heat transmission corrugated pipe heat-exchanger, comprising a barrel body of a heat exchanger, a channel box divided into an upper cavity and a lower cavity by a baffle plate arranged on one end of the heat exchanger, a water outlet communicating with the lower cavity of the channel box, a water inlet communicating with the lower cavity of the channel box, a corrugated heat exchanger communicating with the lower cavity and the lower cavity of the channel box arranged in the barrel body of the heat exchanger, an end plate cavity communicating with the other end of the corrugated heat exchanger, a steam inlet arranged on the upper end of the barrel body of the heat exchanger and a condensation water outlet arranged at the lower end of the barrel body of the heat exchanger. The utility model causes the fluid on the outside of the corrugated heat exchanger to perturb violently, increases heat emission coefficient, meanwhile increases heat exchange, the utility model cancels general baffle board in the prior heat exchanger, and cancels a tie bar, thereby saving materials.
Description
Technical field
The utility model relates to a kind of augmentation of heat transfer corrugated tube heat exchanger.
Background technology
Corrugated tube heat exchanger strengthens stirring in order to make the fluid outside pipe at present, installs deflection plate in heat exchanger additional, makes the stronger stirring of extratubal fluid, increase heat transfer coefficient, thereby increase heat output, heat exchanger efficiency is improved, this kind heat exchanger structure complexity take material, and the thermal efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of thermal efficiency height, augmentation of heat transfer corrugated tube heat exchanger simple in structure.
The utility model adopts following technical scheme:
The utility model comprises the heat exchanger cylindrical shell, be arranged on being separated into water inlet that the lower chamber of water out that the upper cavity of the bobbin carriage in two chambeies up and down and bobbin carriage is connected and bobbin carriage is connected, being arranged on node heat exchanger tube, the end socket cavity that is communicated with the node heat exchanger tube other end that in the heat exchanger cylindrical shell and cavity up and down bobbin carriage be connected, the condensate water outlet that is arranged on the steam inlet of heat exchanger cylindrical shell upper end and is arranged on heat exchanger cylindrical shell lower end by dividing plate of heat exchanger cylindrical shell one end.
The crest of node heat exchanger tube described in the utility model and the height between the trough are 8-12mm.
The utility model is provided with impingement baffle in the inboard of steam inlet.
The utility model good effect is as follows: what the heat-transfer pipe of the utility model corrugated tube heat exchanger adopted is that the thin-wall stainless steel bellows is the node heat exchanger tube, the about 10mm of height between its crest and the trough, for making node heat exchange tube outer fluid strong agitation, can utilize the height between the trough, it is controlled in the up-to-date scope, node heat exchange tube outer fluid is thrown moving with crest, the utility model can make the outer strong disturbance of fluid of node heat exchange tube, increase heat transfer coefficient, also increased the ring heat simultaneously.
The utility model has been cancelled deflection plate commonly used in the existing heat exchanger, has also cancelled pull bar simultaneously, has saved material.
Description of drawings
Accompanying drawing is the utility model structural representation
In the accompanying drawings: 1 bobbin carriage, 2 water outs, 3 flanges, 4 tube sheets, 5 steam inlets, 6 impingement baffles, 7 heat exchanger cylindrical shells, 8 node heat exchanger tubes, 9 exhaust outlets, 10, pad, 11 end socket cavitys, 12 studs, 13 nuts, the outlet of 14 condensate water, 15 bearings, 16 sewage draining exits, 17 dividing plates, 18 water inlets.
The specific embodiment
The utility model comprises heat exchanger cylindrical shell 7, what be arranged on heat exchanger cylindrical shell 7 one ends is separated into the bobbin carriage 1 in two chambeies up and down by dividing plate 17, the water out 2 that is connected with the upper cavity of bobbin carriage 1, the water inlet 18 that is connected with the lower chamber of bobbin carriage 1, be arranged on the node heat exchanger tube 8 that the cavity up and down with bobbin carriage 1 in the heat exchanger cylindrical shell 7 is connected, the end socket cavity 11 that is communicated with node heat exchanger tube 8 other ends, the condensate water outlet 14 that is arranged on the steam inlet 5 of heat exchanger cylindrical shell 7 upper ends and is arranged on heat exchanger cylindrical shell 7 lower ends, the crest of described node heat exchanger tube 8 and the height between the trough are 8-12mm, are provided with impingement baffle 6 in the inboard of steam inlet 5.
The utility model is when heat exchange, cold water is entered by water inlet 18, discharge by water out 2, steam the shell side side enter from steam inlet 5 heat exchanger cylindrical shell 7 in node heat exchanger tube 8 in cold water finish heat exchange, discharge by condensate water outlet 14 after the condensation, thereby finish heat exchange.
The utility model corrugated tube heat exchanger mainly utilizes the bellows of thin-walled to conduct heat.Highly about 10mm between its crest and the trough when fluid is mobile in node heat exchanger tube 8 pipe, outside the pipe, all produces strong stirring, even also can make fluid flow state reach abundant turbulent flow under the very low situation of flow velocity.The utility model can make the outer strong disturbance of fluid of node heat exchanger tube 8 pipes, increases heat transfer coefficient, has also increased the ring heat simultaneously.
