Description

Node pipeline section floating coiler heat exhanger

The utility model relates to heat exchanger, and particularly a kind of horizontal floating coiled pipe that utilizes the node pipeline section to make carries out the heat exchanger of augmentation of heat transfer.

General floating coiler heat exhanger has saved tube sheet on the whole owing to less scaling, has simplified the structure of heat exchanger, therefore rather well received on market, but general floating coiler heat exhanger, owing to there is the part slough, cold water does not from bottom to top contact with heat exchanger tube, and heat exchange is incomplete; And, with the floating coiled pipe that general thick walled steel tube or copper pipe are made, further improve quite difficulty of its heat transfer coefficient.

The purpose of this utility model is to provide a kind of thermal efficiency height, does not have the novel node pipeline section floating coiler heat exhanger of slough.

The node pipeline section floating coiler heat exhanger of the utility model design comprises a housing that has upper shell cover and lower cover, the top of described upper shell cover is provided with the hot water outlet pipe, a side is provided with the cooling water outlet pipe on the described lower cover, central authorities are provided with vertical central tube in housing, the two ends of described central tube are provided with circular flat cover, be provided with the vertical clapboard that central tube is divided into two in the pipe, and the lower end of central tube is outside lower cover stretches out housing, and the both sides of corresponding dividing plate are respectively equipped with heating agent inlet tube and heating agent outlet on the central tube outside stretching out housing; Central tube in described housing is other to be provided with the different-diameter of several row of horizontal but the C font coil pipe of concentric, the two ends of each coil pipe on the same plane communicate with its isoplanar two headers respectively, described header links to each other with central tube, and is separately positioned on the both sides of dividing plate.

Wherein, described coil pipe can be circular arc node coil pipe.

The position that is provided with of the header of the horizontal coil pipe between the described two rows can rotary shifted mutually 180 ° of angles.

The design feature of the node pipeline section floating coiler heat exhanger of the utility model design is that the coil pipe of the different-diameter made by stainless-steel thin-wall pipe all covers cross section in the housing, the space that coil pipe does not cover from bottom to top, do not stay the slough, so heat exchange is more even effectively; Horizontal coil pipe adopts the isocentric circular arc connected mode, vertical direction does not have constraint, help current and from bottom to top coil pipe is produced active force, coil pipe is produced to float, coil pipe floats and again current is produced local dip, strengthened heat transfer, because floating coiled pipe adopts the node pipeline section, make outer fluid strong disturbance of generation under low flow condition in the pipe, reached abundant turbulent flow, not only destroyed the boundary layer but also washed away the boundary layer, bellows tube has adopted the design of ultra-thin-wall, therefore heat transfer coefficient is very high, has remarkable energy saving effect.

The course of work of the node pipeline section floating coiler heat exhanger of the utility model design is: heating agent enters the side drain flow path that central tube and dividing plate surround by inlet tube, and enters respectively to arrange in a row more and flow in the horizontal floating coiled pipe of tube wave pipe joint section; Heat release is carried out after the heat exchange in coil pipe, introduce in second half runner that central tube and dividing plate surround by another root header, draw through the heating agent outlet again, be heated the cold water inlet tube importing of water by lower cover, flow from bottom to top, be heated the back and flow out by the hot water outlet pipe who is arranged at upper shell cover.

Compared with prior art, the node pipeline section floating coiler heat exhanger of the utility model design has made full use of the high advantage of thin-walled bellows tube heat transfer coefficient, and it can further be brought into play the advantage of floating coiled pipe as the pipeline section of floating coiled pipe; Utilize the housing center that central tube is set simultaneously, and central tube is divided into two semicanals as heating agent outlet and inlet, avoided the slough that occurs on the common structure, help the exchange of heat, improved the heat energy utilization rate, it is superior to have heat exchange property, the heat transfer efficiency height, automatic desludging, supply water steadily, there is not the slough, current can not be short-circuited, simple in structure, characteristics such as operating maintenance is convenient, be applicable to that heating agent is different heating agent operating modes such as high low-temperature water heating and steam, can be used for heating system, the domestic hot-water of industry and civil buildings, idle call hot water etc., the scope of application is extensive.

Further describe the utility model below in conjunction with accompanying drawing.
