Abstract
The utility model relates to a volume floating coil tube heat exchanger. The inner part of a tank body is provided with multi-layer floating coil tubes. Two ends of the floating coil tube are respectively fixed and connected with a heating medium input steam main and a condensation return pipe. The utility model is characterized in that the upper part of the inner part of the tank body is provided with a tension spring and a floating ball; the upper end of the tension spring is fixed on the sealed head of the tank body; the lower part of the tension spring is connected with each layer of the floating coil tubes by using elastic strings; the lower end of the floating ball is provided with elastic strings which are connected with each layer of the floating coil tubes. The multi-layer floating coil tubes are welded with horizontal metal nets. The utility model has the advantages that the utility model modal can eliminate the fouling of the floating coil tubes, increase the flow rate and the winding movement of the chilled water, and enhanced the heat exchange effect. The utility model is suitable for hot water supply systems with different heating mediums such as the seam, the high temperature hot water, etc.
Description
The utility model belongs to the not direct heat-exchange apparatus of contact of heat exchange medium, but particularly a kind ofly is provided with the floating coiler heat exhanger that move upper and lower, left and right in the volumetric heat exchanger housing.
At present, in industry and the domestic hot-water of civil buildings, air conditioning hot, heating hot water supply system, its fixed U-shaped coil pipe upright, all employing levels of volumetric heat exchanger that crouch carries out heat exchange, be that heating agent passes through to flow in the parallel coil pipe pipe, carry out heat exchange with the heated chilled water of housing inner coil pipe outer wall.The weak point of its existence is, heated chilled water is big because of the volumetric heat exchanger flow area in the housing, and water velocity is very low, thereby the heat exchanger heat transfer COEFFICIENT K is less, and the thermal efficiency is low.Simultaneously, in the process of carrying out heat exchange, the thicker dirt of long-pending knot on the U-shaped coil pipe outer wall is because the U-shaped coil pipe maintains static, dirt is easy-clear not, and the dirt that sticks to U-shaped coil pipe outer wall can not come off automatically yet, moreover, after heating agent flows through the U-shaped coil pipe, condensing water temperature height, waste heat energy.
The purpose of this utility model is, in the tank body of multilayer floating coiler heat exhanger, spring and ball float is set, and to affect fluctuating of floating coiled pipe, plays the effect of removing incrustation on the coil pipe; Deflector and wire netting are set,, strengthen the heat exchange effect to increase refrigerant flow rate and disturbance.
The utility model positive displacement floating coiler heat exhanger, advancing steam main, condensate return main, refrigerant water inlet pipe, hot water outlet pipe, blow-off pipe by tank body, floating coiled pipe, heating agent forms, in tank body, be provided with the multilayer floating coiled pipe, the floating coiled pipe two ends advance steam main with heating agent respectively and condensation return pipt is connected to a fixed, it is characterized in that, be provided with extension spring and ball float at the tank body internal upper part, the extension spring upper end is fixed on the pot body closing end, bottom and each layer floating coiled pipe link with the elasticity cord, the ball float lower end is provided with the elasticity cord, is connected with each layer floating coiled pipe; Be provided with the horizontal anti-short circuit baffle plate of multilayer at the tank body inner rim, advance to be provided with the horizontal deflector of multilayer between steam main and the condensation return pipt, on the multilayer floating coiled pipe, be welded with the horizontal metal net at heating agent.
The using method of positive displacement floating coiler heat exhanger of the present utility model is, cold water enters the bottom of tank body by the refrigerant water inlet pipe, after the multilayer floating coiled pipe is heated, flows out from tank body top, delivers to the user; The heating agent that boiler produces advances steam main by heating agent, branches to the multilayer floating coiled pipe again, by tank body cold water cool, after the exchange heat, steam becomes condensate water, flows out tank body by the condensate return main again, flows back to boiler; After in boiler, being heated, be sent again, so repeatedly circulation.
Because floating coiled pipe is heated to produce under the current impulsion of water in tank body and is fluctuated, and when heating agent flowed in the floating coiled pipe, the disturbance of floating coiled pipe retractable made floating coiled pipe be heated water outward and is under the disturbance, become turbulent flow by laminar flow, increased heat-transfer effect.
Owing to be provided with spring and ball float in the tank body, interrelate with each layer floating coiled pipe, can prevent that floating coiled pipe is sagging excessive because of conducting oneself with dignity, cause that the floating coiled pipe junction fractures; Simultaneously, can make coil pipe under the current impulsion.Strengthen disturbance, improve heat-transfer effect.
Anti-short circuit baffle plate and deflector in the tank body, flow velocity improves in the time of can making chilled water flow through floating coiled pipe, and heat transfer efficiency increases; Wire netting and floating coiled pipe weldering connection one, similar coil pipe outer wall rib increases heat transfer area, because the obstruct of wire netting can increase the chilled water flow velocity, strengthens the chilled water flow disturbance, strengthens heat-transfer effect.
The utility model has the advantages that, can eliminate incrustation on the floating coiled pipe, increase chilled water flow velocity and disturbance.Strengthen heat-transfer effect.Be applicable to the heat exchange of steam, high-temperature-hot-water, the different heating agents of low-temperature water heating, can be used for domestic hot-water, air conditioning hot, the heating hot water supply system of various buildings.
Below in conjunction with drawings and Examples, the utility model is further described.
