Abstract
The utility model provides a coiled pipe heat exchanger. The utility model comprises a casing, a coiled pipe arranged in the casing, a cold water inlet pipe and a cold water outlet pipe, a hot water inlet pipe, and a hot water outlet pipe, wherein, the cold water inlet pipe and the cold water outlet pipe are connected with both ends of the coiled pipe, and the hot water inlet pipe and the hot water outlet pipe are connected with the casing; the coiled pipe is coiled into at least two layers of cylindrical spiral coiled pipes form inside to outside, thin circular pipe-shaped partition plates are sheathed at the inner part of the inner layer of the coiled pipe and between the pipe layers of the coiled pipes, and one end of each partition plate is alternately connected to the wall of the casing to form a closed end, and the other end is an open end. The utility model has the advantages of long flow channel of hot water, long heat exchange time, high thermal efficiency, small heat exchange volume, and compact structure.
Description
The utility model provides a kind of heat exchanger, particularly relates to a kind of coil heat exchanger that is used for hot water machine.
At present, the developing trend high efficiency of hot water machine, the confidential compact conformation of asking of small size, especially domestic hot water, efficient height.Chinese patent CN22221199Y discloses a kind of pipe heat exchanger, and hot water inlet pipe and hot water outlet pipe are installed on the housing, is provided with the individual layer helix tube by the tubule coiling in the housing, and the two ends of helix tube communicate with cold water inlet and cold water outlet pipe respectively.Shell-side flow direction sectional area is big, and whole heat exchanger is longer, and heat exchanger effectiveness is low.
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of volume little, the coil heat exchanger that heat exchanger effectiveness is high.
The utility model coil heat exchanger is achieved in that it comprises housing, is arranged on the coil pipe in the housing, cold water inlet that is connected with the coil pipe two ends and cold water go out regardless of, and hot water inlet pipe who is connected with housing and hot water outlet pipe.Wherein, install for convenient, housing generally is made up of upper shell and lower house.Coil pipe is to be coiled into two-layer at least tubular spiral coil from the inside to the outside, generally be advisable with three layers, adopt smooth copper rounding pipe to make, its two ends are connected with the cold water outlet pipe with cold water inlet respectively, be with the dividing plate that approaches tubular in the internal layer coil pipe and between the coil pipe pipe layer respectively, for heat exchange even, the dividing plate center line should overlap fully with the coil pipe helical centre, one end of each dividing plate alternately is connected becomes blind end on the housing wall, the other end is the open end, dividing plate forms the baffling passage that is communicated with housing in the shell-side space, baffling passage two ends are connected with the hot water outlet pipe with the hot water inlet pipe respectively.Shut down or overhaul conveniently for hot water machine, can below housing, fix a drainpipe, open drainpipe, surplus water or draining-off sewage in the housing of just can draining.
The operation principle of the utility model coil heat exchanger is that during use, cold water enters from cold water inlet, after the coil pipe of flowing through carries out heat exchange, be heated to form hot water, discharge from the cold water outlet pipe, hot water flows in central partition plate (pipe) chamber from the hot water inlet pipe, after streaming, flow into successively from the inside to the outside in the interlayer cavity of dividing plate and dividing plate, stream at last in the cavity between outer dividing plate and housing wall, form repeatedly baffling, after carrying out sufficient heat exchange with cold water in the coil pipe, discharge by the hot water outlet pipe.
The advantage of the utility model coil heat exchanger is that runner increases, and heat exchanger time prolongs, thermal efficiency height, and under identical thermal power, the supporting use of coil pipe and dividing plate, the heat exchanger length-width ratio is dwindled, more compact structure.
Describe this reality in detail below in conjunction with accompanying drawing and make new embodiment.
Fig. 1: the utility model structural representation.
It comprises the housing of being made up of upper shell 1 and lower house 2 the utility model coil heat exchanger, be arranged on the coil pipe 5 in the housing, the cold water inlet 8 and the cold water outlet pipe 4 that are connected with coil pipe 5 two ends, and hot water inlet pipe 9 who is connected with housing and hot water outlet pipe 7, be installed in the drainpipe 3 on the lower house 2, coil pipe 5 is to be coiled into three layers tubular spiral coil from the inside to the outside, and three thin tubular dividing plates 6 that cover is inserted in the internal layer coil pipe 5 and coil pipe 5 is managed between the layer respectively, one end of three dividing plates 6 alternately is connected becomes blind end on the housing wall, the other end is the open end.
Claims (2)
1, a kind of coil heat exchanger, comprise housing, be arranged on the coil pipe in the housing, cold water inlet that is connected with the coil pipe two ends and cold water go out no matter, and hot water inlet pipe who is connected with housing and hot water outlet pipe, it is characterized in that coil pipe is to be coiled into two-layer at least tubular spiral coil from the inside to the outside, be with the dividing plate that approaches tubular in the internal layer coil pipe and between the coil pipe pipe layer respectively, one end of each dividing plate alternately is connected becomes blind end on the housing wall, the other end is the open end.
2, want 1 described coil heat exchanger as right, it is characterized in that the housing below is equipped with drainpipe.
