Abstract

The utility model relates to a sleeve-pipe type heat exchanger. The interior of a helical coil pipe-shaped seamless pipe is threaded with one or more copper pipes; the interiors of the copper pipes are provided with refrigerants, and water appears between the copper pipes and the seamless pipe. The utility model has the advantages of high heat efficiency, low manufacture and installation cost, simple structure and light weight, and the utility model can be used for medium-sized and small-sized household central air conditioners and can be particularly used for the small-sized household central air conditioner.

Description

Multiple tube tube-in-tube condenser, evaporimeter

The utility model relates to a kind of tube-in-tube heat exchanger.

At present, tube-in-tube heat exchanger is most effective a kind of in all kinds of heat exchangers, and usually, one or more copper pipe that is configured to of tube-in-tube heat exchanger is through in the seamless steel pipe, curves the helical disk tubulose with bending machine.By water, pass through cold-producing medium between steel pipe and the copper pipe in the copper pipe.Water and cold-producing medium reverse movement reach the purpose of heat exchange.There is following shortcoming in it: 1, be processed into difficulty of spiral coil, the cost height; 2, the anticorrosion problem of steel pipe can not finely solve; 3, for preventing the generation of condensed water, the steel pipe outside needs insulation, and insulation is difficulty, and volume increase, not easy-maintaining; The danger of bursting by freezing is arranged when 4, being used for evaporimeter; 5, relatively large central air-conditioning can only be used for, middle-size and small-size, small-sized household central air conditioning particularly can not be used for.

The purpose of this utility model is to design and a kind ofly can be used for big central air-conditioning, is more suitable for tube-in-tube condenser middle-size and small-size, particularly small-sized household central air conditioning, evaporimeter.

The utility model is achieved in that and is installed with one or more copper pipe in the seamless pipe of helical disk tubulose, is cold-producing medium in the copper pipe, is recirculated water between copper pipe and the seamless pipe.

Seamless pipe can adopt moulds copper multiple tube, aluminium plastic composited tube, PP--R pipe or U--PVC pipe.

The utility model compared with prior art has following advantage: (1), energy savings, thermal efficiency height; (2), the fabrication and installation cost is low, can reduce the cost of air conditioner greatly; (3), be used for condenser, evaporation structure is simple, and is in light weight; (4), can be used for middle-size and small-size, particularly in the small-sized household central air conditioning; (5), because the composite poor heat conductivity so be difficult for producing condensed water, does not need insulation; (6), the multiple tube inner wall smooth, less scaling.

Be elaborated below in conjunction with accompanying drawing.

Fig. 1 is the utility model front view;

Fig. 2 is the utility model vertical view;

Fig. 3 is the A-A cutaway view among the utility model Fig. 2.

As shown in Figure 1, 2, copper pipe 1 round with one or more light or the band spiral ribs penetrates in the seamless pipe 2, and hot bending becomes the helical disk tubulose.Seamless pipe 2 can adopt moulds copper multiple tube, aluminium plastic composited tube, PP--R pipe or U--PVC pipe.Two of seamless pipe 2 uses the threeway of same type of material with it to seal, middle copper pipe hermetically passing threeway.By cold-producing medium 5, pass through water 4 between copper pipe 1 and the seamless pipe 2, as shown in Figure 3 in the copper pipe 1.Cold-producing medium and water reverse movement are to reach the purpose of heat exchange.

Claims

1, a kind of multiple tube tube-in-tube condenser, evaporimeter are installed with one or more copper pipe (1) in the seamless pipe (2) of helical disk tubulose, it is characterized in that: being cold-producing medium (5) in the copper pipe (1), is water (4) between copper pipe (1) and the seamless pipe (2).

2, condenser according to claim 1, evaporimeter is characterized in that: seamless pipe (2) can adopt moulds copper multiple tube, aluminium plastic composited tube, PP--R pipe or U--PVC pipe.
