Abstract
The utility model discloses a large volume sleeve pipe type heat-exchanger used for water chilling units, comprising two screw sleeve pipes, namely, an upper screw sleeve pipe and a lower screw sleeve pipe, wherein, water inlet pipes of the lower screw sleeve pipe are connected to water inlet pipes of the upper screw sleeve pipe through an extension pipe; water outlet pipes of the upper screw sleeve pipe are connected to water outlet pipes of the lower screw sleeve pipe through another extension pipe. The utility model can increase heat exchanging areas and the volumetric capacity of medium to two times under the conditions that the numbers of elbows and the space occupation areas are not increased. The power of air conditioning sets can accordingly increase to two times when the utility model is used for air conditioning sets.
Description
The utility model relates to the big capacity double-tube heat exchanger that a kind of handpiece Water Chilling Units is used.
Heat exchanger is a requisite vitals in the air conditioner, and the refrigeration or the heating efficiency of air-conditioning unit had crucial effects.Screw-casing tubular type heat exchanger commonly used in small-sized heat pump air conditioner unit, this heat exchanger is owing to compact conformation, heat exchange efficiency height are widely used.Resistance is bigger but the shortcoming that this spiral tube heat exchanger exists is exactly a medium when flowing in interior pipe, therefore is not suitable for relatively large air-conditioning unit.If adopt to increase the diameter of sleeve pipe or prolong sleeve pipe length way and be applied on the large-scale air-conditioning unit not only uneconomical economically and also can since the increase of casing diameter and significantly increase unit volume or can elbow quantity increases because the increase of casing length make, the increase of the resistance of media flow, cause the lubricating oil return difficulty, not only influence the service life that heat exchange efficiency also can influence compressor.
The purpose of this utility model provides a kind of big capacity double-tube heat exchanger that can be used for the air-conditioning unit of larger capacity.
For achieving the above object, the technical solution adopted in the utility model is as follows:
Liquid-dividing head and water inlet pipe that is connected to the screw shell two ends and outlet pipe that big capacity double-tube heat exchanger described in the utility model comprises screw shell, is connected with interior pipe in the screw shell by separating tube, be characterized in: this big capacity double-tube heat exchanger comprises two screw shells, promptly go up screw shell and following screw shell, the water inlet pipe of following screw shell prolongs pipe by one and is connected on the water inlet pipe of screw shell; The outlet pipe of last screw shell prolongs pipe by one and is connected down on the outlet pipe of screw shell; The separating tube that is connected with liquid-dividing head is connected on the tube sheet of screw shell and following screw shell; The female pipe outlet of the refrigerant of last screw shell and following screw shell links together by a three-way pipe.
After adopting technique scheme, big capacity double-tube heat exchanger described in the utility model is applied to correspondingly can make on the air-conditioning unit power of air conditioner group to double not increasing floor space, not increasing under the situation of elbow quantity the capacity of heat exchange area and medium is doubled.
Further specify the utility model below in conjunction with drawings and Examples:
Fig. 1 is the front view of an embodiment of the present utility model;
Fig. 2 is the right view of Fig. 1 embodiment;
Fig. 3 is the vertical view of Fig. 1 embodiment.
As Fig. 1, Fig. 2, shown in Figure 3, liquid-dividing head 3 and water inlet pipe that is connected to the screw shell two ends and outlet pipe that big capacity double-tube heat exchanger described in the utility model comprises screw shell, is connected with interior pipe in the screw shell by separating tube, screw shell has two, promptly go up screw shell 1 and following screw shell 2, the water inlet pipe of following screw shell 2 prolongs pipe by one and is connected on the water inlet pipe 4 of screw shell 1; The outlet pipe 5 of last screw shell 1 prolongs pipe by one and is connected down on the outlet pipe of screw shell 2.All there is tube sheet at the two ends of last screw shell 1 and following screw shell 2, and the two ends of interior pipe are connected on the tube sheet, and the inlet of interior pipe is connected with liquid-dividing head 3 by separating tube, and the outlet of interior pipe is connected on the tube sheet of screw shell 1 other end, and formation is the female pipe outlet 10 of refrigerant.Last screw shell 1 be the female pipe outlet 10 of refrigerant with play screw shell 2 be that the female pipe of refrigerant exports 10 and links together by three-way pipe.
