Fig. 2 is the partial schematic diagram at the A position of the heat-exchanging water tank shown in Fig. 1.
Detailed description of the invention
Fig. 1 is the schematic diagram of the heat-exchanging water tank for Teat pump boiler of the utility model embodiment, and Fig. 2 is the partial schematic diagram at the A position of the heat-exchanging water tank shown in Fig. 1.As depicted in figs. 1 and 2, heat-exchanging water tank 100 for Teat pump boiler comprises inner bag 110 for holding water and micro-channel heat exchanger, micro-channel heat exchanger comprises two headers 120 and multiple flat heat exchange pipe 130, two headers 120 are arranged along the outer wall interval of inner bag 110, multiple flat heat exchange pipe 130 is connected between two headers 120 at each interval, and the two ends of each flat heat exchange pipe 130 are communicated in two headers 120 respectively, multiple flat heat exchange pipe 130 are attached at the outer wall of inner bag 110.After refrigerant after compressor compression enters a header, flow to another header through multiple flat heat exchange pipe 130, then flow to throttling arrangement by another header, flow to evaporimeter from throttling arrangement afterwards, finally get back to compressor and form closed circuit.In the process, when header 120 and flat heat exchange pipe 130 have refrigerant to flow through, heat exchange will be carried out with inner bag 110, thus the temperature of the water in inner bag 110 is raised, reach the object preparing hot water.
In order to promote the heat exchange efficiency between header 120 and inner bag 110, the utility model embodiment makes the partial outer face of header 120 be attached at the outer wall of inner bag 110 especially, to contact with the outer wall forming surface of inner bag 110, usually the circular header adopted compared to existing technology, contact area greatly increases, and heat exchange efficiency significantly improves.
In certain embodiments, the outer wall profile of inner bag 110 can be cylindric, and the central axis that two headers 120 now can be made all to be parallel to inner bag 110 is arranged, and multiple flat heat exchange pipe 130 is along the outer wall circumference interval setting of inner bag 110.More fully covered by flat heat exchange pipe 130 to make inner bag 110 outer wall, to accelerate heat transfer rate, the angle (the angle α with reference to figure 1) that the central axis of two headers 120 and inner bag 110 is formed can be less than predetermined angle (being preferably less than 30 °), and multiple flat heat exchange pipe 130 is arranged along the outer wall circumference of inner bag 110 respectively, and is connected to two headers 120 with longer camber line between two headers 120.
When inner bag 110 outer wall profile is cylindric, in order to make header 120 outer surface contact with inner bag 110 outer wall forming surface, the part surface that header 120 can be made to be attached at the outer wall of inner bag 110 is the cambered surface with inner bag 110 outer wall mating shapes.For ease of processing, the one side of the opposing outer wall in inner bag 110 of header 120 can be semicircle cambered surface (with reference to figure 2).Certainly, if when the external diameter of inner bag 110 is enough large, for ease of processing, the part surface of the outer wall being attached at inner bag 110 also can be made to be plane, header 120 also can be made fully to contact with the outer wall of inner bag 110.
In addition, flat heat exchange pipe 130 can be close to the surface of the header 120 of the outer wall being attached at inner bag 110 with the tie point of header 120, to make the end of flat heat exchange pipe 130 more close to the outer wall of inner bag 110, make flat heat exchange pipe 130 be attached to the outer wall of inner bag 110 more, strengthen heat transfer effect between the two.
The utility model embodiment still provides a kind of Teat pump boiler, and this Teat pump boiler applies the heat-exchanging water tank 100 of aforementioned any one.Known by describing above, the outer wall of this heat-exchanging water tank 100 because making the partial outer face of header 120 be attached at inner bag 110, thus contact with the outer wall forming surface of inner bag 110, usually the circular header adopted compared to existing technology, contact area greatly increases, heat exchange efficiency significantly improves, and the efficiency of Teat pump boiler is highly improved.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is described herein detailed, but when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
