Abstract

The utility model provides a water air-conditioning heat exchanger, which changes a common end cover into a shunt sealing end cover based on the existing heat exchanger. The utility model utilizes a water-retaining shunting plate, a rubber sealing plate, an end surface fastening plate and a water flow end cover which are engaged with each other, which not only replaces a U-type metal elbow, but also enables the heat exchanger to achieve integral non-welding effect, thereby eliminating the trouble of welding. Further, the water air-conditioning heat exchanger can be made of non-metal materials such as nylon or plastics, and can save a plurality of metal materials. The water air-conditioning heat exchanger has the advantages of simple structure, convenient assembly, no need of welding and low manufacturing cost, and is mainly suitable for a cold-hot water air-conditioning heat exchange system or a mechanical water-cooling system.

The specific embodiment

Accompanying drawing is to be example with U type tubular type and calandria respectively, non-limitingly discloses two specific embodiments of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.

Accompanying drawing 1 is the structural representation of U type pipe heat exchanger, and because of heat exchanger tube is a U type pipe, so only need mouth of pipe place at one end to use shelves water flow distribution plate to replace U type metal bends to get final product, 1 among the figure is U type pipe; The 2nd, fin; The 3rd, end face snapping plate; The 4th, whole rubber gasket sheet; The 5th, the dash flow distribution plate on the sink cover; The 6th, the Inlet and outlet water interface; The automatic drainage interface of 7 pressure; The 8th, the end cap of leaking water.This figure combines to the example description with some U type pipes, for the heat exchangers of different sizes, and the design as long as the suitable quantity that increases and decreases pipe all can use the same method.Be distributed with the comb hole 10 of stretching on the described end face snapping plate 3 (referring to Fig. 2), be provided with button limit 11 around the end face snapping plate, be provided with whole rubber ring 12 with the rubber gasket sheet 4 (referring to Fig. 5) of stretchable holes 10 correspondence positions of end face snapping, the end cap 8 (referring to Fig. 8) of leaking water is provided with Inlet and outlet water interface 6 and the automatic drainage interface 7 of pressure.Described rubber gasket sheet 4 is withheld on end face snapping plate 3 through rubber ring 12 and comb hole 10, comb 1 is inserted into respectively in the comb hole 10 of end face snapping plate 3 and the sealing ring 12 and through expander and stretchable holes 10 swelling sealing and fixing, the end cap 8 (referring to Fig. 8) of leaking water compresses rubber gasket sheet 4 through snapping limit 11, be fixed on the end face snapping plate 3, dash flow distribution plate 5 retaining is between adjacent U type pipe 1 and clamp and be fixed on rubber gasket sheet 4 and leak water between the end cap 8.The shape of described dash flow distribution plate 5 can be designed to waveform or S shape, V-arrangement, W shape or other shape according to the metal tube arranging situation.Shown among Figure 10 5 is a kind of undaform dash flow distribution plate.Described rubber gasket sheet 4 preferably selects for use the anti-corrosive rubber material to make, and the dash flow distribution plate 5 and the end cap 8 of leaking water can select for use materials such as nylon or plastic cement to make.

Figure 14 is a kind of structural representation of calandria heat exchanger, because of heat exchanger tube is the straight tube of two open ends, so need also use the dash flow distribution plate to replace U type metal bends at the other end, its structure can be on the basis of Fig. 1, the other end at heat exchanger increases by a cover use dash flow distribution plate, rubber gasket sheet, the end face snapping plate and the end cap of leaking water get final product, because of the end cap of setting up does not need to establish the Inlet and outlet water interface again, so the structure of this end cap 9 can be reduced to as shown in figure 12, among the figure 1 is that metal tubes such as " one " font copper tube or aluminum pipe are arranged the comb that forms, other is all identical with Fig. 1, that is: 2 is fins; The 3rd, end face snapping plate; The 4th, whole rubber gasket sheet; The 5th, the dash flow distribution plate on the sink cover; The 6th, the Inlet and outlet water interface; The automatic drainage interface of 7 pressure; 8, the 9th, the end cap of leaking water.This figure combines to the example description with some combs, for the heat exchangers of different sizes, and the design as long as the suitable quantity that increases and decreases pipe all can use the same method.Be distributed with the comb hole 10 of stretching on the described end face fishplate bar 3, be provided with button limit 11 around the end face snapping plate, be provided with whole rubber ring 12 with the rubber gasket sheet 4 of stretchable holes 10 correspondence positions of end face snapping, the end cap 8 of leaking water is provided with Inlet and outlet water interface 6, described rubber gasket sheet 4 is withheld on end face snapping plate 3 through rubber ring 12 and comb hole 10, comb 1 two ends are inserted in the comb hole 10 of two end face snapping plates 3 respectively and in the sealing ring 12 and through expander and stretchable holes 10 swelling sealing and fixing, the end cap 8 of leaking water, 9 compress rubber slab 4 respectively through snapping limit 11, be fixed on the end face snapping plate 3, dash flow distribution plate 5 retaining is between adjacent comb hole 1 and clamp and be fixed on rubber gasket sheet 4 and leak water between end cap 8 or 9.The shape of described dash flow distribution plate 5 can be designed to waveform or S shape, V-arrangement, W shape or other shape according to the metal tube arranging situation.Figure 10 and shown in Figure 14 be a kind of undaform dash flow distribution plate.Described rubber gasket sheet 4 preferably selects for use the anti-corrosive rubber material to make, and the dash flow distribution plate 5 and the

end cap
