Abstract

The utility model relates to a heat exchanger which can be used for recovering waste heat of shower waste water and the occasions such as a constant-temp. occasion, a ventilation occasion, etc. indoors and outdoors. A multi-layer overlapped fluid flow passage with a bow-shaped structure is arranged in the utility model, the fluid which takes part in heat exchanger flows into and out the heat exchanger from the places near the end head parts of both ends on the outside of a groove, and forms multi-layer fluid layers which are mutually alternately overlapped; the heat exchange is carried out efficiently between the adjacent stacks.

Description

A kind of heat exchanger

Described in the utility model is a kind of heat exchanger that can be used for occasions such as shower waste waste heat recovery and the ventilation of indoor and outdoor constant temperature.

Usually, the waste water after the shower is all directly entered sewer, and heat entrained in the shower waste also flows away simultaneously in vain.For with the waste heat recovery in the shower waste, several schemes of patent No. ZL95202934.0 and ZL96200747.1 etc. provide certain solution route, but because all fail to propose succinctly, heat exchanger, thereby practical application is efficiently promoted has certain difficulty.

In addition, the problem of ventilating about indoor and outdoor constant temperature also has multinomial patent to propose solution, same because lack succinctly, efficiently heat exchanger and satisfactory result.

The purpose of this utility model promptly be to provide a kind of succinctly, heat exchanger efficiently.

The purpose of this utility model is to realize like this.

Be provided with the stacked fluid passage of multilayer layer of bow font structure in the heat exchanger, can be by the rectangle sheet material of metal or other thermal conductivity material with punching press or come and go mode such as folding repeatedly and form, this kind structure just forms, anti-two groups of alternately folded grooves also, its bow font folding formed two face C in limit, D is sealing, closed form, stupefied formed two the face A of folding, B is the semi-closed shape, the termination, two ends that is groove is sealing, closed form, the groove outside is open state near the part of termination, two ends, the stage casing part in the groove outside then is provided with closure plate, it is one group of fluid passage that this closure plate should be organized the groove sealing, closure plate with can be also can separating of driving fit between folding is stupefied, but then must be driving fit between the edge outer side edges of the twice groove at the edge of closure plate and this group passage.The open section in two groups of grooves outside can be tightly connected by connecting pipe etc., after participating in positive and negative two groups of passages of two kinds of fluids by difference reverse flow over-heat-exchangers such as connecting pipes of heat exchange, just can form alternately folded mutually multi-layered fluid layer also, and between adjacent laminates, carry out heat exchange expeditiously.

Below in conjunction with Fig. 1 to Fig. 6 most preferred embodiment of the present utility model is described once.As shown in Figure 1, rectangular metal plate is processed into a carefully and neatly done stacked structure of bow font multilayer layer, and its overall profile can be coincide with a regular hexahedron, as shown in Figure 2.Among Fig. 2, end face A and bottom surface B represent stupefied formed two faces of folding respectively, and C and D then represent respectively by formed two faces in bow font folding limit.With C, D two sides seal respectively, closure, A, B two sides just form one group of stacked groove arranged side by side respectively, and two groups of grooves are alternately folded mutually also, as shown in Figure 3, again the semi-closed shape is processed on A, B two sides respectively, the place, two ends that is the groove outside is open state, and the stage casing part is closed form, as shown in Figure 4.Fig. 5 is the schematic diagram that one of fluid of participation heat exchange flows through one group of passage of heat exchanger, and Fig. 6 then flows through the schematic diagram of another group passage of heat exchanger for the opposing party's fluid that participates in heat exchange.Its using method is, when being used for shower waste waste heat recovery occasion, this heat exchanger is placed the bottom of shower house, fresh water injects heat exchanger and discharges heat exchanger from other end open ports of this group groove from an end open ports of one group of groove of A or B face via interface channel, flows to shower via interface channel etc. again; Shower waste another end open ports of organizing the contiguous fresh water water outlet of groove from heat exchanger after shower house is collected is injected heat exchanger, and discharges from an end open ports of contiguous fresh water entry.Heat exchanger is divided into alternately folded mutually current layer also respectively with shower waste and fresh water, because heat exchange mainly is to carry out between each adjacent current lamination, heat exchange area is big, thereby the heat exchange efficiency height.Heat exchanger with this kind structure is the formed excess heat recovery device for shower waste water of core, can reclaim the most of heat in the shower waste, saves a large amount of energy.Equally, when being used for indoor and outdoor constant temperature ventilation occasion, the indoor and outdoor air is with above-mentioned similar method heat-shift in heat exchanger, thereby realization constant temperature ventilates.

Experimental result shows, the heat exchanger that the utility model proposed, and the recess width in the stacked structure of its bow font multilayer layer should be to be advisable less than 1.5mm.
