Abstract

The utility model relates to a film laminated type heat medium exchanging apparatus. A heat-exchange surface is a flexible thin film; a B-shaped convex shuttle is arranged on one end surface, and two mutually staggered layers of fences are arranged in the convex shuttle. Holes for inserting supports bar are distributed on both the upper and the lower edges of the end surface, and the support bars are inserted between an upper and a lower end surfaces. The flexible thin film which is folded in order is wound between the support bars and is adhered on the fences of an end cover. The heat medium exchanging apparatus has the advantages of large heat exchanging area, simple structure and low cost, and can be assembled into large and medium heat medium exchanging apparatus as needed.

Description

Laminated type heat-exchange media apparatus

The utility model belongs to a kind of heat and mass exchanger.

Existing heat and mass exchanger mainly contains rib-type, positive displacement, board-like, tubular type and heat pipe-type etc.It is made material and mostly is metal or other rigid material, complex manufacturing technology, and the cost height, every square metre of heat exchange area cost does not wait to units up to ten thousand from hundreds of.From the efficient of unit volume heat-exchange apparatus, except that board-like, heat pipe-type reach the very accurate ribbing tubular type, all the other are all as one wishes not to the utmost.Therefore, extremely unbecoming economically when existing heat (matter) interchanger is used for caloic exchange between low pressure reduction, little temperature difference fluids working medium, make that many waste heats and used heat can't utilize in life and the production process.

The purpose of this utility model is to provide a kind of caloic exchange efficiency height, makes simple, the low range of application heat and mass exchanger more widely that reaches of cost.

Folded membrane type heat and mass exchanger of the present utility model, mainly form by shell, heat-insulation layer, support member and caloic exchange face, it is characterized in that: caloic exchange face is a fexible film, a day font fin is arranged on the end face, be provided with interlaced two-layer barrier in the fin, the bottom and upper segment of end face is evenly equipped with the hole of assigning support bar, and support bar assigns between the upper and lower end face, fexible film folds, is wrapped between the support bar along continuous, and is bonded on the barrier on the end cap.

Fexible film can be plastic sheeting, paper, metal film, chemical fabric.

Two-layer barrier can be vertical interlaced setting or tilting one-tenth broken line＜shape.

The utility model has the advantages that the caloic exchange area in the unit volume is big, the efficient height; Unit caloic exchange area is cheap, and the conservation measures that is not collectively referred to as economically and can't realizes of making over becomes possibility.The utility model simple structure is made handling ease, is fit to carry out continuous productive process production.Be designed to the standard monomer, be combined into large and medium-sized heat-mass exchange equipment then as required.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is an embodiment external form front view (partial cutaway).

Fig. 2 is I-I profile of Fig. 1.

Fig. 3 is II-II profile of Fig. 1.

Fig. 4 is the utility model caloic exchange principle schematic diagram.

As shown in the figure: the caloic exchange face of folded membrane type heat and mass exchanger is a fexible film 4, a day font fin is arranged on the end face 1,2, be provided with interlaced two-layer barrier 7 in the fin, the bottom and upper segment of end face 1,2 is evenly equipped with the hole of assigning support bar 3, support bar 7 assigns between upper and lower end face 1 and 2, fexible film 4 folds, is wrapped between the support bar 3 along continuous, and is bonded on the barrier 7 on the end cap 1,2.Two-layer barrier 7 can be vertical interlaced setting or tilting one-tenth broken line＜shape, the equal diameters of the width of barrier 7 and support bar 3, and the barrier 7, support bar 3 and the film 4 bonding formation compartments make the working medium L on film 4 both sides ₁, L ₂Shunting.The working medium on film 4 both sides is carried out reverse caloic exchange by film 4 in the process of circulation.The spacing of film 4 can be in 5mm, thereby the heat-exchange surface in the unit volume is more much bigger than traditional heat and mass exchanger.

Select for use different films can satisfy different caloic switching purposes.As when selecting perforated membrane for use, be full heat exchange; When selecting non-porous film for use, be the sensible heat exchange.

End face 1,2, support bar 3, constitute kernel of the present utility model with film 4, add heat-insulation layer 6 and shell 5 after, promptly finish its whole formations.
