Description

Assembling type air heat exchanger

The present invention relates to a kind of air heat exchanger, belong to apparatus of air conditioning technical field.

The patent ZL95239140.6 of the People's Republic of China (PRC) discloses a kind of liquid circulation cooling and warm air-conditioner, is the cooling and warm medium with normal pressure liquid wherein; In addition, fan coil system (a kind of central air conditioner system), if refrigerant during horizontal layout wherein also is a normal pressure, when solid was arranged, the refrigerant in the top layer fan coil also was a normal pressure; Also having a kind of is the air-conditioning system of cold-producing medium with underground water, when its horizontal layout, or the top layer during three-dimensional the layout, water wherein also is normal pressure.If air-conditioner or air-conditioning system that the nontoxic no corrosive liquid of above normal pressure is a refrigerant still with the sort of air heat exchanger that is used for high-pressure refrigerant, so, can increase material, processing and equipment cost because of too high sealing.The air heat exchanger that is used for high-pressure refrigerant for guaranteeing air-tightness, needs with the copper pipe that is installed with fin in a large number, and to so that copper pipe closely contacts with fin, also copper pipe to be welded at last the whole expander of copper pipe, and welding process requirement is high, so cost is very big.

The purpose of this invention is to provide the assembling type air heat exchanger that a kind of connector connects, it can reduce manufacturing cost.

The object of the present invention is achieved like this: by the assembling type air heat exchanger that mental-finned gathers into folds and constitutes, its characteristics are that what be positioned at two ends is the end assembly, and there is the multi-disc fin that gathers into folds the centre; A logical liquid short tube perpendicular to the fin face that position on each fin is identical is at least respectively arranged on all fins; The identical logical liquid short tube alignment in the position of on all fins all on each fin gathers into folds and connects into separately stacked pipe; All stacked pipes are interconnected the whole stream that forms air heat exchanger by the connecting line in the assembly of end; The end assembly is by the assembling of overall connector, clamps therebetween all stacked pipes to fix all fins in the middle of it.

The structure of the logical liquid short tube on the fin can be one of following form: (1) directly is processed into tubular hole by the hole on the fin, and there is the sealing surface that is fit to sealing at two ends, and at its end away from the fin face one section contraction section is arranged; (2) be processed into tubular hole and put sleeve pipe outside tubular hole by the hole on the fin, there is the sealing surface that is fit to sealing at two ends, and at its end away from the fin face one section contraction section are arranged; (3) pressing one little short tube in the hole on the fin, two ends have the sealing surface that is fit to sealing; (4) comprise that above-mentioned form is combined in other interior suitable structures.

With the alignment of the logical liquid short tube on each fin connected mode that connects into stacked pipe separately that gathers into folds is one of following manner: (1) all adjacent logical liquid short tubes that all positions on each fin on all fins are identical directly contact connection; (2) the pad pad of the attached adhesive of single face connects after between all identical adjacent logical liquid short tube end faces of the position on each fin on all fins all again; (3) the pad pad of two-sided attached adhesive connects after between all identical adjacent logical liquid short tube end faces of the position on each fin on all fins all again; (4) on all fins all are bonded together behind the identical attached adhesive of all adjacent logical liquid short tube end faces in the position on each fin; (5) comprise that aforesaid way is combined in other interior applicable pattern.

The structure of the end face that the connecting line in the assembly of end contacts with stacked pipe can be one of following form: the position that all interior connecting lines of the end assembly of (1) one end contact with stacked pipe end face at grade, connecting line is a sealing surface with the position that stacked pipe end face contacts; Connecting line in the end assembly of the other end has the pipeline section of the adjustable extension elongation of dock with each stacked pipe, in order to holding out against the stacked pipe that docks separately respectively, the pipeline section of adjustable extension elongation what contact with stacked pipe end face is sealing surface to inner end; (2) connecting line in the end assembly at two ends all has the pipeline section of the adjustable extension elongation of dock with each stacked pipe, in order to holding out against the stacked pipe that docks separately respectively, the pipeline section of adjustable extension elongation what contact with stacked pipe end face is sealing surface to inner end; (3) position that contacts with stacked pipe end face of all connecting lines in the end assembly at two ends at grade, connecting line is a sealing surface with the position that stacked pipe end face contacts; (4) comprise that aforesaid way is combined in interior alternate manner.

Anti-fin can be one of following form along auxiliary the fixing that its fin face direction moves: (1) all fins rely on overall connector auxiliary fixing; (2) the some fins in interval have the auxiliary fixedly auxiliary fixing member of fin effect with regard to folding in the fin that gathers into folds; (3) comprise that above-mentioned form is combined in other interior form.

Assembling type air heat exchanger of the present invention, though many logical liquid short tubes on the fin, logical liquid short tube and fin can be processed simultaneously, thereby the increase of fin cost is very little or do not increase; Just because of logical liquid short tube is arranged on the fin, so poling has more not only reduced material consumption, also cancelled the operation of the whole expander of copper pipe (or aluminum pipe), owing to adopting connector, assembles by heat exchanger again, thus need not welding sequence, thereby cost has tangible reduction in general; In addition, because fin directly contacts with liquid medium, so heat transfer property is fine.

The invention will be further described below in conjunction with drawings and Examples:
