Abstract

The invention discloses a manufacture method of an exposed heat exchanging device. Cheap cylindrical plastic films or rain-proof silk fabrics are used for manufacturing a heat exchanging material, a frame or a plastic mesh is utilized to fix the cylindrical plastic film into a single-layer piece-shaped heat exchanging structure, then the single-layer piece-shaped heat exchanging structure and the other frame are used for fixing the other cylindrical plastic film into a piece-shaped heat exchanging structure. By parity of reasoning, a multiple-layer structure that every two layers of structures wrap a layer of cylindrical plastic films is formed, then the cylindrical plastic films at the same end are collected to the same position, one end serves as a water inlet, one end serves as a water outlet, and a heat exchanging medium can perform heat exchange inside and outside the plastic films. The manufacture method is mainly used for heat exchange of mariculture enterprises so as to reduce the procurement cost of heat exchanging devices of the enterprises, promote waste heat recovery and popularize heat exchange technologies and other energy-saving technologies in the mariculture industry.

Description

A kind of preparation method of bareing heat-exchanger rig

One, technical field

The invention belongs to the heat transmission equipment manufacture technology field, relate in particular to a kind of preparation method of the heat-exchanger rig that is applicable to seawater of cheapness.

Two, background technology

at present, on all markets in existing heat exchanger kind, distinguish by making material, be applicable to the stainless steel material that mainly contains of seawater, titanium material and plastic material heat exchanger etc., these heat exchange products have a general character, be that cost is higher, the cost of every square metre is all at least more than 100 yuan, many reaches more than 1000 yuan, high cost has limited its large tracts of land in some field and has used, universal, such as: in the sea-farming industry, facts have proved, relatively applicable heat exchanger product is the titanium plate type heat exchanger, but this kind heat exchanger cost is high, every square metre more than 1000 yuan, so, although effect is remarkable, 50% left and right of can economizing on coal, but use the sea-farming enterprise of titanium heat exchanger still only for large-scale strong enterprise, be difficult to comprehensively universal, and due to its high cost, also limited simultaneously its usable floor area, cause the energy-saving efficiency of most of enterprise low, generally all below 50%.Also have Some Enterprises to adopt stainless heat exchanger, although cost is slightly low, every square metre of 400 yuan of left and right, the stainless steel corrosion resistance is poor, causes the life-span short, only has about 4 years.In the case, high for overcoming the heat exchanger or the cost that have now in the use of aquaculture industry, or the life-span is short, be difficult in the comprehensive universal shortcoming of sea-farming industry, Patent design of the present invention a kind of novel bareing heat-exchanger rig of making the heat exchange material of plastic sheeting, its characteristics are to use cheap cylinder type plastic sheeting or rain repellent silk etc. to do the heat exchange material, utilize framework or plastic wire that the cylinder type plastic sheeting is fixed into the sheet heat exchange structure, by and the mode that connects make heat-exchanger rig.Implementation during its concrete heat exchange is as follows, and this device is soaked in heat transferring medium, and in plastic sheeting, by another part heat transferring medium, these two parts of media just can be realized heat exchange.Owing to adopting plastic sheeting to do the heat exchange material, so the cost of this heat exchanger is extremely low, every square metre 20 yuan of left and right, have overcome the high shortcoming of heat exchanger cost of present use fully, make the sea-farming industry comprehensively universal heat recovery technology become possibility.

Three, summary of the invention

The object of the invention is to improve the deficiency of prior art, provide the existing heat exchanger price of overcoming of a kind of new cheapness high or seawater corrosion resistance not, thereby limit it in the preparation method of a kind of heat-exchanger rig of the difficult problems such as sea-farming industry large tracts of land is universal.

the object of the present invention is achieved like this, use cheap cylinder type plastic sheeting or rain repellent silk etc. to do the heat exchange material, utilize framework or plastic wire that the cylinder type plastic sheeting is fixed into individual layer sheet heat exchange structure, with individual layer heat exchange structure and another framework, other a cylinder type plastic sheeting is fixed into the sheet heat exchange structure again, by that analogy, form the sandwich construction that every two-layer framework must wrap up one deck cylinder type plastic sheeting, and then the cylinder type plastic sheeting of same end is gathered merge a place, one end is done water inlet, one end is done delivery port, heat transferring medium can carry out the preparation method of a kind of heat-exchanger rig of heat exchange inside and outside plastic sheeting.

compared with the prior art the present invention has following distinguishing feature and good effect: the present invention uses cheap cylinder type plastic sheeting or rain repellent silk etc. to do the heat exchange material, cheap, utilize framework or plastic wire that the cylinder type plastic sheeting is fixed into the sheet heat exchange structure, form the sandwich construction that every two-layer framework must wrap up one deck cylinder type plastic sheeting, and then the cylinder type plastic sheeting of same end is gathered merge a place, one end is done water inlet, one end is done delivery port, heat transferring medium can carry out the preparation method of a kind of heat-exchanger rig of heat exchange inside and outside plastic sheeting, manufacture craft is simple, every square metre of overall cost is 20 yuan of left and right, / 10th of the not enough titanium that uses at present or a stainless heat exchanger.Patent of the present invention has overcome following several the shortcomings of existing heat-exchanger rig: 1, cost is high, seawater has very strong corrosivity, the heat exchanger that uses in seawater is generally used the titanium material, every construction cost per square meter is not less than 1000 yuan, even stainless steel also is not less than 400 yuan, and the heat-exchanger rig cost of patent of the present invention is every square metre of 20 yuan of left and right; 2, corrosive properly is strong, and this heat-exchanger rig can all adopt plastics or glass-reinforced plastic material structure, and corrosion resistance is strong, the plastic sheeting replaceable, and the life-span is more than 20 years; 3, due to cheap, for sea-farming enterprise, this heat-exchanger rig usable floor area does not within the specific limits have restriction substantially, thereby has effectively improved heat exchange efficiency, has increased the possibility of comprehensively popularizing.

Four, specific embodiments

embodiment 1, a kind of preparation method of bareing heat-exchanger rig, the present invention uses cheap cylinder type plastic sheeting or rain repellent silk etc. to do the heat exchange material, utilize framework or plastic wire that the cylinder type plastic sheeting is fixed into individual layer sheet heat exchange structure, with individual layer heat exchange structure and another framework, other a cylinder type plastic sheeting is fixed into the sheet heat exchange structure again, by that analogy, form the sandwich construction that every two-layer framework must wrap up one deck cylinder type plastic sheeting, and then the cylinder type plastic sheeting of same end is gathered merge a place, one end is done water inlet, one end is done delivery port, heat transferring medium can carry out heat exchange inside and outside plastic sheeting.

Claims

1. the preparation method of a bareing heat-exchanger rig, it is sandwich construction, its individual layer heat exchange structure is fixed into sheet by framework or plastic wire with the cylinder type plastic sheeting and realizes.
