Abstract

The utility model relates to a two-folding evaporator for the separation machine of the air conditioner. Two folding fins are composed of heat exchange pipes and fins. The connecting part of the two folding fins is provided with a notch free position. The utility model aims to solve that the problem that the air flow flows through the short circuit and the air flow does not flow through the fins, and then the heat exchange efficiency is affected. A plastic lining strip is filled in the notch. The both ends of the plastic lining strip are provided with omega-shaped spring clamps which fix the plastic lining strip. The heat exchange efficiency is improved, the operation is simple, the procedure is reduced, and the work efficiency is improved. The utility model is suitable for making simple improvement on the existing two-folding evaporator.

Description

The evaporimeter of separate type air conditioner

The utility model relates to a kind of evaporimeter of air conditioner, particularly a kind of evaporimeter of improved band sealing lead-in.

Roll over two folding junctions of evaporimeters at two of existing air-conditioning split air conditioner, the breach that has certain angle unavoidablely, the breach at 65 ° of angles for example, neutral gear makes and easily walks short circuit by the air intake of flase floor herein, part air intake short circuit process indentation, there, and without heat-exchange fin, reduced the cooling and warming ability of device, therefore need to improve this evaporimeter, set up some parts and walk problem of short-circuit, improve heat-exchange capacity to solve air intake.

The purpose of this utility model is to avoid weak point of the prior art and provides a kind of and can eliminate the simple and easy modifying device that the air-flow short circuit phenomenon improves the evaporimeter heat-exchange capacity.

The purpose of this utility model can reach by following measure:

Imbed the rubber or the plastics lead-in of a strip at the continuous neutral place, position of two foldings of air-conditioning split air conditioner two folding evaporimeters, all clog at the place with neutral gear, fixes it then.Fixing means can screw on the cross recess tapping screw at the lead-in two ends, in this way because left and right sides side plate is equipped with U-shaped pipe and semicircle pipe, as operate bad long U pipe of meeting clashing and breaking and semicircle pipe with nail device on the semi-automatic wind-force screw, with the manual operations of cross recess screwdriver, work efficiency is very low.Another kind method is to use custom-designed Spring Card, insert from the slit between two fins with this kind Spring Card at the lead-in two ends, lead-in is pressed abd fixed on breach neutral gear place, thereby avoids air intake to pass through, and reach the purpose that improves refrigeration, heating capacity from the indentation, there short circuit.

The Spring Card that is used for fastening lead-in is to be made by stainless steel wire, and a split circlip of approximate Ω shape has used it, just can cancel the operation with the screwdriver screwing, has improved work efficiency, has guaranteed the product quality of evaporimeter.

The utility model evaporimeter has following advantage:

1, avoids the air intake short circuit, improved heat exchanger effectiveness.

The utility model stops air intake to pass two folding breach neutral places, thereby improves heat exchanger effectiveness and refrigerating capacity owing to be provided with the lead-in that keeps out the wind.

2, operation is simple and easy, reduces operation, improves work efficiency.

The utility model adopts Spring Card to replace the screwing operation, and for this two folding evaporimeters because its structural relation, herein screwing can only be to use screwdriver manual operations, can not use semi-automatic operation tool, therefore must be manual operations, the work that work efficiency is low.The utility model all is easy on the structure and on the manufacturing process when improving heat exchanger effectiveness, does not need to improve with the cost that increases cost the quality of product.

Description of drawings: Fig. 1 is the front view of the utility model evaporimeter, and Fig. 2 is its side view, and Fig. 3 is the A-A cutaway view, and Fig. 4 is the front view of Spring Card (5,5 ＇).Among each figure: the 1, the 3rd, right side plate, the 4, the 6th, left side plate, the 2nd, tapping screw, 5,5 ＇ are Spring Cards, the 7th, lead-in, the 8, the 10th, fin, the 9, the 11st, long U pipe, the 12nd, semicircle pipe.

Embodiment: in the two-fold evaporimeter of an air-conditioner, this evaporimeter comprises several rows of long U-shaped pipe (9,11), connect into heat-exchange tube with some semicircle pipes (12), numerous thermofins are set between these pipes, as shown in drawings, fins set is divided into two foldings, i.e. fin (8) and fin (10), with right side plate (1,3) and left side plate (4,6) whole evaporimeter is assembled, intersected 65 ° of angles between two foldings.The junction forms a rectangular breach, the lead-in (7) that rubber or plastics are made in the filling of this indentation, there, be fixed with tapping screw at the lead-in two ends, the Spring Card (5,5 ＇) of perhaps using Ω shape compresses lead-in to fix it from the slit between the position insertion fin at lead-in two ends.This spring leaf can be made as shown in Figure 4 Ω shape with the stainless steel wire of φ 1m/m.Like this, just, constitute the utility model evaporimeter.

Claims

1, a kind of two folding evaporimeters are by long U-shaped pipe (9,11), semicircle pipe (12), two folding fins (8 and 10), right side plate (1,3) and left side plate compositions such as (4,6) is characterized in that, at two folding fins (8) and the crossing formed indentation, there filling of fin (10) lead-in (7) are arranged.

2, evaporimeter according to claim 1 is characterized in that, has two Spring Cards (5,5 ＇) to insert space between fin with fixing lead-in at place, the two ends of lead-in (7).

3,2 described evaporimeters as requested is characterized in that Spring Card (5,5 ＇) is the Ω shape split circlip made from steel wire.
