Detailed description of the invention
As shown in Figure 3, heat exchanger backplate 2 arranges punching, heat exchanger tube 4 passes from punching, nested retaining ring 3 in punching.In embodiment, heat exchanger backplate 2 still adopts steel plate, and heat exchanger tube adopts copper pipe.The material of retaining ring 3 can select copper, aluminium that hardness is lower, or stainless steel, make retaining ring material hardness lower than heat exchanger side plate material hardness, during heat exchanger poling, heat exchanger tube 4 is passed from retaining ring 3, carry out expand tube work again and install copper elbow 1, after heat exchanger tube 4 expand tube, outer wall and described retaining ring 3 inwall are fitted.
Copper retaining ring is selected to be described to retaining ring in embodiment 3 below.Add between the punching and heat exchanger tube 4 of heat exchanger backplate 2 after joining copper retaining ring, the phenomenon causing heat exchanger tube to break because of friction can be effectively reduced; Because copper retaining ring is identical with the material of heat exchanger tube 4; copper material is relatively soft, and in addition, copper retaining ring joins work according to the caliber of heat exchanger tube 4; after expand tube; copper retaining ring and heat exchanger tube 4 are fitted closely, relatively form one, avoid heat exchanger tube 4 and directly contact with 2 of heat exchanger backplate; under the effects such as heat exchanger vibration; copper retaining ring and heat exchanger backplate 2 rub, and effectively protect heat exchanger tube 4, thus eliminate heat exchanger tube 4 because of the heat exchanger backplate punching limit higher with material hardness and to rub the problem producing and break.Simultaneously because retaining ring material is softer, certain deflection can be held when heat exchanger tube expands with heat and contract with cold, also avoid breaking of heat exchanger tube to a certain extent.
In order to realize the technical solution of the utility model, specifically provide following embodiment.
