Expansion pipe and pressure resistance sealing detection device of surface air cooler

Abstract

The invention discloses an expansion pipe and pressure resistance sealing detection device of a surface air cooler. The device comprises a hydraulic device body and a surface air cooler body. The hydraulic device body is provided with an input pressure gauge, an operation indication lamp, an expansion pipe start button, and a pressure-resistant start button, and a lower part of the hydraulic device body is provided with a water tank; an output pressure gauge and a strong joint gauge rod are arranged at a water outlet end of the water tank; the surface air cooler body comprises a copper pipe, radiating fins and end plates on two sides; a quick connector is mounted on each end plate, and an exhaust valve is mounted on the quick connector; and each end plate is further provided with a quick clutch, the quick clutch is connected with an output end of a high-pressure hose, and an input end of the high-pressure hose is connected with the strong joint gauge rod. Under a condition that the structure of the surface air cooler is not damaged, a diameter of the copper pipe can be expanded reliably and effectively, fins on the copper pipe of the surface air cooler are tightly combined with a pipe wall of the copper pipe, and heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an expansion tube of a surface cooler and a pressure-resistant seal detection device. Background technique [0002] In the current refrigeration industry, the copper tubes of surface coolers generally use TP2 high-quality red copper tubes, and the cooling fins and copper tubes are subjected to expansion and permanent pressure maintenance and leak detection operations to ensure that the two are tightly combined without leakage , can greatly enhance the heat conduction effect. At present, the air pressure tube expansion operation and leak detection operation of copper tubes and cooling fins in the industry is to continuously apply high air pressure to the copper tube during the tube expansion process, so that the copper tube expands slowly. Because the high-pressure gas is applied, even if the pressure value required by the process is applied every time, the phenomenon of...
