Abstract

A device used for measuring vertical intensity of corrugated fin plate on heat exchanger under horizontal-loading is prepared as fixing piezoelectric transducer of 3-phase dynamic meter on operation table of digital controlled miller, connecting said transducer to charge amplifier and computer with A / D collection card through signal line, fixing mould on mould fixing table being fixed on platform of said transducer, fastening test-piece fixing case on cutter handle of 3-shaft digital controlled miller and locking rotary freedom of cutter handle on 3-shaft digital controlled miller.

Description

technical field [0001] The invention relates to a measuring device in the technical field of refrigeration engineering, in particular to a measuring device for vertical strength of corrugated fins of a heat exchanger under lateral loading. Background technique [0002] As a compact heat exchanger, the tube-fin heat exchanger has a wide range of applications in the air-conditioning and refrigeration industries. With the technical development of the air conditioning and refrigeration industry and the further strict control of environmental regulations, improving the heat transfer coefficient of the heat exchange unit itself is a necessary means to improve the overall heat transfer performance of the heat exchanger and compensate for the low performance of alternative refrigerants. The air conditioner heat exchanger (including the indoor unit condenser and the outdoor unit evaporator) needs to be bent as a whole after the piercing and expansion process. In the traditional heat...
