Crushing and Separating Device for Core for Heat Exchanger {CRUSHER AND SEPARATING OF HEAT EXCHANGER}

The present invention relates to a device for crushing and separating waste cores for heat exchangers, and more specifically, for heat exchangers for automatically squeezing, cutting, crushing, and discharging fins and tubes of cores that have been disassembled in a heat exchanger at the end of service life. It relates to a shredding and separating device of the core.

Generally, a heat exchanger is a device that transfers heat from a high temperature fluid to a low temperature fluid through a heat transfer wall, and a heat exchanger is typically a radiator, an evaporator, or a condenser according to a purpose of use. Used as a condenser, a radiator in the heat exchanger is a device that emits a part of the heat generated from the internal combustion engine to the atmosphere through the cooling water, and an evaporator is a heat source in the surroundings when the liquid evaporates and becomes a gas. It is a device that absorbs water and rapidly lowers the surrounding temperature. It is mainly used in refrigerators such as refrigerators. Condenser is also one of the engines found in refrigerators and air conditioners. By changing to a liquid refrigerant, such a heat exchanger exchanges heat by circulating a heat transfer medium inside the tube. Device.

Meanwhile, cores, which are the core parts of the heat exchanger, are divided according to their types.

First, the honeycomb fin type in which the tubes are arranged in a zigzag and a hexagonal cooling fin is installed between the tubes.

A plate pin type that fits the tube into a number of thin plates drilled into the tube,

There is a type of corgate pin that zigzags thin cooling fins between the tubes between the two plates.

As shown in FIG. 1, the core of the plate pin type has a through hole 4 formed in a plurality of thin plate-like pins 2 made of aluminum or copper alloy, as shown in FIG. 1.
