Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid half-welded primary surface heat exchanger

The present invention relates to a hybrid semi-welding type main heat-generating surface heat exchanger. More particularly, the present invention relates to a hybrid type air conditioner having a distribution channel between stacked heat exchange plates to facilitate the flow and dispersion of the fluid, and to attach a heat exchange plate to the rim of the main heat transfer surface by laser welding, thereby maximizing the heat exchange area, The present invention relates to a semi-welded heat exchanger.

Generally, a heat exchanger is used in various fields as a device for transferring heat from a high temperature fluid to a low temperature fluid to increase the energy of the low temperature fluid and to audit the energy of the high temperature fluid. For example, it is used in power plants, gas turbines, heating devices, air conditioners, refrigeration equipment, chemical industry and so on.

The conventional tubular heat exchanger is generally configured to transmit heat through a tube through which the heating medium flows and through heat conductive fins formed in the tube to increase thermal efficiency. Such a tubular heat exchanger has a problem that the heat transfer area (m 2 / m 3) to volume is low, so that it is difficult to miniaturize and the application field is limited.

The conventional fin-plate type heat exchanger is generally constructed by stacking a plurality of primary surface plates. Further, a plurality of fins are welded vertically on the surface of the plate on the main surface, or a corrugated plate is provided between the heat exchange plate and the plate to form a secondary surface.

For example, Korean Unexamined Patent Publication No. 1992-16807 discloses a flat plate type heat exchanger in which a plurality of gas heat transfer plates and a plurality of air heat transfer plates are aligned with each other at an angle of 90 degrees and mounted in a rectangular frame to recover waste heat. Such a plate-type heat exchanger has a problem that the heat transfer area (m 2 / m 3) in relation to the volume is low and must be made larger in order to obtain the required thermal efficiency.

Therefore, a solution to this problem is required.
