PLATE HEAT EXCHANGER

摘要

PURPOSE: A plate-shaped heat exchanger is provided to improve heat exchanging efficiency by heat-exchanging homogeneous state of gas and liquid in a second channel forming groove portion. CONSTITUTION: A plate-shaped heat exchanger comprises a heat exchanging plate(300), a first channel forming groove portion(310a), a mixing groove portion(320), and a second channel forming groove portion(310b). The first channel forming groove portion is formed for heat exchanging between fluids. The mixing groove portion is installed in the rear portion of the first channel forming groove portion for the mixing of the fluids passing through the first channel forming groove portion. The second channel forming groove portion is installed for heat exchanging between fluids passing through laminated heat exchanging plates.
