INTEGRAL HEAT EXCHANGER PLATE AND INTEGRAL HEAT EXCHANGER THEREWITH

摘要

PURPOSE: An integral heat exchanger is provided to obtain compact structure of air conditioner by integrating inlet and discharge ports for refrigerant and cooling water to a single plate including an evaporator and a heater core and to cut down costs by simplifying components. CONSTITUTION: A plate(5) is divided into an L-shaped evaporator plate(6) and a rectangular heater core plate(7) by a first L-shaped partition rib(51). A first and a second hole cup(61,62) are formed parallel at the lower end of the evaporator plate. An L-turn path(63) is formed on the evaporator plate by a second L-shaped partition rib(52) formed to the bent upper end from a clearance between the first and the second hole cup. A third and a fourth hole cup(73,74) are formed parallel at the lower end of the heater core plate. A U-turn path(75) is formed on the heater core plate by a third partition rib(53) extended to the bent upper end from a clearance between the third and the fourth hole cup. The plate is formed integrally, including an evaporator and a heater core. In addition, plural inlet and outlet ports for refrigerant and cooling water are formed integrally on the single plate. Therefore, components are simplified and costs are cut down.
