Abstract: The evaporator unit includes an ejector, a discharge-side evaporator, and a suction-side evaporator. The discharge-side evaporator includes discharge-side tubes and a discharge-side tank. The discharge-side tank defines a discharge-side distribution chamber therein which distributes refrigerant to the discharge-side tubes. A partition plate is disposed in the discharge-side distribution chamber and divides the discharge-side distribution chamber into an ejector-side distribution chamber and a tube-side distribution chamber. The partition plate includes a communication hole through which the ejector-side distribution chamber and the tube-side distribution chamber are in fluid communication with each other. The partition plate includes a first portion, a second portion, a third portion, a fourth portion, and a fifth portion. The communication hole has an open area that is larger in each of the first portion, the third portion and the fifth portion than in each of the second portion and the fourth portion.

Abstract: A heat exchange system includes a heat exchanger, a radiator, a connecting member, a shutter, and a controller. The heat exchanger is configured to exchange heat between a heat medium circulating through a heat exchange cycle and an air introduced into an engine compartment. The radiator is configured to exchange heat between a cooling water and the air. The connecting member thermally connects between the heat exchanger and the radiator. The shutter is configured to selectively allow and prevent supply of air to the heat exchanger and the radiator. The controller is configured to determine whether a required heat absorption amount of the heat exchanger can be supplemented by a required heat dissipation amount of the radiator, and control the shutter to move in a closing direction upon determining that the required heat absorption amount can be supplemented by the required heat dissipation amount.

Abstract: A refrigerant evaporator has an interchange part. The interchange part connects a first collecting part of a second downstream tank part, and a second distribution part of a second upstream tank part. The interchange part connects a second collecting part of a second downstream tank part, and a first distribution part of a second upstream tank part. The interchange part swaps a refrigerant about a width direction of a core. Refrigerant passages relevant to the interchange part are configured to improve refrigerant distribution. Providing a plurality of passages and/or twisting a passage improve distribution.
