Problems solved by technology

[0003] However, in a general vehicle air conditioner, there is a problem that when the engine is stopped, the compressor driven by the engine stops, so that the refrigerant cannot be supplied to the evaporator, resulting in a sharp drop in cooling capacity.
However, if the length of the cold storage material container and the refrigerant flow pipe is increased, there is a problem that the heat exchange core of the evaporator is enlarged, the weight is increased, and the space-saving performance is impaired.
In addition, if the overall container height of the cold storage material container is raised without changing the size of the heat exchange core, there is a problem that the air passage area of ​​the ventilation gap becomes smaller and the ventilation resistance increases.

Abstract

An evaporator (1) with a cool storage function includes flat refrigerant flow tubes (13) and flat cool storage material containers (14) each brazed to one side surface of the corresponding refrigerant flow tube (13). A plurality of sets (15) each composed of refrigerant flow tubes (13) and a cool storage material container (14) are disposed such that they are spaced from one another. A fin (17) is disposed in an air-passing clearance (16) between adjacent sets, and is joined to the corresponding refrigerant flow tubes (13) and the corresponding cool storage material container (14). Front portions of the cool storage material containers (14) and the fins (17) project frontward from the refrigerant flow tubes (13), and an internal-volume-increasing portion (22), whose container height is greater than that of the container body portion (21), is provided at the frontward projecting portion of each cool storage material container (14). Fins (17) are brazed to opposite side surfaces of the internal-volume-increasing portion (22) of each cool storage material container (14).

Description

technical field [0001] The present invention relates to an evaporator with a cool storage function used in a vehicle air conditioner for temporarily stopping an engine that is a driving source of a compressor when the vehicle is stopped. Background technique [0002] In recent years, in order to protect the environment and / or improve the fuel economy of the motor vehicle, a motor vehicle that automatically stops the engine while waiting for a signal or the like to stop has been proposed. [0003] However, in general vehicle air conditioners, there is a problem that when the engine is stopped, the compressor driven by the engine stops, so that the refrigerant cannot be supplied to the evaporator, resulting in a sharp drop in cooling capacity. [0004] Therefore, in order to solve such a problem, it is conceivable to provide the evaporator with a cool storage function to cool the vehicle interior by using the cold energy stored in the evaporator when the engine is stopped and ...
