したことを特徴とする膨張弁付エバポレータ。[Claim for Utility Model Registration] At least two tank sections in which refrigerant is temporarily stored, a refrigerant flow path communicating between the at least two tank sections, and an air flow path for air circulation formed between the refrigerant flow paths. In an evaporator with an expansion valve that has a space and an expansion valve that sends the throttled and expanded refrigerant to either of the tank parts, the inlet side tank part 35 and the outlet side tank part 36 of the tank parts are combined into a single tank. Pipe material 37, 37
The inlet-side communication passage 38 and the outlet-side communication passage 39, which are partitioned and formed inside a so as not to communicate with each other, are communicated with each other, and the inlet-side communication passage and the outlet-side communication passage are connected to the pipe materials 37, 37a. An expansion valve mounting seat 42 having an inflow opening 43 and an outflow opening 44 that communicate with each other is formed facing the front or rear surface in the direction of air circulation flowing in the air circulation space 4, and An expansion valve block 45 is provided on the valve mounting seat 42, in which a valve body 48 that throttles and expands the refrigerant and a temperature sensing part 50 that adjusts the opening degree of the valve body are formed.
An evaporator with an expansion valve characterized in that the inflow opening 43 and the outflow opening are connected to communicate with the valve body 48 and the temperature sensing section 50, respectively.
