Claims

[Claims for Utility Model Registration] A concave portion is provided in the plates 22, 23 so that the evaporation portion formed in the plates 22, 23 is directed from one end to the other end at the center portion of the plates 22, 23 in the width direction. A first and second tank section 24 is divided into a first evaporation section 32 and a second evaporation section 33 by an extending longitudinal partition wall 31, and communicates with the first and second evaporation sections 32 and 33, respectively. , 25 are formed at the one end of the plates 22, 23, and a communication section 34 for communicating the first and second evaporation sections 32, 33 is formed at the other end of the plates 22, 23. In a stacked evaporator formed by stacking a plurality of plates 22, 23 so that their concave portions face each other to form an evaporator main body 3 having an evaporation section and a tank, the one end of the plates 22, 23 has the following steps: , a third tank section 26 located on the second evaporation section 33 side and separated from the evaporation section 33 is connected to the third tank section 2
6 and the first tank part 24, and the plates 22 and 23 are stacked with the left and right sides of the evaporator main body 3 inverted, so that the second tank part 25 is partitioned in the front-rear direction. evaporation section and tanks divided into front, center, and rear, two on the left and right, 9 to 12
, 13 to 18, and each tank 13, 16, 14 adjacent to the left and right
and 17, 15 and 18, the middle tank 14,1
The refrigerant pipes 6 and 7, which guide the refrigerant, are connected to the ends of the evaporator main body 3 in the same direction. to the front and rear tanks 13, 15, and from the evaporator sections 9, 11 on the downstream side of the air flow passing through the evaporator main body 3 to the evaporator section 1 on the upstream side.
A stacked evaporator characterized in that a refrigerant flows through ports 0 and 12.
