Patent number: 6272881Abstract: An evaporator has plural tubes arranged in parallel with each other in a width direction perpendicular to an air flowing direction. The tubes are further arranged in a plural rows in the air flowing direction, and tank portions extending in the width direction are arranged in the plural rows in the air flowing direction to correspond to the tubes. In the evaporator, refrigerant flows through a zigzag-routed refrigerant passage formed by the tank portions and the tubes. A partition wall defining adjacent two tank portions in the air flowing direction has plural bypass holes through which the adjacent two tank portions directly communicate with each other. Therefore, the zigzag-routed refrigerant passage of the evaporator is readily formed without an additional side passage or the like. Thus, the number of components of the evaporator is reduced thereby simplifying the structure of the evaporator, and pressure loss of refrigerant flowing in the evaporator is decreased.Type: GrantFiled: April 1, 1999Date of Patent: August 14, 2001Assignee: Denso CorporationInventors: Isao Kuroyanagi, Masamichi Makihara, Toshio Ohara, Sadayuki Kamiya

Patent number: 6182741Abstract: An air conditioner includes a case accommodating an evaporator having a core portion and a lower tan disposed at a bottom of the core portion. The case has a recess portion disposed at an upstream air side of the evaporator, and a covering wall is formed to extend upwardly from the bottom of the recess portion to cover only the lower tank at an immediately upstream air side. When air passes through the evaporator, alien substances contained in air collide with the evaporator and fall to be deposited in the recess portion. Therefore, the deposition of the alien substances do not directly adhere to the lower tank of the evaporator to prevent the evaporator from being corroded.Type: GrantFiled: February 25, 1998Date of Patent: February 6, 2001Assignee: Denso CorporationInventors: Keiichi Yoshii, Sadayuki Kamiya
