Condenser

Abstract

A condenser includes first and second header tanks provided at one end thereof such that the latter is located on the outer side of the former. First heat exchange tubes forming a first heat exchange path provided in a condensation part are connected to the first header tank. Second heat exchange tubes forming a second heat exchange path provided in a super-cooling part are connected to the second header tank. The first header tank has one communication section which communicates with the second header tank through a communication part and to which all the heat exchange tubes forming the first heat exchange path are connected. The communication part is provided at a height below the uppermost heat exchange tube among all the heat exchange tubes connected to the communication section. The upper end of the first header tank is located above the lower end of the second header tank.

1 . A condenser which has a condensation part and a super-cooling part provided such that the condensation part is located above the super-cooling part and which comprises a plurality of heat exchange tubes disposed in parallel such that their length direction coincides with a left-right direction and they are spaced apart from one another in a vertical direction; and header tanks which are disposed such that their length direction coincides with the vertical direction and to which left and right end portions of the heat exchange tubes are connected, each of the condensation part and the super-cooling part including at least one heat exchange path formed by a plurality of heat exchange tubes successively arranged in the vertical direction, the condenser configured such that all refrigerant having flowed through the heat exchange tubes of the condensation part flows into the heat exchange tubes of the super-cooling part,
 wherein a first header tank to which all the heat exchange tubes of the condensation part are connected and a second header tank to which all the heat exchange tubes of the super-cooling part are connected are provided at one of left and right ends of the condenser; the first header tank has one communication section which communicates with the second header tank through a communication part and to which all the heat exchange tubes forming one heat exchange path are connected; the communication part is provided at a height below the uppermost heat exchange tube among all the heat exchange tubes connected to the communication section; the second header tank is disposed on the outer side of the first header tank with respect to the left-right direction; an upper end of the second header tank is located above a lower end of the first header tank; the second header tank has a function of separating gas and liquid from each other and storing the separated liquid; and all the refrigerant having passed through the heat exchange tubes of the condensation part flows into the communication section of the first header tank and flows into the second header tank through the communication part.   
     
     
         2 . A condenser according to  claim 1 , wherein the condensation part has one heat exchange path; the first header tank has one communication section to which all the heat exchange tubes forming the heat exchange path of the condensation part are connected; and the communication part establishes a refrigerant communication between the second header tank and a portion of the communication section of the first header tank, the portion extending downward from an approximate center of the communication section with respect to the vertical direction. 
     
     
         3 . A condenser according to  claim 1 , wherein the condensation part has two or more heat exchange paths; the condenser is configured such that refrigerant flows from a heat exchange path at one end with respect to the vertical direction toward a heat exchange path at the other end with respect to the vertical direction; the first header tank has one communication section to which all the heat exchange tubes forming a furthest downstream heat exchange path of the condensation part are connected; and the communication part establishes a refrigerant communication between the second header tank and a portion of the communication section of the first header tank, the portion extending downward from an approximate center of the communication section with respect to the vertical direction.
