Cooling module for vehicle

Abstract

A cooling module for a vehicle may include a radiator that is disposed at a front side of a vehicle and exchanges heat with ambient air to cool coolant that flows therein, a first condenser in which refrigerant flows through a refrigerant pipe and that is disposed in the radiator and exchanges heat with the coolant flowing in the radiator to condense the coolant, and a second condenser that is connected to the first condenser through a refrigerant pipe, the refrigerant that is condensed by the first condenser flowing therein, and is disposed at a front side of the radiator and exchanges heat with ambient air to further condense the refrigerant.

What is claimed is: 
     
         1 . A cooling module for a vehicle, comprising:
 a radiator disposed at a front end of a vehicle exchanging heat with ambient air to cool coolant that flows therein;   a first condenser through which refrigerant flows including a first refrigerant flow tube disposed in the radiator exchanging heat with the coolant flowing in the radiator to condense the coolant; and   a second condenser operably connected to the first condenser by a refrigerant pipe through which the refrigerant condensed by the first condenser flows, the second condenser disposed at a front side of the radiator exchanging heat with ambient air to further condense the refrigerant.   
     
     
         2 . A cooling module for a vehicle of  claim 1 , wherein:
 the radiator includes:   a first header tank in which an inlet is formed to receive coolant;   a second header tank spaced from the first header tank and in which an outlet is formed to exhaust the coolant; and   a plurality of tubes connecting the first header tank with the second header tank are spaced from each other in a length direction of the first and second header tanks, and a heat radiating fin is disposed between the plurality of tubes.   
     
     
         3 . A cooling module for a vehicle of  claim 2 , wherein the inlet and the outlet respectively formed on the first header tank and the second header tank are disposed at opposite sides from each other. 
     
     
         4 . A cooling module for a vehicle of  claim 2 , wherein the first condenser is disposed in the second header tank. 
     
     
         5 . A cooling module for a vehicle of  claim 4 , wherein the first condenser includes:
 an inflow tank at one side of an inside of the second header tank connected to the refrigerant pipe at an outside of the second header tank through a refrigerant inlet receiving refrigerant;   an exhaust tank at an inside of the second header tank at a distance from the inflow tank connected to the refrigerant pipe at an outside of the second header tank through a refrigerant outlet exhausting refrigerant;   a first connection tank and a second connection tank disposed at the other side of an inside the second header tank to correspond to the inflow tank and the exhaust tank and are connected through a connection pipe; and   a plurality of refrigerant flow tubes connecting the inflow tank and the exhaust tank with the first connection tank and the second connection tank.   
     
     
         6 . A cooling module for a vehicle of  claim 5 , wherein a plurality of the refrigerant flow tubes include a plurality of barriers disposed at a uniform distance from each other along the length direction of the inflow tank, the exhaust tank, and the first and second connection tanks, and are alternatively disposed in a crossing manner along the length direction of the refrigerant flow tube to change flow direction of coolant flowing the second header tank. 
     
     
         7 . A cooling module for a vehicle of  claim 5 , wherein a heat radiating fin is disposed between the refrigerant flow tubes. 
     
     
         8 . A cooling module for a vehicle of  claim 2 , wherein the second condenser is disposed at a front upper portion of the radiator in a length direction. 
     
     
         9 . A cooling module for a vehicle of  claim 1 , wherein the second condenser includes a fin-tube type of heat exchanger. 
     
     
         10 . A cooling module for a vehicle of  claim 1 , wherein a receiver driver disposed on a refrigerant pipe connects the first condenser with the second condenser in a width direction of a vehicle to separate gaseous refrigerant remaining in the condensed refrigerant exhausted from the first condenser is disposed on the radiator. 
     
     
         11 . A cooling module for a vehicle of  claim 10 , wherein the first condenser is connected to the second condenser in series through the receiver drier.
