Radiator and cooling unit

Abstract

A radiator for dissipating heat by liquid coolant flowing includes a plate including at least two flat sections parallel to each other, a flection connecting the flat sections, a passage configured within the two flat sections and the flection to allow the liquid coolant to flow from a first opening to a second opening provided at each end of the two flat sections, the two flat sections opposed to each other, and the plate including a plurality of fins; an inlet tube having an opening formed so as to fit the first opening and an end opening for allowing the liquid coolant to flow in the passage; and an outlet tube having an opening so as to fit of the second opening and an end opening for allowing the liquid coolant to flow out the passage. The outlet tube is disposed in parallel with the inlet tube.

1 . A radiator for dissipating heat by the use of liquid coolant flowing therein comprising:
 a plate including at least two flat sections parallel to each other, a flection connecting the flat sections, a passage configured within the two flat sections and the flection to allow the liquid coolant to flow from a first opening to a second opening provided at each end of the two flat sections, the two flat sections opposed to each other, the plate including a plurality of fins outside thereof;   an inlet tube having an opening formed along a longitudinal direction thereof so as to fit the first opening and an end opening for allowing the liquid coolant to flow in the passage; and   an outlet tube having an opening formed along a longitudinal direction thereof so as to fit of the second opening and an end opening for allowing the liquid coolant to flow out the passage, the outlet tube disposed in parallel with the inlet tube, wherein each longitudinal direction of the inlet tube and the outlet tube are in parallel with at least one of each surface of the two flat sections.   
   
   
       2 . The radiator according to  claim 1 , wherein the plurality of fins are disposed between the two flat sections. 
   
   
       3 . The radiator according to  claim 1 , further comprising a shroud around a perimeter of the plate and the plurality of fins disposed between the two flat sections and between the shroud and each of the two flat section. 
   
   
       4 . A cooling unit for dissipating heat by the use of liquid coolant flowing comprising:
 a radiator including,
 a plate including at least two flat sections parallel to each other, a flection connecting the flat sections, a passage configured within the two flat sections and the flection to allow the liquid coolant to flow from a first opening to a second opening provided at each end of the two flat sections, the two flat sections opposed to each other, the plate including a plurality of fins outside thereof, 
 an inlet tube having an opening formed along a longitudinal direction thereof so as to fit the first opening and an end opening for allowing the liquid coolant to flow in the passage, and 
 an outlet tube having an opening formed along a longitudinal direction thereof so as to fit of the second opening and an end opening for allowing the liquid coolant to flow out the passage, the outlet tube disposed in parallel with the inlet tube, wherein each longitudinal direction of the inlet tube and the outlet tube are in parallel with at least one of each surface of the two flat sections; 
   a cooling jacket for transferring heat generated by electronic components to the liquid coolant following therein; and   a pump for circulating the liquid coolant between the cooling jacket and the radiator.   
   
   
       5 . The cooling unit according to  claim 4 , wherein the pump includes a suction tube for sucking the liquid coolant in the cooling jacket and a discharge tube for discharging the liquid coolant into the cooling jacket, the suction tube and the discharge tube are disposed substantially parallel to each other, the inlet tube and the suction tube are disposed substantially on a straight line along a direction, and the outlet tube and the discharge tube are positioned substantially on a straight line along the direction. 
   
   
       6 . The cooling unit according to  claim 4 , further comprising a cooling fan for blown air toward to a space surrounded with a board. 
   
   
       7 . A cooling unit for dissipating heat by the use of liquid coolant flowing comprising:
 a cooling jacket for transferring heat generated by an electronic component to the liquid coolant;   a radiator for dissipating heat from the liquid coolant, the radiator including an inlet tube for introducing the liquid coolant from the cooling jacket and an outlet tube for discharging the liquid coolant into the cooling jacket; and   a pump for circulating the liquid coolant between the cooling jacket and the radiator, the pump including a suction tube for suctioning the liquid coolant from the cooling jacket and a discharge tube for discharging the liquid coolant into the cooling jacket, plate including at least two flat sections parallel to each other, wherein the inlet tube and the suction tube are disposed substantially on a straight line along a direction, and the outlet tube and the discharge tube are positioned substantially on a straight line along the direction.
