  • Patent number: 10215459
    Abstract: Disclosed herein is a vehicle condenser in which a notch portion of each coupling part of a pair of supports installed at the outermost sides of radiation fins extends so as to have a certain length from the tip of a body part to the inside end of the notch portion, or a through-hole is formed so as to be spaced by a predetermined distance toward the inside of the body part from the tip thereof, thereby preventing the radiation fins from melting when the clad on a header of a header tank is melted during the brazing of the radiation fins and flows along an embossing part, regardless of a method for manufacturing the supports. Consequently, it is possible to reduce the failure rate of the condenser and increase the efficiency of the condenser by maintaining the original state of the radiation fins.

  • Patent number: 10215508
    Abstract: A tank for a heat exchanger includes a casing including a substantially planar header opening formed therein and a foot disposed around a perimeter of the header opening. The foot forms an outwardly extending flange from which a pair of oppositely arranged walls extend, the oppositely arranged walls forming an arcuate shape including a spine extending along an apex of the arcuate shape. The oppositely arranged walls each have a corrugated profile adjacent the foot due to the presence of outwardly projecting ribs formed in the oppositely arranged walls. Each of the ribs extend lengthwise from the foot toward the spine, wherein a distal end of each of the ribs is formed adjacent a neutral stress portion of the casing which undergoes a minimal stress when the casing is subjected to an internal pressure from a fluid flowing there through.
