Abstract

PURPOSE:To improve the heat exchange efficiency of the condenser by providing partition plates in the inner parts of headers and partitioning a coolant passage constituted of tubes into at least tow or more passage groups and causing a coolant to meander at least once or more and thus to circulate. CONSTITUTION:A coolant flowing in the condenser via a upper inlet pipe 6 of a lefthand header 3 passes respective tubes 1 of an inlet side passage group A and reaches a righthand header 4. Thereafter, the coolant is reversed and flows into a lefthand header 3 via respective passages of an intermediate passage group B, and further is reversed and flows into a righthand header via respective passages of an outlet side passage group C and flows out of the condenser via an outlet pipe 8. While circulating among respective passage groups, the coolant is heat exchanged with air circulating in the direction W within air circulating gaps including corrugated fins 2 formed between tubes 1 and 1. Partition plates 10 and 11 are provided at a position slightly upper than the central part of the lefthand header 3 and at a position approximately 1/3 of the full length from the lower end of the righthand heater 4.

Problems to be Solved by the Invention However, in such a serpentine type condenser, the refrigerant passage is formed by a single flat extruded tube, so the overall size of the condenser is limited due to installation space, etc. In some cases, it is not possible to secure a large passage area, so there is a limit to the reduction in heat exchange efficiency (-1) pressure loss. However, since it is made by bending an extruded tube into a meandering shape, the radius of curvature of the bent part cannot be made smaller than a certain level, and the pitch of the tube cannot be made small. As a result, the fin efficiency was poor, and it was extremely difficult to improve the heat exchange efficiency.

Effects of the Invention As described above, the condenser according to the present invention adopts a structure in which tubes and corrugated fins are stacked in an alternating arrangement, and a header is connected to both ends of the tube, and a partition plate is provided inside the header. The refrigerant passage is divided into two or more passage groups including an inlet open passage group and an outlet side passage group, and the refrigerant flows in a meandering manner at least once. Not only does it form a meandering path similar to that of a serpentine condenser, but it also eliminates the inconvenience of a serpentine condenser, which is limited by the radius of curvature of the bending part and is therefore limited by the tube pitch. You can select the appropriate tube pitch. Therefore, if the number of meandering passages and the overall length of the refrigerant passage are the same, the number of corrugated fins interposed between adjacent tubes can be significantly increased by reducing the tube pitch, which improves fin efficiency and improves heat efficiency. Exchange efficiency can be improved. Moreover, since the cross-sectional area of the passage becomes large, pressure loss can be reduced. Furthermore, since the tube has a partition wall inside it, this partition wall also functions as a reinforcing material, improving the pressure resistance of the condenser and ensuring durability without the risk of destruction. Another effect is that it is possible to provide an excellent condenser.
