Abstract

PURPOSE:To prevent the heat exchanging capacity from a lowering due to too small feeding rate or discharge rate of refrigerant, by determining one sectional area at least of an inlet pipe and an outlet pipe for refrigerant larger than the sectional area of a tube body. CONSTITUTION:A refrigerant inlet pipe 8 is made of round pipe, equipped with a connector 18 for piping connection at its end. The sectional area of the body of such a refrigerant inlet pipe 8 is determined larger than that of a tube 1, so that it can secure a predetermined feeding rate of refrigerant. But it is determined smaller than the sectional area of the body of a header 5, because the increase in the heat exchanging efficiency cannot be expected even if that of an inlet pipe 8 is determined larger than that of a header 5. In case that the title heat exchanger is used as an evaporator, the refrigerant is to be flowed in the reverse direction by making the refrigerant inlet pipe 8 an outlet pipe, and a refrigerant outlet pipe 9 an inlet pipe. The sectional area of the body of a refrigerant outlet pipe 8 in the evaporator is to be determined larger than that of a tube 1, and it is made smaller than that of a hollow header 5.

Conventional Technology For example, heat exchangers for condensers used in the above-mentioned applications have traditionally been made by bending a multi-hole extruded flat tube called a harmonica tube into a serpentine shape and arranging fins between the parallel parts. A so-called serpentine heat exchanger with a core made up of However, in the serpentine heat exchanger, the refrigerant passage for heat exchange is formed by a single flat extruded tube, so a large passage area cannot be secured, and the extruded tube is bent in a meandering shape. Because of this, the radius of curvature of the bent part cannot be reduced beyond a certain level, so the tube pitch cannot be reduced.
For this reason, the number of fins interposed between the parallel portions of the tube is small, resulting in poor fin efficiency, which limits the improvement in heat exchange efficiency.

Therefore, as a heat exchanger to replace the serpentine type, flat tubes and corrugated fins are stacked in an alternating arrangement.
A heat exchanger has been proposed in which both ends of a tube are connected to a hollow header. According to this heat exchanger, since the tube pitch can be freely selected, a large cross-sectional area of the refrigerant passage can be ensured, and the number of fins interposed between each tube can be increased, resulting in a small size and excellent heat exchange efficiency. can be done.

Problem to be Solved by the Invention By the way, in the latter heat exchanger, the method of flowing the heat exchange refrigerant involves dividing the inside of one or both headers into a plurality of partitions, and dividing the inside of one or both headers into a plurality of partitions belonging to each partition. One has a configuration in which the refrigerant flow is reversed and meandering for each tube, and one of both headers is used as an inlet header and the other as an outlet header.
There is a type of refrigerant in which the refrigerant supplied to the inlet header is distributed to all the tubes and flows in a straight line to the outlet header. In either case, if the amount of refrigerant supplied from the refrigerant inlet pipe of the header is too small, the pressure loss will be small and the heat exchanger will not be able to fully demonstrate its performance.
