Water supply tank for heat exchanger

Abstract

A pipe of a header pipe is formed by combining two separated bodies separated along a longitudinal direction. The first separated body has a tube holding wall portion including an insertion hole inserting a flat tube thereto, and a pair of straight portions protruded from the tube holding wall portion in an approximately orthogonal direction and set along both sides in a width direction of the tube, and is formed in a C-shaped cross sectional shape.

Description

technical field [0001] The invention relates to an upper water tank of a heat exchanger such as a condenser applied to an air conditioner such as an automobile. Background technique [0002] Figure 1 and figure 2 A conventional heat exchanger (condenser) used on an air conditioner is shown (Japanese Unexamined Patent Application No. H7-027496). As shown in Figure 1, the condenser 1 consists of a pair of opposite upper water tanks 11 and 12, a plurality of flat tubes 13 arranged between the upper water tanks 11 and 12, and a corrugated heat dissipation tube inserted between the flat tubes 13 and 13. Composition of 14 pieces. [0003] Each header tank 11 and 12 is composed of a pipe 15 , a closure member 16 closing the open portions at both ends of the pipe 15 , and a partition plate 17 for dividing a channel extending longitudinally in the pipe 15 . In this embodiment, the closure 16 doubles as a connection to either the outlet or inlet pipe. [0004] Figure 1 and figure...

Problems solved by technology

On the other hand, in the case where the diameter of the tube 15 is small in order to make the condenser 1 compact, there is a problem that the passage cross-sectional area S of the tube 15 cannot be sufficiently secured.
