摘要:
A receiver includes a cylindrical main tank; a cylindrical internal thread component having an internal thread; a cap having a male thread threaded with the internal thread; a sealing attached to the cap; and a filter portion arranged in the cap. The internal thread component is coaxially arranged to an inner circumference face of the tank. The filter portion includes an internal passage extending inside of the cap, and a net that collects a foreign matter contained in refrigerant flowing through the internal passage.

摘要:
In a high-pressure side heat exchanger for a vapor compression refrigerant cycle, a refrigerant passage is formed such that a flow area (S), a length (L), and an equivalent diameter (d) satisfy the conditional expression 0.04×e−1.8d≦S/L≦2.1×e−1.8d. The flow area (S) is obtained by dividing the product of a total cross-sectional area of the passages in one tube and the number of tubes by the path number. The length (L) is a flow distance of the refrigerant from the refrigerant inlet to the refrigerant outlet. That is, the length (L) is obtained by the product of the length of the tube and the path number. The diameter (d) is obtained by dividing the product of four and the cross-sectional area of the passage by a circumference of the passage.

A heat exchanger includes aligned tubes and upper and lower header tank units, each of which includes two fluid conduits communicated with the tubes. Each header tank unit further includes an intermediate plate, which defines a plurality of communication holes therethrough. Each communication hole communicates between a corresponding one of the tubes and a corresponding one of chambers defined by the fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the chambers.
