Document Type and Number:

WIPO Patent Application WO/2021/025153

Kind Code:

A1

Abstract:

The purpose of the present disclosure is to suppress noise generated by the rotation of a propeller fan.　A heat source unit (3) for a refrigeration device (1) comprises a casing (50), a heat exchanger (60), and a propeller fan (70). A suction port (53) is formed on the back and one side of the casing (50), and an outlet (52) is formed on the front of the casing (50). A partition plate (51) forming an air passage (A) faces the one side of the casing (50). The heat exchanger (60) is provided along the suction port (53). A first distance S1, which is the shortest distance between an outer circumferential circle (v) of the propeller fan (70) and a second portion (62) of the heat exchanger (60), and a second distance S2, which is the shortest distance between the outer circumferential circle (v) of the propeller fan (70) and the partition plate (51), satisfy the following relationship: 6 ≤ S1/S2.
