Document Type and Number:
WIPO Patent Application WO/2023/226413
Kind Code:
A1
Abstract:
A fluid machine and a heat exchange device. The fluid machine comprises a crankshaft (10), a cylinder sleeve (20), a cross groove structure (30), sliding blocks (40), and two flanges (50). The crankshaft (10) is provided with two eccentric portions (11); the crankshaft (10) and the cylinder sleeve (20) are eccentrically provided and an eccentric distance is fixed; the cross groove structure (30) is rotatably provided in the cylinder sleeve (20); two limiting channels (31) of the cross groove structure (30) are sequentially provided in an axial direction of the crankshaft (10), and an extending direction of each limiting channel (31) is perpendicular to the axial direction of the crankshaft (10); the two eccentric portions (11) correspondingly extend into two through holes (41) of two sliding blocks (40), and the two sliding blocks (40) are correspondingly slidably provided in the two limiting channels (31) and variable volume cavities are formed. The two flanges (50) are respectively provided at two axial ends of the cylinder sleeve (20), one of the two flanges (50) is provided with an air inlet channel (54), the cylinder sleeve (20) is provided with a radial air suction hole (21), and the air inlet channel (54) and the radial air suction hole (21) are respectively communicated with two variable volume cavities. Therefore, air suction reliability of the fluid machine is ensured, and air suction loss caused by insufficient air suction of the fluid machine is avoided.
