Description

Technical Field

[0001] This utility model belongs to the field of cavitation heat pump technology, specifically a cavitation heat pump with a sound insulation structure. Background Technology

[0002] Cavitation refers to the formation, development, and collapse of gas cavities within a liquid or at the liquid-solid interface when local pressure decreases. When liquid pressure drops to or below its saturated vapor pressure, a large number of cavitation bubbles are generated due to the vigorous vaporization of the liquid. These cavitation bubbles expand and grow with the liquid flow. When the liquid pressure recovers, the cavitation bubbles collapse instantaneously, forming microjets and shock waves, generating instantaneous local high temperatures and pressures. The energy released by cavitation can also be utilized to enhance chemical and physical processes, achieving effects such as increased efficiency, energy saving, and reduced consumption.

[0003] A search revealed that patent CN218846271U discloses a cavitation heat pump and heating equipment, belonging to the field of heating equipment modification technology. The driving device is a water-cooled motor, including a motor rotor, a water-cooled base, and a winding stator. The motor rotor and winding stator are housed within the water-cooled base, which has a water-cooling cavity along its circumference. The outer surface of the water-cooled base has an outlet B and an inlet B at its upper and lower ends, respectively. The inlet B and outlet B communicate with the water-cooling cavity to form a water cooling channel. The motor rotor's power output end is connected to the rotating shaft. The inlet A and outlet B are connected by a connecting pipe. This utility model has the following advantages: simple overall structure, space-saving, high heating efficiency, fast heating speed, immediate use, and all-weather, all-time use. With water evenly distributed through multiple outlets, the heating effect is better ensured compared to cavitation heat pumps without a water distributor before entering the cavitation stator.

[0004] When existing cavitation heat pumps are in use, a large number of cavitation bubbles are generated due to the violent vaporization of the liquid, and the energy released by the cavitation phenomenon will generate a lot of noise. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of this utility model are:
