Title:
MEDICAL VARIABLE-TEMPERATURE WATER TANK
Document Type and Number:
WIPO Patent Application WO/2023/134050
Kind Code:
A1
Abstract:
A medical variable-temperature water tank, comprising a tank body (1), wherein a control panel is provided on an outer surface of the tank body (1), a detachable and movable water tank (2) is provided in the tank body (1), and a circulating working medium (3) is provided in the water tank (2); the temperature of the circulating working medium (3) in the water tank (2) is accurately controlled by means of two stages of variable-temperature temperature control loops; the primary variable-temperature temperature control loop comprises a circulating loop formed by a compressor (4), a heat conduction pipe (5), a reversing valve (6), and a surface-type heat exchanger (7), the surface-type heat exchanger (7) wrapping around the bottom of the water tank (2); and the secondary variable-temperature temperature control loop comprises a circulating loop formed by a water intake pipe (8), a water output pipe (9), an external circulating branch (10), and a semiconductor temperature control module (11), the water intake pipe (8) being provided with a circulating pump (12), the water output pipe (9) being provided with a recovery valve (13), one end of the water intake pipe (8) and one end of each water output pipe (9) being inserted into the circulating working medium (3), and the other end of the water intake pipe and the other end of the water output pipe being connected to the external circulating branch (10). The technical problem of existing variable-temperature water tanks in which a water inlet and a water outlet leak easily and thus cause contamination and produce harmful substances such as toxic aerosol is solved.
