Title:
TWO-STAGE REFRIGERATION MODULE AND PHOTON BEAUTY INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2024/082434
Kind Code:
A1
Abstract:
A two-stage refrigeration module (1) and a photon beauty instrument (100). The two-stage refrigeration module (1) comprises a first-stage semiconductor refrigeration member (10'), a second-stage semiconductor refrigeration member (10), and a cold conduction member (15), wherein the first-stage and second-stage semiconductor refrigeration members (10'/10) each comprise a galvanic couple layer (12) in the middle, and a hot surface (11') and a cold surface (13) at two ends; the cold conduction member (15) is connected between the first-stage semiconductor refrigeration member (10') and the second-stage semiconductor refrigeration member (10) in a manner of rapidly conducting cold; and the cold conduction member (15) is a heat transfer structural member. The photon beauty instrument (100) uses the two-stage refrigeration module (1), wherein the first-stage semiconductor refrigeration member (10') is directly used as a working surface at the front end of the photon beauty instrument (100) or refrigerates the working surface at the front end of the photon beauty instrument (100). By using the two-stage refrigeration module (1), the problem of refrigeration speed being reduced due to unequal heat conduction efficiency, slow heat conduction and poor heat conduction timeliness when the first-stage semiconductor refrigeration member (10') dissipates heat by means of the heat transfer structural member, the problem of a heat dissipation effect of a fan being affected by heat imbalance between the front and rear ends, the left and right ends or the upper and lower ends of a heat dissipation sheet when heat is conducted to the heat dissipation sheet, etc., can be solved.
