Title:
MULTI-CHANNEL PARALLEL EMISSION OPTICAL DEVICE AND THERMOELECTRIC COOLER
Document Type and Number:
WIPO Patent Application WO/2021/031330
Kind Code:
A1
Abstract:
The present invention relates to a multi-channel parallel emission optical device and a thermoelectric cooler. The area of a cold face of the thermoelectric cooler completely covers the area of a hot face; when the hot face and the cold face are horizontally arranged, there is a horizontal distance between an edge of the cold face and an edge of the hot face; and a positive electrode and a negative electrode are fixed on a second surface of the cold face. The thermoelectric cooler of such a structure is arranged in a BOX-encapsulated tube shell; a groove for mounting the thermoelectric cooler is provided in a bottom face of an inner wall of the tube shell; the hot face of the thermoelectric cooler is fixed to the bottom of the groove; an insulating low-thermal-conductivity seal ring is arranged between a lower end of the cold face of the thermoelectric cooler and the tube shell; the tube shell, the insulating low-thermal-conductivity seal ring, and the cold face of the thermoelectric cooler form a closed space, so as to achieve the effect of localized airtightness of the TEC; a TEC body does not need a waterproof film; and it can be guaranteed that the TEC works in a non-airtight environment.
