Abstract

A double-half-cell efficiency testing device, comprising a first conveying mechanism (1), a feeding and transferring mechanism and a rotating mechanism (3) which are arranged in sequence. The first conveying mechanism (1) comprises two first conveying lines (11) arranged side by side and respectively used for conveying cells; the feeding and transferring mechanism comprises a first transfer assembly (2); the rotating mechanism (3) comprises a rotating table (31) which is rotatably provided; the rotating table (31) is circumferentially provided with a plurality of working surfaces (32), and can drive the working surfaces (32) to sequentially rotate to a feeding station (100), a testing station (200) and a discharging station (300); the first transfer assembly (2) simultaneously transfers cells on the two first conveying lines (11) to the working surface (32) at the rotating mechanism (3), so as to simultaneously test the two cells.

Abstract

The present utility model relates to the technical field of solar cell heat treatments. Disclosed are an auxiliary combustion device and a sintering apparatus. The auxiliary combustion device specifically comprises: a combustion box having a combustion cavity; a heat exchange box, which has a gas inlet in communication with a gas outlet of the combustion box to cool hot gas flow discharged from the combustion box; and a heat insulation assembly, which is arranged in the combustion box and close to one side of the gas outlet of the combustion box in order to reduce heat loss in the combustion box. The purpose of same is to reduce the heat loss in the combustion cavity and reduce the energy consumption of the apparatus.

Abstract

The present utility model relates to the technical field of solar cell heat treatment, and disclosed are a combustion apparatus and a sintering device. The combustion apparatus specifically comprises: a combustion box body having a combustion chamber, a heat exchange box body having a gas inlet that is in communication with a gas outlet of the combustion box body and is used for cooling a hot gas flow discharged from the combustion box body, and a cooling assembly arranged on the side of the gas outlet of the combustion box body and used for cooling the hot gas flow in the heat exchange box body when the heat exchange box body ceases operation. The aim of the present utility model is to continue to cool the high temperature gas produced in the combustion chamber when a water cooling device ceases operation, preventing damage to the water cooling device.
