Using method of multi-circulation warm-stamping equipment

Abstract

The invention relates to a using method of multi-circulation warm-stamping equipment; the warm-stamping equipment comprises a high temperature chamber, a sample chamber and a low temperature chamber, which are sequentially connected, wherein a controllable door plate is arranged between the high temperature chamber and the sample chamber and between the sample chamber and the low temperature chamber respectively, the high temperature chamber is connected with a heating system, a containing chamber which can contain a condenser is arranged below the low temperature chamber and is connected with a refrigerating system, and another controllable door plate is arranged between the low temperature chamber and the containing chamber. The using method of the warm-stamping equipment is as follows: when a sample to be measured is in a high temperature testing phase, closing the controllable door plate between the low temperature chamber and the containing chamber, performing heating, defrosting, air drawing-off and dried air replenishing on the containing chamber; when the sample to be measured is in a low temperature testing, closing the heating system in advance, starting the refrigerating system and opening the controllable door plate between the low temperature chamber and the containing chamber; and in the method, continuous 80-time circular operation can be performed and the requirement of reliability accelerated test of photovoltaic modules can be met.

Description

Technical field [0001] The invention relates to the field of reliability testing of components or materials in the photovoltaic industry, in particular to a method for using a multi-cycle warming device. Background technique [0002] Among the existing technology’s reliability test methods for photovoltaic modules or materials, IEC61215 is the most important international standard. In this standard, the thermal cycle test (Thermal Cycle 200, hereinafter referred to as TC200) is a very important test. A total of 200 cycles are required. The temperature of each cycle ranges from -40°C to +85°C, and one cycle is completed within 9 hours. Therefore, the entire TC200 test cycle is as long as 1800 hours, which is a fast adaptation to the photovoltaic industry. The changing market has created certain restrictions. [0003] In order to solve the problems of TC200 testing, which can shorten the test cycle without sacrificing the test rigor, the industry is currently studying the use of the...
