Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, and in particular to a heat dissipation mechanism and a multi-layer laminator for solar cell modules. Background Technology

[0002] With the rapid development of the photovoltaic power generation industry, the requirements for the efficiency and quality of photovoltaic module production equipment are also increasing. As a key piece of equipment in photovoltaic module production, the laminator is mainly used to laminate solar cells, EVA film, glass and backsheet materials together. Through processes such as heating, vacuuming, and pressurizing, the materials of each layer are tightly bonded to form a stable and durable photovoltaic module.

[0003] However, because the heating modules and transmission systems of each layer generate continuous heat during the lamination process, the heat inside the equipment often accumulates rapidly, forming high temperatures. If this accumulated heat is not dissipated in time, it will not only affect the temperature control accuracy of each layer, leading to quality fluctuations in the laminated products, but also accelerate the aging of key components and shorten the service life of the equipment.

[0004] Traditional multi-layer laminators mostly use simple air-cooling systems, which not only have high energy consumption, greatly increasing equipment operating costs, but also have the problem of low heat dissipation efficiency. Utility Model Content
