THICKFILM ELEMENT WITH HIGH THERMAL CONDUCTIVITY FROM BOTH PARTIES

摘要

In the present invention disclosed thick film element with high thermal conductivity on both sides, which includes a carrier, a thick film coating deposited on the carrier, and a protective layer deposited on the coating; the thick film coating is a heating material, and the heating is carried out by electrical heating, with the carrier, the thick film coating and the protective layer being chosen from materials that satisfy the following inequalities: Q≥Q; Q≥Q; and Q = a × Q, Q = b × Q, Q = c × Q; and 0.1≤a≤150, 1≤b≤2500, 100≤c≤10000; The thick film element of the present invention has both sides with high thermal conductivity, with the same heat release rate on both sides, thereby improving the heat transfer efficiency of the product; it can be used in products requiring the use of products with high thermal conductivity on both sides, and largely satisfies the market demand for multifunctional heating products.
