Plate Heat Exchanger in The 1920s and Used in The Food Industry

Plate heat exchanger in the 1920s and used in the food industry. Compact heat exchanger made by the board hosted the effects of heat transfer, so they are being developed for a variety of forms. In the early 1930s, Sweden for the first time made  the spiral plate heat exchanger. Then the British with brazing legal system create a plate-fin heat exchanger made of copper and its alloy materials for aircraft engine cooling. The late 1930s, Sweden has to create the first shell heat exchanger, for the pulp mill. In the meantime, in order to solve the problem of the strong corrosion of the heat exchanger, heat exchanger made of new materials began to pay attention. Around the 1960s, due to the rapid development of space technology and cutting-edge science, urgently requires a variety of high-performance compact heat exchanger, coupled with the development of stamping, brazing and sealing technology, the heat exchanger manufacturing process has been further improved. so as to promote the vigorous development and wide application of a compact plate-surface heat exchanger. In addition, since the 1960s, in order to adapt to the needs of high temperature and pressure conditions of the heat exchanger and energy-saving, the typical shell and tube heat exchanger has also been further developed. The mid-1970s, in order to heat transfer enhancement on the basis of the heat pipe research and development, created out of the heat pipe heat exchanger. The heat exchanger according to the different mode of heat transfer can be divided into a hybrid, regenerative and partitions into three categories. Source: DAWN
