Abstract:
1. A plate-type heat exchanger, comprising: a plate-type container of a workable metal material of a specific thermal conductivity; an airtightly structured hollow part formed in an interior of the container, the hollow part defining an inside surface portion; a heat medium sealed in the hollow part; a plurality of curved fins, each fin having a distal end and being spaced apart from at least one other fin along the inside surface portion, each said fin and the inside surface portion together defining a plurality of inset corners at least one of which is an acute angle; and a plurality of heat-medium-guiding grooves formed between the fins, the heat-medium-guiding grooves each having a width, defined between adjacent fins, that allows the heat medium to be moved along the heat-medium-guiding grooves by capillary force, each said groove having an inner closed end adjacent the inside surface portion, and an outer open end, each said fin gradually decreasing in thickness as each said fin extends and curves away from the inside surface portion to the distal end of said fin, such that the width of each said groove increases as the groove extends from the inner closed end of the groove to the outer open end of the groove; wherein the fins have a thickness of 0.1 mm to 1.0 mm and the inner closed end of each groove having a width of 0.01 mm to 1.0 mm, and each groove having a depth of 0.1 mm to 1.0 mm.
