US Patent 10989453 Heat exchanger with improved heat removing efficiency

A heat exchanger includes a heat-absorbing part, two vapor conduits, a return conduit and a condensing part. The heat-absorbing part includes a vapor zone and a liquid zone. A first end of each vapor conduit is connected with the vapor zone of the heat-absorbing part. A first end of the return conduit is connected with the liquid zone of the heat-absorbing part. The condensing part includes a vapor-inputting chamber, a liquid-outputting chamber, a partition plate, a communication chamber, a first condenser tube group and a second condenser tube group. The vapor-inputting chamber is connected with a second end of each vapor conduit. The liquid-outputting chamber is connected with a second end of the return conduit. A loop is defined by the heat-absorbing part, the at least two vapor conduits, the return conduit and the condensing part collaboratively.
