Refrigerant heat dissipating apparatus
A refrigerant heat dissipation apparatus has an evaporator, a condenser having a first condensing tube and a second condensing tube, a first refrigerant tube, two second refrigerant tubes, and a refrigerant. The first refrigerant tube is connected between the top of the evaporator and an upper part of a first condensing tube. The second refrigerant tubes are respectively connected with a lower part of the first condensing tube and a lower part of the second condensing tube, so as to form a multi-flow closed-loop cycle. The refrigerant is filled into the multi-flow closed-loop cycle. The controlling of cycling direction of the refrigerant achieves the efficiency in heat dissipating of the refrigerant heat dissipation apparatus.
1. A refrigerant heat dissipation apparatus comprising:
an evaporator comprising:
a body;
an evaporation chamber disposed within the body;
a heat conducting element disposed at a bottom of the body;
a refrigerant exit at a top of the body and communicating with the evaporation chamber; and
two refrigerant entrances disposed at two side surfaces of the body respectively and communicating with the evaporation chamber, wherein the side surfaces are disposed at a height lower than the refrigerant exit and at two opposite sides of the refrigerant exit, and an entrance area of each of the refrigerant entrances is less than an exit area of the refrigerant exit;
a condenser comprising:
a first condensing tube and a second condensing tube arranged along a horizontal direction and spaced at an interval;
multiple heat dissipating tubes arranged from top to down and connected between the first condensing tube and the second condensing tube; and
multiple heat dissipating elements distributed on outer surfaces of the heat dissipating tubes and thermally contacting the outer surfaces of the heat dissipating tubes;
a first refrigerant tube comprising two ends connected with the refrigerant exit and an upper part of the first condensing tube respectively;
two second refrigerant tubes, each of the second refrigerant tubes comprising:
an inner diameter less than an inner diameter of the first refrigerant tube;
a first terminal connected with each of the refrigerant entrances; and
a second terminal opposite to the first terminal, wherein the second terminals of the second refrigerant tubes are respectively connected with a lower part of the first condensing tube and a lower part of the second condensing tube, so as to form a multi-flow closed-loop cycle by the evaporator, the condenser, the first refrigerant tube and the second refrigerant tubes; and
a refrigerant filled into the multi-flow closed-loop cycle.
