Apparatus for cooling power device of power conditioning system
The present invention relates to an apparatus for cooling a power device of a power conditioning system. To this end, the present invention comprises: a power device; an evaporator butted to the power device; and a modularized condenser which is connected with the evaporator, placed on the power device, and equipped on the upper side of the power conditioning system. Accordingly, the present invention may easily secure a space, make it easy to install, and increase heat emission performance of the condenser so as to keep the power device at a low temperature, thereby enabling the system to be stably operated over a long period of time.
1. An apparatus for cooling a power device of a power conditioning system, comprising:
a power device; and
an evaporator butted to the power device; and
a modularized condenser which is connected with the evaporator, placed on the power device, and equipped on an upper side of the power conditioning system,
wherein the modularized condenser comprises: a condenser casing; multiple rows of heat pipes equipped in the condenser casing; and multiple layers of heat dissipation plates connecting the respective multiple rows of heat pipes,
wherein the condenser casing has an entrance through which outside air flows inside and an exit through which exchanged heat is emitted outside in a form where only one side and the other side are open and reinforced flanges are formed at an edge of the entrance and that of the exit,
wherein the heat pipes are arranged repeatedly in a zigzag pattern inside the condenser casing and the condenser casing has a width longer than a height, so that heat exchange performance is improved, and
wherein each of the heat dissipation plates has: a ring spacer protruding upward or downward from a surface of each of the heat dissipation plates, each of the heat pipes is inserted into and combined with the respective spacer through soldering, so that, a regular space between the respective heat dissipation plates is maintained all the time; or
a splined hole, and each of the heat pipes is inserted into the splined hole, and combined with, the splined hole through soldering, so that a bonding liquid smoothly flows into a space between the splined hole and the respective heat pipe.
2. The apparatus of claim 1 , wherein the evaporator causes a fluid refrigerant, flowing through the respective heat pipe at a state of being decompressed to vacuum, to absorb heat generated from the power device and the refrigerant which has absorbed the heat at a gaseous state condenses through the condenser and is circulated to the evaporator.
3. The apparatus of claim 1 , wherein the respective heat pipe is arranged vertically in the condenser casing.
4. The apparatus of claim 1 , wherein the heat dissipation plates have at least one convex or concave surface.
