Description

Heat pipe

The present invention relates to a heat pipe, and more particularly, to a heat pipe for transferring heat.

In recent years, various methods for recovering energy for energy saving have been introduced in the field of air conditioners. Among the above methods, a heat pipe is used as one of the methods for recovering the arrangement.

The heat pipe is formed by forming the inside of the heat pipe in a vacuum state and then putting a heat exchange fluid such as water or alcohol into the heat pipe. The heat pipe has a substantially rod shape. When the lower portion of the heat pipe is heated, the heat exchange fluid is converted to a gaseous state and flows upward by a density difference. When the heat pipe is cooled at an upper portion, the heat pipe is radiated to be condensed into a liquid state and returned to the lower portion by gravity. By repeating the above process, heat energy is transferred from the heat pipe.

However, since the heat pipe has a substantially rod shape, it is difficult to apply the heat pipe in various ways due to the restriction of the shape.

The present invention provides a heat pipe that can be used in various types of air conditioning systems and cooling systems.

The heat pipe according to the present invention comprises an evaporator for absorbing external heat to evaporate a fluid for heat exchange and an inlet end connected to the evaporator and connected to the evaporator for flowing the evaporated heat exchange fluid, And a heat dissipating unit having an outlet end through which the fluid for use is discharged and discharging the latent heat of condensation while condensing the vaporized heat exchange fluid.

According to embodiments of the present invention, the heat dissipation unit may be disposed above the evaporation unit.

According to an embodiment of the present invention, the heat dissipating unit may have a reduced cross-sectional area from the inlet end to the outlet end.

According to one embodiment of the present invention, the evaporator and the radiator may have a closed curve shape.

The heat pipe according to the present invention is arranged such that the heat radiating portion is disposed above the evaporator and the sectional area decreases from the inlet end to the outlet end of the heat radiating portion. Accordingly, the heat exchange fluid can be introduced into the heat dissipation unit through an inlet end having a relatively large cross-sectional area after being evaporated in the evaporation unit. In addition, the vaporized heat exchange fluid can move from the inlet end to the outlet end due to the pressure difference between the inlet end and the outlet end. The heat exchanging fluid condensed while moving from the inlet end to the outlet end may be introduced into the evaporator through the outlet end by gravity in a liquid state. Therefore, the heat-exchanging fluid in the heat pipe can easily circulate between the evaporator and the heat-dissipating unit while changing state.

On the other hand, the heat pipe has a closed curve shape. Accordingly, the shape of the heat pipe can be variously changed by extending or bending the length of the heat dissipation unit. Therefore, the utilization of the heat pipe can be improved by mounting the heat pipe at various positions.

FIG. 1 is a schematic perspective view for explaining a heat pipe according to an embodiment of the present invention, and FIG. 2 is a schematic perspective view for explaining another example of the evaporator shown in FIG.

1 and 2, the heat pipe 100 includes an evaporator 110 and a heat radiating part 120. [

A heat exchange fluid (not shown) is provided in the evaporator 110 and the heat dissipation unit 120. Depending on the temperature condition in which the heat pipe 100 is used, various kinds of the heat exchange fluids may be used. In general, examples of the fluid for heat exchange include freon, ammonia, acetone, methanol, ethanol, water and the like having a relatively low boiling point.

The evaporator 110 absorbs external heat to evaporate the heat exchange fluid.

The evaporator 110 may have a hollow cylindrical shape as shown in FIG. 1, or may have a flat plate shape as shown in FIG. The shape of the evaporator 110 may vary depending on the type of heat source providing the heat.

The heat dissipating portion 120 has an inlet end 122 and an outlet end 124.

The inlet end 122 is connected to the evaporator 110 and is a passage through which the heat exchange fluid evaporated in the evaporator 110 flows.

The outlet end 124 is connected to the evaporator 110 and is a passage through which the heat exchanging fluid condensed in the heat discharging unit 120 is discharged.

The heat dissipating unit 120 condenses the gaseous heat exchange fluid introduced through the inlet end 122 to discharge latent heat of condensation. It is preferable that the heat dissipating unit 120 has a zigzag shape to widen the contact area with the outside air.

The heat dissipating unit 120 may be disposed above the evaporator 110. Therefore, the heat exchange fluid evaporated in the evaporator 110 can be easily introduced into the heat dissipating unit 120 through the inlet end 122 without a separate pump.

The heat dissipating unit 120 may have a reduced cross-sectional area from the inlet end 122 to the outlet end 124. [ That is, since the cross-sectional area of the inlet end 122 is larger than the cross-sectional area of the outlet end 124, the heat exchange fluid evaporated in the evaporator 110 and having a large volume can be easily transferred to the inlet end 122, Lt; / RTI >

The pressure of the inlet end 122 is higher than the pressure of the outlet end 124 since the heat dissipating part 120 decreases in cross sectional area from the inlet end 122 to the outlet end 124. [ Therefore, the vaporized heat exchange fluid moves from the inlet end 122 to the outlet end 124 due to the pressure difference between the inlet end 122 and the outlet end 124.

The heat exchanging fluid that has been condensed while moving from the inlet end 122 to the outlet end 124 of the heat dissipating unit 120 can be supplied to the evaporator 110 through the outlet end 124 in a liquid state by gravity.

Therefore, the heat exchange fluid is evaporated in the evaporator 110 and then flows into the heat dissipating unit 120 through the inlet end 122 having a relatively large cross-sectional area. The evaporated heat-exchanging fluid passes through the inlet end 122 and the outlet end 122, (122) to the outlet end (124) due to the pressure difference between the inlet end (122) and the outlet end (124), and the condensed heat exchange fluid as it moves from the inlet end (122) And then flows into the evaporator 110 through the outlet end 124. Therefore, in the heat pipe 100, the heat exchange fluid can easily circulate between the evaporator 110 and the heat dissipating unit 120 while changing state.

Meanwhile, the evaporator 110 and the heat sink 120 have a closed curve shape. The shape of the heat pipe 100 can be variously changed by extending or bending the heat dissipating unit 120 under the condition that the heat dissipating unit 120 is located above the evaporator 110. [ Accordingly, since the heat pipe 100 can be mounted at various positions, utilization of the heat pipe 100 can be enhanced.

The heat pipe 100 according to the present invention circulates the heat exchange fluid between the evaporator 110 and the heat dissipation unit 120 due to pressure difference and gravity, A separate wick for moving to the evaporator 110 and a power source such as the pump are unnecessary.

As described above, in the heat pipe according to the present invention, the heat exchange fluid circulates between the evaporation portion and the heat dissipation portion due to pressure difference and gravity. Therefore, a separate power source such as a wick and a pump for moving the heat exchange fluid from the heat radiating portion to the evaporator portion by capillary action is unnecessary.

In addition, since the heat pipe has a closed curve shape, the heat pipe can be variously shaped by extending or bending the heat pipe. Therefore, the utilization of the heat pipe can be improved by mounting the heat pipe at various positions.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.
