Description

Pipe type two-phase flow radiator

This creation is about a radiator, especially a pipeline type two-phase flow radiator.

Due to the rapid development and application of communication equipment, the requirements for heat dissipation of equipment are becoming more and more strict. However, traditional fin-type heat sinks have been difficult to meet the heat dissipation requirements in a limited space. To solve such heat dissipation problems, fan forced convection is often used, or Water is cold.  However, the forced convection of the fan requires sufficient cooling space to install the fan and consumes electric energy. Although the water cooling effect is good, it requires a large cooling device to be placed and the cost is high.  Therefore, how to solve the above problems is the direction that researchers in the field must work hard.  

One of the purposes of this creation is to achieve a uniform distribution of heat at the pedestal and maximize the use of heat dissipation fins.  In order to achieve the above object, the present invention provides a pipeline type two-phase flow heat sink, comprising: a base having an upper side and a lower side, the upper side being provided with a plurality of fins; and a tube body Embedded in the lower side, the tube body has a first side, a second side and a liquid storage chamber communicating with at least one condensation end through at least one connecting portion, the second side of the tube body and the bottom of the base body The sides are flush.  According to the design of the present invention, the liquid storage chamber can store more working fluid, and the heat absorption region provided with the liquid storage chamber is attached to a heat source, so that a large amount of working fluid can quickly absorb heat and The heat is transferred to the condensation end, so that the heat of the heat source is not concentrated in the heat absorption zone, thereby achieving uniform heat distribution at the base and maximizing the heat dissipation function of the heat dissipation fins.

In the cross-sectional view, as shown in the figure, the pipeline type two-phase flow radiator of the present invention comprises a base 1 and a pipe body 2.  The base 1 has an upper side surface 11 and a lower side surface 12, and the upper side surface 11 is provided with a plurality of heat dissipation fins 13.  The tube body 2 is embedded in the lower side 12, and the tube body 2 has a first side 21, a second side 22, a liquid storage chamber 23, at least one connecting portion 24, at least one condensation end 25, And a degassing infusion tube 26.  In this embodiment, the lower side 12 of the base 1 is provided with a recess 14 , and the tubular body 2 can be accommodated in the recess 14 in any manner of tight fitting, welding, fitting and gluing.

In the present embodiment, the plurality of connecting portions 24 are connected to the plurality of condensation ends 25 In other embodiments, a connection portion 24 may be connected to a condensation end 25, which is not limited.  The liquid storage chamber 23 is correspondingly disposed in the heat absorption area 143, and is disposed adjacent to the heat absorption area 143. The condensation end 25 is correspondingly disposed in the condensation area 144 and is attached to the condensation area 144; the tube body 2 The first side 21 of the tube body 2 is attached to the closed side 142, the second side 22 of the tube body 2 is opposite to the open side 141, and the second side 22 of the tube body 2 and the lower side 12 of the base 1 are flush (eg Figure 4).  The deaeration infusion tube 26 is connected to and communicates with the liquid storage chamber 23 for extracting non-condensing gas inside the liquid storage chamber 23 and evacuating, and for inputting a working fluid. (not shown), the working fluid is selected to be any one of a gas phase fluid and a gas-liquid two phase change fluid.  In the present embodiment, the heat absorption zone 143 is located on one side 121 of the lower side 12, and the condensation zone 144 extends toward the other side 122 of the lower side 12.  With the design of the present invention, since the liquid storage chamber 23 is disposed, more working fluid can be stored, and the heat absorption region 143 provided with the liquid storage chamber 23 is attached to a heat source (not shown). The large amount of working fluid can quickly absorb heat and transfer the heat to the condensation end 25, so that the heat of the heat source is not concentrated in the heat absorption zone 143, thereby achieving uniform distribution of heat in the base 1 and maximizing the utilization of the heat dissipation fins 13 Cooling function.  Please refer to FIG. 6 , which is a three-dimensional combination diagram of the second embodiment of the pipeline type two-phase flow heat sink, and is supplemented with reference to FIGS. 1 to 5 , as shown in the figure, part of the structure and function of the embodiment. It is the same as the first embodiment described above, and therefore will not be described again here. However, the difference between the embodiment and the first embodiment is that the heat absorbing zone 143 is located at a central position 123 of the lower side 12, which is The condensing zone 144 extends toward the side edges 121, 122 of the lower side 12, and the tubular body 2 defines a plurality of connecting portions 24 and a plurality of condensing ends 25 corresponding to the shape and number of the condensing zones 144.  In an alternate embodiment, referring to Figure 7, the condensing zone 144 extends toward the periphery of the central location 123.  Please refer to FIG. 8 , which is a sectional view of the third embodiment of the pipeline type two-phase flow heat sink, and is supplemented with reference to FIGS. 1 to 7 .

There is a capillary structure 28, which is selected as a sintered body, a mesh body, a fiber body, a braid or a groove or a combination thereof. When the working fluid filled in the pipe body 2 is a gas-liquid two-phase changing fluid, The working fluid diffuses in the liquid storage chamber 23 and evaporates toward the condensation end 25, and condenses to a liquid state at the condensation end 25, and the capillary fluid of the capillary structure 28 rapidly returns the liquid working fluid of the condensation end 25 to the liquid. The liquid storage chamber 23 reduces the probability of dry burning inside the liquid storage chamber 23.  The present invention has been described in detail above, but the above description is only a preferred embodiment of the present invention, and the scope of the present invention cannot be limited.
