Small heat pipe occupied thickness space in electronic equipment is conducive to reduce the thickness of electronic equipment, is allowed to realize lightening.
Further, in above-mentioned heat pipe, heat eliminating medium is set as liquid heat eliminating medium.In application, liquid heat eliminating medium exists
It constantly during flowing, absorbs the heat of heat source electronic component 201 and makes the heat loss, in entire heat absorption and radiation processes
Liquid is remained, the middle heat pipe that heat absorption and heat dissipation are realized using heat eliminating medium phase transformation, is not present compared with the prior art
The problem of caloric receptivity reaches the upper limit in endothermic process it can quickly and efficiently absorb the heat of the heat dissipation of heat source electronic component 201 simultaneously
It is allowed to lost, radiating efficiency higher, effect is more preferable.
Further, in above-mentioned heat pipe, heat eliminating medium is configured to that phase does not occur in the first preset temperature range
Become, remains liquid.It is well known that the thermal Finite that the heat source electronic component 201 of electronic equipment generates, and in the present embodiment
Heat eliminating medium is configured to keep liquid in the first preset temperature range, can always be protected during electronic apparatus application
Hold liquid with to heat source electronic component 201 effectively radiate, be also convenient for expand heat eliminating medium selection range, facilitate user according at
Sheet, manufacture craft etc. choose suitable material and do heat eliminating medium.Specifically, above-mentioned first preset temperature range be set as -20 ° -
100°。
In addition, in above-mentioned heat pipe, 101 internal fluid passageways of shell may be configured as being full of by heat eliminating medium, but shell 101 needs
It encapsulates, in order to reduce manufacture difficulty, the heat eliminating medium that the internal fluid passageways of shell 101 are set as existing liquid has gas again
Body.Since the thickness of above-mentioned shell 101 is smaller, in order to avoid liquid heat eliminating medium is made in 101 internal cause surface tension of shell
With and generate bubble or even form discontinuous heat eliminating medium liquid bead, above-mentioned shell 101 is set as inner wall and is soaked with heat eliminating medium
The shell 101 of profit, to ensure that heat eliminating medium can form stable and liaison liquid heat eliminating medium stream in shell 101, it is ensured that
The heat pipe always can effectively radiate to heat source electronic component 201.
Correspondingly, the material preparation infiltrated with the heat eliminating medium of liquid can be used in above-mentioned shell 101, it can also be in shell 101
Inner wall be arranged soakage layer.Specifically, according to the type of heat eliminating medium, above-mentioned soakage layer may be configured as plastic coating, nickel coating
Or the electroplated layer etc. that other metals are formed.
For the ease of manufacture and it is cost-effective, above-mentioned shell 101 may be configured as inner wall equipped with nickel coating copper pipe or
Person's inner wall is equipped with the aluminum pipe of nickel coating, and certainly according to the infiltration needs of heat eliminating medium, shell 101 may also be configured to by other materials
The shell 101 of preparation, or the shell 101 with other soakage layers, the present embodiment is not specifically limited.
In above-mentioned heat pipe, heat eliminating medium is set as liquid metal heat radiation medium, which can specifically set
It is set to gallium-indium alloy heat eliminating medium or sodium-potassium eutectic heat eliminating medium.
Specifically, in above-mentioned heat pipe, another group of opposite the distance between the internal face of side wall is not more than in shell 101
L2 need to be set as being not more than 25mm in 25mm, i.e., such as Fig. 2-5.Above-mentioned shell 101 may be configured as the rectangle shell of rule, such as Fig. 3
It is shown, rectangle shell of the edge with chamfering is may also be configured to, as shown in Fig. 2, it is other types four to be set as cross section
Side shape, other shells close to quadrangle, as illustrated in figures 4-5.
The shell 101 of above-mentioned heat pipe is set as annular enclosed shell, and shell 101 is equipped with actuator 102, scattered for driving
Thermal medium constantly does annularly flow along shell 101.In order to coordinate liquid metal heat radiation medium, above-mentioned actuator 102 that can specifically set
It is set to electromagnetic pump.
In the heat pipe, heat eliminating medium is driven by actuator 102, middle compared to the prior art to utilize phase-change heat medium and hair
Fine texture is not influenced the heat pipe of heat source electronic element radiating by heat eliminating medium gravity, can make heat eliminating medium quickly by
Bulb portion on shell 101 for heat dissipation flows back to bulb portion corresponding with heat source electronic component 201, makes heat source electronic component
201 heat can quickly scatter and disappear, radiating efficiency higher.
The present invention also provides a kind of electronic equipment comprising heat source electronic component 201 and for heat source electronic component 201
The heat pipe of heat dissipation, wherein heat pipe is the heat pipe that above-described embodiment provides.
Above-mentioned heat pipe cooperation radiator fan 202 is used to radiate to heat source electronic component 201.Last point of heat pipe with
Heat source electronic component 201 overlaps, and another part is close to radiator fan 202, in application, heat eliminating medium is first with heat source electronics
Heat is absorbed at 201 corresponding position of part, is then passed at position corresponding with radiator fan 202 and in radiator fan 202
The lower heat dissipation of effect, heat eliminating medium flow to part corresponding with heat source electronic component 201 and absorbs heat again later, and so on, real
Now radiate to heat source electronic component 201.
The heat pipe that electronic apparatus application provided by the invention above-described embodiment provides, thickness can be set as compared with
It is small, conducive to meeting the needs of user is lightening to electronic equipment.Certainly, which also has with what above-described embodiment provided
