Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, some structures and components that are conventional in the art are shown in simplified schematic form in the drawings.
Fig. 1 illustrates a perspective view of a projector module 200 according to an embodiment of the invention. Fig. 2 is a side view of the projector module 200 of fig. 1 with the blower 120 and the air guide 140 removed. Referring to fig. 1 and 2, the projector module 200 includes a rotary heat source 210 and a heat sink assembly 100. The heat sink assembly 100 may be used to cool the rotary heat source 210. The heat dissipation assembly 100 includes a housing 110, a blower 120, and a heat dissipation module 130. The housing 110 has an accommodating space 112, a first opening 114 and a second opening 116. The first opening 114 and the second opening 116 are communicated with the accommodating space 112, and the first opening 114 and the second opening 116 are located at different horizontal positions. In the present embodiment, the position of the second opening 116 in the housing 110 is higher than the position of the first opening 114 in the housing 110. The rotary heat source 210 is located in the accommodating space 112 of the housing 110. The first opening 114 of the housing 110 faces at least a portion of the rotary heat source 210. The blower 120 is located on an outer surface of the housing 110. The blower 120 has an air outlet 122 and an air inlet 124. The air outlet 122 of the blower 120 communicates with the first opening 114 of the housing 110, and the air inlet 124 of the blower 120 communicates with the second opening 116 of the housing 110, so that the accommodating space 112 is closed by the blower 120. In the present embodiment, the direction D1 of the air inlet 124 of the blower 120 is perpendicular to the axial direction D2 of the rotary heat source 210, but is not intended to limit the present invention.
The heat dissipation module 130 has a first portion 131 and a second portion 136 that are physically connected. The first portion 131 of the heat dissipation module 130 is located in the accommodating space 112 of the housing 110, and the second portion 136 of the heat dissipation module 130 is located outside the housing 110. That is, the heat dissipation module 130 passes through the housing 110 from the accommodating space 112 of the housing 110 and extends to the outside of the housing 110.
When the projector operates, the rotary heat source 210 can rotate in the accommodating space 112 of the housing 110 and receive light, so that the temperature of the rotary heat source 210 is increased. The rotary heat source 210 may be a fluorescent wheel (phosphor wheel), a diffusion wheel (diffuser wheel) or a color wheel (color wheel), but is not limited thereto. The rotary heat source 210 may include a disk 212 and a motor 214, wherein the motor 214 rotates the disk 212. When the rotary heat source 210 is a fluorescent wheel irradiated with laser light, the disk 212 may have transparent regions and phosphor regions.
Fig. 3 is a schematic diagram of the projector module 200 of fig. 1 in use. Referring to fig. 1 and 3, when the projector module 200 is in operation, the blower 120 is turned on, and the rotary heat source 210 rotates and is irradiated by light. The blower 120 flows out of the air flow F1 from the air outlet 122, and the air flow F1 flows into the accommodating space 112 through the first opening 114 (see also fig. 2) of the housing 110. Since the air outlet 122 of the blower 120 flows out of the air flow F1, the air inlet 124 of the blower 120 is also simultaneously drawn, and therefore the air flow F1 formed by the blower 120 flows through the rotary heat source 210 and the first portion 131 of the heat dissipation module 130, and then flows out of the second opening 116 (see also fig. 2) of the housing 110 and flows into the air inlet 124 of the blower 120. The air flow F1 can be repeatedly circulated in the closed accommodating space 112 as long as the blower 120 is continuously operated.
In this way, the heat of the rotary heat source 210 can be taken away by the airflow F1 generated by the blower 120, and the high-temperature airflow F1 passing through the rotary heat source 210 can be cooled by the first portion 131 of the heat dissipation module 130, so that the low-temperature airflow F1 returns to the blower 120 and is blown to the rotary heat source 210 by the blower 120 again. By the above-mentioned airflow circulation, not only dust can be prevented from entering the housing 110, but also the temperature of the rotary heat source 210 can be effectively reduced. The heat sink assembly 100 of the present invention can lower the temperature of the disk 212 of the rotary heat source 210 to within 200 ℃ and the temperature of the motor 214 to within 85 ℃.
In the present embodiment, the overall shape of the heat dissipation module 130 is U-shaped in plan view, but in other embodiments, the heat dissipation module may be linear, and is not intended to limit the present invention. The heat dissipation module 130 has a tube 135 passing through the housing 110, and the tube 135 has a working fluid therein, which may be a heat pipe or a water pipe, according to the needs of the designer. In the following description, the heat pipe 135 will be described as an example. The first portion 131 of the heat dissipation module 130 includes a heat pipe 135 and a first heat sink 132 in the accommodating space 112. The first heat sink 132 is disposed on the heat pipe 135 in the accommodating space 112. In addition, the second portion 136 of the heat dissipation module 130 includes a heat pipe 135 and a second heat sink 137 outside the accommodating space 112. The second heat sink 137 is located on the heat pipe 135 outside the case 110. The second portion 136 of the heat dissipation module 130 may further include a fan 138 and a cooling fin 139. The fan 138 is disposed on the second heat sink 137, and can form an airflow blowing toward the second heat sink 137, so as to improve the heat dissipation efficiency of the second portion 136 of the heat dissipation module 130, and further effectively reduce the temperatures of the accommodating space 112 and the rotary heat source 210. The cooling sheet 139 is located on the heat pipe 135 outside the accommodating space 112. The cooling fin 139 may maintain the temperature of the first heat sink 132 of the first portion 131 of the heat dissipation module 130 at a low temperature state through the heat pipe 135.
In other embodiments, the heat pipes 135 of the heat dissipation module 130 may be replaced by water pipes of a water cooling system, and the invention is not limited thereto.
In the present embodiment, the heat dissipation assembly 100 may further include an air guide 140. The air guide 140 is located between the first opening 114 (see also fig. 2) of the housing 110 and the air outlet 122 of the blower 120. When the direction of the air outlet 122 of the air guide 140 is different from the direction of the first opening 114 of the housing 110, the hollow air guide 140 can be used to communicate the air outlet 122 of the air guide 140 with the first opening 114 of the housing 110.
In addition, the number of the housing 110 may be determined by the designer's requirement, and is not intended to limit the present invention. For example, for the convenience of assembly, the housing 110 may also be formed by two or more sub-housings that are fastened, engaged or adhered to each other to form the accommodating space 112.
In the present embodiment, the first portion 131 of the heat dissipation module 130 is located higher than the rotary heat source 210, and the first portion 131 of the heat dissipation module 130 at least partially overlaps the rotary heat source 210. The position of the air inlet 124 of the blower 120 is substantially the same as the position of the second opening 116 (see also fig. 2) of the housing 110, and is also higher than the position of the rotary heat source 210. In addition, the second opening 116 of the housing 110 faces the first portion 131 of the heat dissipation module 130. With such a design, it is ensured that the airflow F1 entering the first opening 114 can pass through the rotary heat source 210 below the first portion 131 of the heat dissipation module 130 first, and after taking away heat from the rotary heat source 210, the airflow F1 passes through the first portion 131 of the heat dissipation module 130 upward or leftward, so that the airflow F1 is cooled and then is drawn back through the air inlet 124 of the blower 120.
It should be understood that the connection relationship between the components already described will not be repeated and will be described in the first place. In the following description, other types of heat dissipation components for projectors will be described.
Fig. 4 is a perspective view of a projector module 200a according to an embodiment of the invention. Fig. 5 is a perspective view of the projector module 200a of fig. 4 with the blower 120 removed. Referring to fig. 4 and 5, the projector module 200a includes a rotary heat source 210 and a heat sink 100 a. The heat dissipation assembly 100a includes a housing 110, a blower 120, and a heat dissipation module 130. The blower 120 is located on an outer surface of the housing 110. The blower 120 has an air outlet 122 and an air inlet 124. The air outlet 122 of the blower 120 communicates with the first opening 114 of the housing 110, and the air inlet 124 of the blower 120 communicates with the second opening 116 of the housing 110, so that the accommodating space 112 is closed by the blower 120. The difference from the embodiment of fig. 1 is that: the second opening 116 of the housing 110 is lower in the position of the housing 110 than the first opening 114 is in the position of the housing 110, and the direction D3 of the air inlet 124 of the blower 120 is parallel to the axial direction D4 of the rotary heat source 210.
Fig. 6 is a schematic diagram of the projector module 200a of fig. 4 in use. Referring to fig. 4 and 6, when the projector module 200a is in operation, the blower 120 is turned on, and the rotary heat source 210 rotates and is irradiated by light. The blower 120 flows out of the air flow F2 from the air outlet 122, and the air flow F2 flows into the accommodating space 112 through the first opening 114 (see also fig. 5) of the housing 110. Since the air outlet 122 of the blower 120 flows out of the air flow F2, the air inlet 124 of the blower 120 is simultaneously drawn, and therefore the air flow F2 formed by the blower 120 flows through the rotary heat source 210 and the first portion 131 of the heat dissipation module 130, and then flows out of the second opening 116 (see also fig. 5) of the housing 110 and flows into the air inlet 124 of the blower 120.
In the present embodiment, the casing 110 further includes an air guide portion 118. The air guide portion 118 is located between the first opening 114 of the casing 110 and the rotary heat source 210. The two ends of the air guiding portion 118 respectively have a first opening 114 and a third opening 119 communicating with the accommodating space 112, and the third opening 119 faces at least a part of the rotary heat source 210. For example, the third opening 119 may be located above the rotary heat source 210. The air guide portion 118 may receive the air flow F2 flowing out from the air outlet 122 of the blower 120 and guide the air flow F2 to the rotary heat source 210. The air guiding portion 118 may be a component added to the casing 110, or may be a part of the casing 110 structure, and is not limited in the invention.
In this way, the air flow F2 flowing out of the third opening 119 of the air guiding portion 118 carries away the heat of the rotary heat source 210, and the high-temperature air flow F2 passing through the rotary heat source 210 can be cooled by the first portion 131 of the heat dissipation module 130, so that the low-temperature air flow F2 returns to the blower 120 and is blown to the rotary heat source 210 by the blower 120 again.
In the present embodiment, the first portion 131 of the heat sink module 130 and the rotary heat source 210 do not overlap with each other and are separated by a distance. The second opening 116 (see also fig. 5) of the housing 110 is adjacent to the first portion 131 of the thermal module 130. The air flow F2 may flow into the accommodating space 112 near the rotary heat source 210 only when the air guiding portion 118 reaches the position of the third opening 119. Such a design is more flexible for the position design of the air outlet 122 and the air inlet 124 of the blower 120 and the first opening 114 and the second opening 116 of the housing 110. In addition, the heat dissipating assembly 100a can ensure that the airflow F2 entering the first opening 114 can pass through the rotary heat source 210 on the left of the first portion 131 of the heat dissipating module 130 first, and after taking away heat from the rotary heat source 210, the airflow F2 passes through the first portion 131 of the heat dissipating module 130 to the right, so that the airflow F2 is cooled and then is drawn back through the air inlet 124 of the blower 120.
Fig. 7 illustrates a cross-sectional view of the blower 120 and the housing 110 according to an embodiment of the present invention. The heat sink assembly 100a of fig. 4 may further include a dust cover 150. The dust boot 150 covers the blower 120 and at least a portion of the housing 110. When the dust cover 150 covers the outer surface of the blower 120 and the outer surface of the housing 110 adjacent to the blower 120, the air flow F2 is prevented from flowing out from the gap between the blower 120 and the housing 110. The material of the dust cover 150 may be rubber or foam, and is not intended to limit the present invention.
Similarly, the dust cover 150 can also be applied to the heat dissipation assembly 100 of fig. 1 to prevent the airflow F1 (see fig. 3) from flowing out from the gap between the blower 120 and the housing 110.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention, and it is intended that all such changes and modifications be included within the scope of the appended claims.
