Description

projector

[0001] The present disclosure relates to a projector.

[0002] A projector is an optical device used to magnify and project images, videos, text, etc., onto a screen through a lens.

[0003] With the advancement of technology enabling high-definition displays, not only the previously widely used direct-view type display devices but also large-screen projection TVs, PDP TVs, and projectors are gaining popularity as display devices.

[0004] In particular, projectors have the advantage of being able to create large screens compared to other display devices, so their use is gradually expanding to include home display devices, in addition to their traditional use as display devices for personal computers for business purposes such as seminar presentations.

[0005] Recently, as the applications of projectors have expanded, they are being used not only indoors but also outdoors, leading to a rising demand for portable projectors. However, as the image quality and performance of projectors improve, the amount of heat generated increases, necessitating a heat dissipation structure capable of effectively dissipating this heat. Consequently, as the size of the heat dissipation unit required to construct a structure capable of dissipating a large amount of heat grows, the overall size of the projector product also increases. Therefore, structural improvements to the heat dissipation system are required to enable the miniaturization of projectors.

[0006] The heat dissipation unit may include a heat sink. The heat sink can form a relatively large heat transfer surface area by having a base plate and a plurality of fin structures. Accordingly, the heat sink can effectively dissipate heat received from an external heat source.

[0007] One aspect of the present disclosure provides a projector with an improved heat dissipation structure.

[0008] One aspect of the present disclosure provides a projector configured to apply various cooling flows to a single heat dissipation section.

[0009] One aspect of the present disclosure provides an improved heat sink.

[0056] A second fan (42) may be positioned near the intake section (12) of the housing (10). As the second fan (42) operates in a suction and blowing manner near the intake section (12), it can create additional airflow inside the housing (10).

[0057] Specifically, the second fan (42) may be positioned near the first heating element (101) and the second heating element (102). Accordingly, the second fan (42) may be provided to provide additional airflow to the first heating element (101) and the second heating element (102) to increase the cooling efficiency of the first heating element (101) and the second heating element (102).

[0058] The second fan (42) can be provided to form an air flow (80) inside the housing (10) through a blowing method. The second fan (42) can be provided to more strongly suck in air flowing into the intake section (12) through an intake method and blow air into the housing (10) through a blowing method to strengthen the internal air flow (80). In other words, the second fan (42) can be provided to form a second air flow (82).

[0059] The outside air fan (43) may be located in the center of the housing (10). Specifically, the outside air fan (43) may be positioned near the central heating element (103). The outside air fan (43) may be provided at the outside air outlet (71) of the outside air duct (70) to be described later. Accordingly, the outside air fan (43) may be provided so that the central heating element (103) is directly cooled by the outside air introduced through the outside air duct (70). A detailed description of the structure of the outside air duct (70) will be provided later in the following drawings.

[0060] The projector (1) may include a heat sink (200). The number of heat sinks (200) may be multiple. The heat sink (200) may be provided to receive heat from the heat source (100).

[0061] A single heat sink (200) may be configured to dissipate heat by a plurality of fans (40). In other words, a plurality of air flows (80) may pass through the heat sink (200) and the heat sink (200) may be configured to dissipate heat. A detailed description of the heat dissipation of a single heat sink (200) through a plurality of air flows (80) will be provided later in the following drawings.

[0062] The first heat sink (201) may be provided to receive heat from the first heating element (101). The second heat sink (202) may be provided to receive heat from the second heating element (102). The first heat sink (201) and the second heat sink (202) may be provided spaced apart from each other on both sides of the light source assembly (50).

A detailed description of the arrangement of the fan (40) and the heat sink (200) and various embodiments of the heat sink (200) will be provided later in the other drawings below.

[0066] The first heating element (101) of the light source assembly (50) may be placed on one side of the light source assembly (50), and the second heating element (102) may be placed on a different side from the first heating element (101). By placing the first heating element (101) and the second heating element (102) on different sides of the light source assembly (50), the volume of the light source assembly (50) can be prevented from increasing. The light source assembly (50) can emit the most heat inside the housing (10).

[0067] The first heating element (101) and the second heating element (102) may be high heating elements. Accordingly, a plurality of heat sinks (200) for dissipating heat from each may be provided. However, this is not limited thereto, and the first heating element (101) and the second heating element (102) may be provided to dissipate heat through a single heat sink (200). Various embodiments of the heat sink (200) that increase the heat dissipation efficiency of the heating element (100) will be described later in other drawings below.

[0068] FIG. 3 is a cross-sectional view taken along A-A' in FIG. 2 of a projector according to one embodiment of the present disclosure. FIG. 4 is a cross-sectional view taken along B-B' in FIG. 2 of a projector according to one embodiment of the present disclosure.

[0069] In the following description, for the convenience of explanation, substantially identical or similar configurations to those described with reference to FIG. 1 and FIG. 2 may be omitted or briefly described.

[0070] Referring to FIGS. 3 and 4, the projector (1) can accommodate a plurality of fans (40) inside the housing (10). Each of the plurality of fans (40) can be positioned at various locations inside the housing (10). Accordingly, various internal air flows (80) can be formed inside the housing (10).

[0071] For example, the internal air flow (80) may include a first air flow (81) formed by a first fan (41), a second air flow (82) formed by a second fan (42), and an external air flow (83) formed by an external fan (43).

[0072] The projector (1) may be configured such that a single heat sink (200) dissipates heat through a plurality of internal air flows (80). The projector (1) may include a plurality of heat sinks (200).

[0073] For example, the first heat sink (201) may be configured to dissipate heat by the first air flow (81) and the second air flow (82). The first heat sink (201) may include a plurality of heat dissipation fins (210).

[0074] The second fan (42) may be provided adjacent to the heat dissipation fin (210) coupled to the first heat sink (201). The heat dissipation fin (210) of the first heat sink (201) may be provided to have a higher height than the adjacent second fan (42). Accordingly, the heat dissipation fin (210) of the first heat sink (210) may have a protrusion (210a) in an area higher than the second fan (42) and a corresponding part (210b) in an area lower than the second fan (42). In other words, the heat dissipation fin (210) of the first heat sink (201) may include a protrusion (210a) that protrudes outward from the edge of the second fan (42) and a corresponding part (210b) provided to correspond to the inner side of the edge of the second fan (42).

[0075] The second fan (42) can be configured so that the second air flow (82) passes through the first heat sink (201). Accordingly, the second air flow (82) can be configured to pass through the corresponding portion (210b) of the heat dissipation fin (210) of the first heat sink (210).

[0076] The first fan (41) can be configured so that the first air flow (81) passes through the first heat sink (201). Accordingly, the first air flow (81) can be configured to pass through the protrusion (210a) of the heat dissipation fin (210) of the first heat sink (201).

[0077] The second fan (42) may be provided adjacent to the heat dissipation fin (210) coupled to the second heat sink (202). The heat dissipation fin (210) of the second heat sink (202) may be provided to have a higher height than the adjacent second fan (42). Accordingly, the heat dissipation fin (210) of the second heat sink (202) may have a protrusion (210a) in an area higher than the second fan (42) and a corresponding part (210b) in an area lower than the second fan (42). In other words, the heat dissipation fin (210) of the second heat sink (202) may include a protrusion (210a) that protrudes outward from the edge of the second fan (42) and a corresponding part (210b) that is provided to correspond to the inner side of the edge of the second fan (42).

[0078] The second fan (42) can be configured so that the second air flow (82) passes through the second heat sink (202). Accordingly, the second air flow (82) can be configured to pass through the corresponding portion (210b) of the heat dissipation fin (210) of the second heat sink (202).

[0079] The first fan (41) can be configured so that the first airflow (81) passes through the second heat sink (202). Accordingly, the first airflow (81) can be configured to pass through the protrusion (210a) of the heat dissipation fin (210) of the second heat sink (202).

[0080] In other words, the second fan (42) is positioned adjacent to the first heat sink (201) and the second heat sink (202) to form a second airflow (82) that strongly passes through the first heat sink (201) and the second heat sink (202). The first fan (41) is positioned spaced apart from the first heat sink (201) and the second heat sink (202) to form a first airflow (81) that passes through an area where the second airflow (82) is not formed in the first heat sink (201) and the second heat sink (202).

[0081] The projector (1) may include an outside air duct (70) positioned below the second heat sink (202).

[0082] The outside air duct (70) may include an outside air inlet (72), an outside air outlet (71), and a partition plate (75).

[0083] An external air inlet (72) may be provided on one side of the intake section (12) of the housing (10). External air may be introduced into the housing (10) of the projector (1) through the external air inlet (72) formed on one side of the intake section (12).

[0084] An outside air outlet (71) may be formed on the central side of the housing (10). The outside air outlet (71) may be provided near the central heat sink (203). Accordingly, the outside air duct (70) may be provided to open toward the central heat sink (203).

[0085] An outside air fan (43) may be provided on one side of the outside air outlet (71). The outside air fan (43) may be positioned between the outside air outlet (71) and the central heat sink (203). The outside air fan (43) may be configured to suck in the outside air flow (83) entering through the outside air outlet (71) and blow it toward the central heat sink (203).

[0086] The partition plate (75) may be provided to connect the outside air inlet (72) and the outside air outlet (71). The partition plate (75) may form the upper surface of the outside air duct (70). The partition plate (75) may be provided so that the outside air flow (83) formed to pass through the outside air duct (70) is separated from the first air flow (81) and the second air flow (82) that have passed through the second heat sink (202).

[0087] In other words, the outside air duct (70) can be configured so that outside air not heated by the second heat sink (202) directly cools the central heat sink (203). In other words, the outside air flow (83) passing through the outside air duct (70) can be configured to bypass the second heat sink (202).

[0088] Accordingly, the central heat sink (203) can be arranged to dissipate heat through the unheated external air flow (83) passing through the second heat sink (202). Accordingly, the heat dissipation efficiency of the central heat sink (203) can be increased.

[0089] The partition plate (75) may include a flat section (76) and an inclined section (77). The flat section (76) may be provided to be connected to the outside air inlet (72) of the outside air duct (70). A second heat sink (202) and a second fan (42) may be installed on the upper side of the flat section (76).

[0090] The inclined section (77) may be provided between the flat section (76) and the outside air outlet (71). The inclined section (77) may be provided to be inclined upward as it moves from the outside air inlet (72) toward the outside air outlet (71). Accordingly, the area of ​​the outside air outlet (71) may be provided to be larger than the area of ​​the outside air inlet (72).

[0091] Accordingly, the outside air flow (83) passing through the outside air duct (70) can be arranged so that the central heat sink (203) dissipates heat over a wide area.

[0092] The inclined portion (77) can be provided so that the high-temperature internal air flow (80) heated while passing through the second heat sink (202) and the low-temperature external air flow (83) are not mixed. Before the internal air flow (80) passes through the center of the inner side of the housing (10), the first air flow (81) and the second air flow (82) can be provided so that they are separated from the external air flow (83) by the inclined portion (77) of the partition plate (75).

[0093] The first air flow (81) and the second air flow (82) may be arranged to flow upward along the inclined portion (77) and pass through the upper part of the central heat sink (203). The first air flow (81) and the second air flow (82) that have passed through the upper part of the heat sink (200) may be arranged to be guided to the outside by the first fan (41) through the exhaust portion (11) of the housing (10).

[0094] To prevent obstruction of the flow of internal air flow (80), including the first air flow (81) and the second air flow (82), the partition plate (75) may be provided at a predetermined distance from the upper surface (13) of the housing (10).

[0095] The outside air flow (83) can be guided to flow along the outside air duct (70) and pass through the central heat sink (203). The outside air flow (83) can be arranged to pass through the lower part of the central heat sink (203). As the area of ​​the outside air outlet (71) through which the outside air flow (83) passes is increased by the inclined portion (77) of the partition plate (75), the outside air flow (83) can be arranged to pass through a wider area of ​​the central heat sink (203).

[0096] Accordingly, the central heating element (103) can be configured to be cooled by a low-temperature external air flow (83) in addition to the relatively high-temperature first air flow (81) and second air flow (82).

[0097] FIG. 5 is an enlarged view of area C in FIG. 2 in a projector according to one embodiment of the present disclosure.

[0098] Referring to FIG. 5, the heat sink (200) may include a 3D vapor chamber (220) and heat dissipation fins (210).

[0099] According to one example, the 3D vapor chamber (220) may include a base plate (221) and a heat pipe (223) to disperse heat in three dimensions.

[0100] The 3D vapor chamber (220) may be arranged to be in contact with the heating element (100). The 3D vapor chamber (220) may be arranged to receive heat from the heating element (100). The 3D vapor chamber (220) may be arranged to transfer the heat received from the heating element (100) to the heat dissipation fins (210).

[0101] Specifically, the 3D vapor chamber (220) may include a base plate (221) provided in the shape of a thin plate and a heat pipe (223) formed protruding from one side of the base plate (221).

[0102] For example, the heat pipe (223) may be provided to protrude vertically from the base plate (221). However, the direction of protrusion of the heat pipe (223) is not limited to the vertical direction, and if necessary, the heat pipe (223) may be bent and provided to extend in a horizontal direction parallel to the base plate (221).

[0103] The heat pipes (223) may be provided in multiple numbers. The multiple heat pipes (223) may be provided spaced apart from each other.

[0104] The 3D vapor chamber (220) may have a storage space inside. A refrigerant (R) may be stored in the storage space. The refrigerant (R) is a medium capable of transferring heat by absorbing or releasing heat. The refrigerant (R) may flow inside the storage space.

[0105] The storage space may include a first storage space (222). The first storage space (222) may be provided inside the base plate (221). The first storage space (222) may extend along the direction in which the base plate (221) extends. Accordingly, the refrigerant (R) may flow along the first storage space (222) so as to distribute heat onto the plane of the base plate (221).

[0106] The storage space may include a second storage space (224). The second storage space (224) may be provided inside the heat pipe (223). Accordingly, the refrigerant (R) may flow along the second storage space (224) so ​​as to transfer heat along the length of the heat pipe (223). The second storage space (224) may extend along the direction in which the heat pipe (223) extends.

[0107] Accordingly, when the heat pipe (223) protrudes vertically from the base plate (221), the refrigerant (R) can be arranged to flow through the base plate (221) and the heat pipe (223) to enable heat transfer in three dimensions.

[0108] The second storage space (224) can be connected to the first storage space (222). In other words, the second storage space (224) can be connected to the first storage space (222). Through this configuration, the refrigerant (R) in the second storage space (224) can flow into the first storage space (222), and the refrigerant (R) in the first storage space (222) can flow into the second storage space (224).

[0109] As described above, the heat pipe (223) may be provided in multiple numbers. Accordingly, the second storage space (224) may also be provided in multiple numbers. The multiple second storage spaces (224) may be provided inside each of the multiple heat pipes (223).

[0110] The base plate (221) can receive heat from an external heat source. Accordingly, the refrigerant (R) stored in the first storage space (222) can evaporate. The refrigerant (R) evaporated in the first storage space (222) can flow to the second storage space (224) due to natural convection.

[0111] Since the heat pipe (223) is located farther from an external heat source than the base plate (221), the temperature around the heat pipe (223) can be lower than the temperature around the base plate (221).

[0112] Accordingly, the heat pipe (223) can transfer heat to the area around the heat pipe (223), and the refrigerant (R) stored in the second storage space (224) can condense. The condensed refrigerant (R) can flow into the first storage space (222).

[0113] That is, the 3D vapor chamber (220) can transfer heat through a refrigerant (R) that flows through a first storage space (222) in the base plate (221) and a second storage space (224) in the heat pipe (223) while undergoing a phase change.

[0114] Through this heat transfer method, the 3D vapor chamber (220) can transfer heat relatively faster. In addition, since a storage space where the refrigerant (R) can flow is provided not only inside the base plate (221) but also inside the heat pipe (223), the heat transfer efficiency in the two-dimensional horizontal direction inside the base plate (221) as well as the heat transfer efficiency in the three-dimensional vertical direction inside the heat pipe (223) can be relatively increased.

[0115] The first heat sink (201) may be provided to receive heat from the first heating element (101). The first heat sink (201) may be positioned to be in contact with the first heating element (101). The first heat sink (201) may be positioned in front of the light source assembly (50).

[0116] For example, the first heating element (101) may be provided on the front of the light source assembly (50). Accordingly, the base plate (221) of the first heat sink (201) may be provided to be in contact with the front of the light source assembly (50). The base plate (221) of the first heat sink (201) may be referred to as the first base plate.

[0117] The heat pipe (223) of the first heat sink (201) may be arranged to protrude vertically from the base plate (221). Accordingly, the heat dissipation fin (210) of the first heat sink (201) coupled to the heat pipe (223) may be positioned in front of the light source assembly (50).

[0118] The heat pipes (223) of the first heat sink (201) may be provided in multiple numbers. For example, the heat pipes (223) may be provided so as to be spaced apart from each other on the base plate (221). A heat dissipation fin (210) may be attached to each of the multiple heat pipes (223a, 223b) located on the left and right sides relative to the base plate (221).

[0119] Accordingly, the heat dissipation fin (210) connected to the left heat pipe (223a) and the heat dissipation fin (210) connected to the right heat pipe (223b) can be arranged to be spaced apart from each other.

[0120] The second fan (42) may be positioned between the heat dissipation fin (210) connected to the left heat pipe (223a) and the heat dissipation fin (210) connected to the right heat pipe (223b). Accordingly, the heat dissipation fin (210) connected to the left heat pipe (223a) may be arranged to dissipate heat through the second air flow (82) formed by the suction operation of the second fan (42).

[0121] Accordingly, the heat dissipation fin (210) coupled to the right heat pipe (223b) can be arranged to dissipate heat through the second air flow (82) formed by the blowing operation of the second fan (42).

[0122] The second heat sink (202) may be provided to receive heat from the second heating element (102). The second heat sink (202) may be positioned to be in contact with the second heating element (102).

[0123] For example, the second heating element (102) may be provided on the side of the light source assembly (50). Accordingly, the base plate (221) of the second heat sink (202) may be provided to be in contact with the side of the light source assembly (50). The base plate (221) of the second heat sink (202) may be referred to as the second base plate.

[0124] The heat pipe (223) of the second heat sink (202) may be arranged to be bent and extended when protruding from the base plate (221). In other words, the heat pipe (223) of the second heat sink (202) may be extended in a direction parallel to the base plate (221).

[0125] In other words, the heat pipe (223) of the second heat sink (202) can be arranged to protrude horizontally relative to the base plate (221).

[0126] For example, the heat pipe (223) of the second heat sink (202) may be arranged to extend outward toward the rear of the light source assembly (50). Accordingly, the heat dissipation fin (210) coupled to the heat pipe (223) may be positioned at the rear of the light source assembly (50).

[0127] A second fan (42) may be placed on one side of the heat dissipation fin (210) of the second heat sink (202).

[0128] As the heat pipe (223) is bent and extended backward from the base plate (221) that contacts the side of the light source assembly (50), the projector (1) can be prevented from expanding laterally even when the heating element (100) is located on the side of the light source assembly (50).

[0129] Accordingly, the projector (1) can be made smaller.

[0130] According to one example, a second fan (42) may be provided in the first heat sink (201) and the second heat sink (202), respectively. Specifically, in the first heat sink (201), the second fan (42) may be positioned between the heat dissipation fin (210) connected to the left heat pipe (223a) and the heat dissipation fin (210) connected to the right heat pipe (223b).

[0131] Additionally, the second fan (42) in the second heat sink (202) may be positioned on one side of the heat dissipation fin (210) of the second heat sink (202).

[0132] At this time, the second fan (42) can be located inside the housing (10) rather than the heat dissipation fin (210).

[0133] In other words, a heat dissipation fin (210) can be provided between the second fan (42) and the housing (10). That is, a heat dissipation fin (210) can be positioned between the second fan (42) and the intake part (12).

[0134] Accordingly, the second fan (42) can be arranged to be spaced apart from the intake part (12) of the housing (10) by a predetermined distance.

[0135] As the position of the second fan (42) moves away from the intake part (12) of the housing (10), there may be an effect of reducing the noise generated during the operation of the second fan (42).

[0136] Accordingly, under the same noise conditions, the second fan (42) can be driven more strongly than when the second fan (42) is in contact with the intake part (12) of the housing (10).

[0137] In other words, the cooling performance of the second fan (42) can be increased under the same noise conditions.

[0138] A detailed explanation regarding the degree of noise reduction and cooling performance according to the arrangement of the fan (40) will be described later in the following drawings.

[0139] FIG. 6 is a perspective view of a heat sink according to one embodiment of the present disclosure. FIG. 7 is a perspective view of a heat sink according to one embodiment of the present disclosure.

[0140] Referring to FIGS. 6 and 7, the shape and structure of the first heat sink (201) and the arrangement of the second fan (42) will be described. Meanwhile, if there is no need to distinguish between the plurality of heat sinks (200) and the plurality of fans (40) included in the projector (1), the description of the first heat sink (201) and the second fan (42) may be a description common to all of them.

[0141] In addition, for convenience of explanation, in the following description, configurations that are substantially identical or similar to those described with reference to FIG. 5 may be omitted or briefly described.

[0142] Referring to FIGS. 5 to 7, the first heat sink (201) may be provided with heat dissipation fins (210) in various shapes. For example, the heat dissipation fins (210) may be provided with a shape separated into left and right sides. Accordingly, the heat dissipation fins (210) may be provided to be connected to the left heat pipe (223a) and the right heat pipe (223b), respectively.

[0143] The heat dissipation fins (210) coupled to each heat pipe (223a, 223b) can be arranged so that a plurality of heat dissipation fins (210) are stacked and coupled along the extension direction of each heat pipe (223a, 223b).

[0144] The second fan (42) can be placed between the heat dissipation fin (210) connected to the left heat pipe (223a) of the first heat sink (201) and the heat dissipation fin (210) connected to the right heat pipe (223b).

[0145] Accordingly, the heat dissipation fin (210) connected to the left heat pipe (223a) relative to the second fan (42) can be located in the intake area of ​​the second fan (42). The heat dissipation fin (210) connected to the right heat pipe (223b) can be located in the blower area of ​​the second fan (42).

[0146] In the second air flow (82) formed by the second fan (42), the second air flow (82) in the blowing area may include turbulence formed by the second fan (42). Accordingly, when the second air flow (82) passes through the heat dissipation fin (210) in the blowing area, the amount of heat exchange may be increased as the contact between the heat dissipation fin (210) and the second air flow (82) is increased by the turbulence included in the second air flow (82).

[0147] Accordingly, in the second fan (42) operating at the same intensity, the heat dissipation efficiency of the heat dissipation fin (210) located in the blower area can be arranged to be greater than the heat dissipation efficiency of the heat dissipation fin (210) located in the intake area.

[0148] Meanwhile, as heat dissipation fins (210) are provided in the intake area of ​​the second fan (42) located near the intake section (12) of the projector (1), the noise level of the second fan (42) measured from the outside of the projector (1) can be reduced. In other words, heat dissipation fins (210) located between the second fan (42) and the housing (10) of the projector (1) can be provided to cushion the noise of the second fan (42). Additionally, the second fan (42) can be provided to be spaced apart from the housing (10) by the length of the heat dissipation fins (210).

[0149] Accordingly, as the heat dissipation fin (210) is positioned between the second fan (42) and the intake portion (12) of the housing (10), the second fan (42) can be operated more strongly under the same noise conditions. As the second fan (42) operates more strongly, the heat dissipation efficiency of the first heat sink (201) can be increased.

[0150] Meanwhile, referring to FIG. 7, the heat dissipation fin (210) of the first heat sink (201) may be provided in the shape of a single heat dissipation fin (210) that is not separated into left and right sides. A plurality of single heat dissipation fins (210) may be connected to the heat pipe (223) along the extension direction of the heat pipe (223).

[0151] The heat dissipation fins (210) may be placed in the intake area of ​​the second fan (42). Accordingly, the first heat sink (201) may be arranged to dissipate heat through the second air flow (82) formed by the intake operation of the second fan (42).

[0152] The second fan (42) can be provided to be spaced apart from the housing (10) by the length of the heat dissipation fin (210). As the heat dissipation fin (210) is provided as a single heat dissipation fin (210) rather than being separated into left and right sides, the distance between the second fan (42) and the housing (10) can be increased. Accordingly, the noise level of the second fan (42) can be reduced. Accordingly, the second fan (42) can be operated more strongly under the same noise conditions.

[0153] In an embodiment of the invention, a heat dissipation fin (210) is shown positioned between the second fan (42) and the housing (10) as an example, but the concept of the invention is not limited thereto. For example, the heat dissipation fin (210) may be arranged to be placed in the air blowing area of ​​the second fan (42).

[0154] Accordingly, the first heat sink (201) is configured to dissipate heat through the second air flow (82) formed by the blowing operation of the second fan (42), so that the heat dissipation efficiency of the first heat sink (201) can be increased.

[0155] In the embodiment of the invention, the first heat sink (201) was described as an example, but the described arrangement structure of the second fan (42) and heat dissipation fins (210) may also be a common description for the fan (40) and heat dissipation fins (210) in the second heat sink (202) and the central heat sink (203) in addition to the first heat sink (201).

[0156] FIG. 8 is a perspective view of a heat sink according to one embodiment of the present disclosure. FIG. 9 is a top view of the heat sink of FIG. 8 according to one embodiment of the present disclosure.

[0157] In the following description, for the convenience of explanation, substantially identical or similar configurations to those described with reference to FIG. 5 may be omitted or briefly described.

[0158] Referring to FIGS. 8 and 9, according to one embodiment of the present disclosure, a plurality of heat-generating parts (100) of a light source assembly (50) may be arranged to dissipate heat through a single heat sink (300).

[0159] For example, a plurality of heating elements (100) of the light source assembly (50) may be provided on the front and side of the light source assembly (50). Accordingly, the 3D vapor chamber (320) of the heat sink (300) may include a plurality of base plates (321a, 321b) that are provided to contact each of the plurality of heating elements (100).

[0160] Accordingly, the 3D vapor chamber (320) may include a first base plate (321a) in contact with a first heating element (101) provided on the front of the light source assembly (50) and a second base plate (321b) in contact with a second heating element (102) provided on the side of the light source assembly (50).

[0161] The 3D vapor chamber (320) may include a first heat pipe (323a) that extends vertically from one side of the first base plate (321a) and a second heat pipe (323b) that extends vertically from the other side of the first base plate (321a).

[0162] The other side of the first base plate (321a) may be the side where the first base plate (321a) and the first heating element (101) come into contact. Accordingly, the first heat pipe (323a) protruding from one side of the first base plate (321a) may be arranged to extend toward the front of the light source assembly (50).

[0163] Accordingly, the second heat pipe (323b) protruding from the other side of the first base plate (321a) can be arranged to extend toward the rear of the light source assembly (50).

[0164] A second base plate (321b) that contacts the second heating element (102) may be provided on one side of the second heat pipe (323b). Accordingly, heat generated from the second heating element (102) can be transferred to the first base plate (321a) through the second heat pipe (323b).

[0165] More specifically, the 3D vapor chamber (320) may be provided with an internal space in which a refrigerant (R) is stored inside each component. The internal spaces of each component of the 3D vapor chamber (320) may be provided to be connected to each other.

[0166] Specifically, the first base plate (321a) may be provided to be in communication with the first heat pipe (323a) and the second heat pipe (323b), respectively. Additionally, the second heat pipe (323b) may be provided to be in communication with the second base plate (321b).

[0167] Accordingly, the refrigerant (R) stored in the internal space of the 3D vapor chamber (320) can be arranged to transfer heat between the components as it moves into the internal space of each component.

[0168] A plurality of heat dissipation fins (210) may be connected to the 3D vapor chamber (320). The heat dissipation fins (210) may be connected to the first heat pipe (323a). The first heat pipe (323a) may be provided to pass through the heat dissipation fins (210).

[0169] The refrigerant (R) flowing through the internal space of the first heat pipe (323a) can transfer heat from the first base plate (321a) to the heat dissipation fins (210) coupled to the first heat pipe (323a).

[0170] That is, the heat sink (300) can be configured so that heat generated from the first heating part (101) and the second heating part (102) is transferred to the heat dissipation fin (210) after passing through the first base plate (321a) and the first heat pipe (323a) and then dissipated.

[0171] The heat sink (300) may be provided only in front of the light source assembly (50). Accordingly, the volume of the heat sink (300) is reduced, so the projector (1) can be miniaturized.

[0172] FIG. 10 is a perspective view of a heat sink according to one embodiment of the present disclosure. FIG. 11 is a cross-sectional view of D-D' in FIG. 10 of a projector according to one embodiment of the present disclosure.

[0173] In the following description, for the convenience of explanation, substantially identical or similar configurations to those described with reference to FIG. 5 may be omitted or briefly described.

[0174] Referring to FIGS. 10 and 11, a plurality of heat-generating parts (100) of a light source assembly (50) according to one embodiment of the present disclosure may be arranged to dissipate heat through a single heat sink (400).

[0175] The heat sink (400) may include a 3D vapor chamber (420) and heat dissipation fins (425).

[0176] For example, a plurality of heating elements (100) of the light source assembly (50) may be provided on the front and side of the light source assembly (50). Accordingly, the 3D vapor chamber (420) of the heat sink (400) may include a plurality of base plates (421) provided to be in contact with each of the plurality of heating elements (100).

[0177] The heat sink (400) may include heat dissipation fins (425) that are coupled vertically to the base plate (421). For example, a plurality of heat-generating parts (100) of the light source assembly (50) may each be provided on the front and side of the light source assembly (50).

[0178] Accordingly, a plurality of base plates (421) in contact with a plurality of heating elements (100) can each be arranged to be in contact with the front and side of the light source assembly (50).

[0179] Accordingly, the heat dissipation fins (425) that are vertically connected to the plurality of base plates (421) can be arranged horizontally.

[0180] The base plate (421) may include a first internal space (422) in which a refrigerant (R) is stored. The heat dissipation fin (425) may include a second internal space (426) in which a refrigerant (R) is stored.

[0181] The second internal space (426) of the heat dissipation fin (425) may be provided to be connected to the first internal space (422) of the base plate (421). Accordingly, the heat dissipation fin (425) including the second internal space (426) may be provided to be in communication with the base plate (421) including the first internal space (422).

[0182] Accordingly, the refrigerant (R) provided in the internal space of the heat sink (400) can be provided to flow in three-dimensional directions.

[0183] In an embodiment of the invention, the heat dissipation fin (425) is illustrated as an example of a heat dissipation fin (425) including a vapor chamber (420) having a second internal space (426), but the concept of the invention is not limited thereto.

[0184] The heat dissipation fin (425) may not include a second internal space (426) inside, or the heat dissipation fin (425) of the heat sink (400) may include both a heat dissipation fin (425) that includes a second internal space (426) inside and a heat dissipation fin (425) that does not include a second internal space (426).
