Description

Technical Field

[0002] Laser projectors have very high heat dissipation requirements, mainly because laser projectors generate a lot of heat during operation. The internal components of laser projectors are very sensitive to temperature, especially the light source, so the heat dissipation requirements are relatively stringent. In order to maintain the long-term reliability and performance of laser projectors, effective heat dissipation measures must be taken. At present, the heat dissipation of the light source of laser projectors adopts the method of laser radiator and fan, that is, the radiator conducts the heat source and then discharges it out of the casing through the fan to ensure that it can still maintain the best performance in a high temperature environment.

[0003] However, the RGB three-color laser light source has high temperature requirements. The current air cooling method of using a radiator plus a fan has low heat dissipation efficiency, especially when the ambient temperature is relatively high. It is difficult to meet the heat dissipation requirements, so the heat dissipation of the light source cannot meet the ideal requirements, and the light output effect and color stability are poor.

[0041] Figure 1 It is an assembly schematic diagram of a preferred embodiment of the three-color laser light source heat dissipation device of the utility model. Figure 2 It is a schematic diagram of an exploded view of a preferred embodiment of the three-color laser light source heat dissipation device of the utility model. Figure 3 It is a schematic diagram of an exploded view of a preferred embodiment of a first laser light source and a first heat dissipation water-cooling component of a three-color laser light source heat dissipation device of the utility model.

Figure 1-4 The three-color laser light source heat dissipation device of the present utility model is further described as follows.

[0042] like Figure 1-2 As shown, the three-color laser light source heat dissipation device of the present invention includes a light source assembly 100, a first heat dissipation water cooling assembly 200 and a second heat dissipation water cooling assembly 300. Figure 1-2 As shown, the first heat dissipation water cooling assembly 200 and the second heat dissipation water cooling assembly 300 are vertically arranged on both sides of the light source assembly 100 .

[0043] The light source assembly 100 includes a first laser light source 110 and a second laser light source 120. Here, the main function of the light source assembly 100 is to fix the three groups of red, green and blue laser light sources, and combine them into a group of white light through the internal light combining structure for use by the projector. Therefore, any known light source assembly in the art can be used, and no further description is given here. Since the light source assembly 100 includes three groups of red, green and blue laser light sources, at least one of the first laser light source 110 and the second laser light source 120 is a composite light source. In a preferred embodiment of the utility model, the first laser light source 110 is a red laser light source, and the second laser light source 120 is a blue-green laser light source. In another preferred embodiment of the utility model, the first laser light source 110 is a blue laser light source, and the second laser light source 120 is a red-green laser light source. In another preferred embodiment of the utility model, the first laser light source 110 is a green laser light source, and the second laser light source 120 is a red-blue laser light source. Since the red laser light source is more sensitive to temperature, the embodiment in which the first laser light source 110 is a red laser light source and the second laser light source 120 is a blue-green laser light source is more preferred.

[0044] like Figure 3 As shown, the first heat dissipation water cooling assembly 200 includes a first water pump 210, a first water cooling row 220, a first water tank 230, a first water pipe 240, a first water cooling head 250 and a first fan 260. The first laser light source 110 is arranged on the first water cooling head 250, the first water tank 230 is installed on the first water cooling row 220, and the first water pipe 240 connects the first water pump 210, the first water cooling row 220 and the first water cooling head 250 to form a first sealed heat dissipation water path. Coolant is injected into the first sealed heat dissipation water path to cool the first laser light source 110; the first fan 260 is arranged between the first water cooling row 220 and the first water cooling head 250.

[0045] like Figure 4 As shown, the second heat dissipation water cooling component 300 includes a second water pump 310, a first water cooling row 320, a second water tank 330, a second water pipe 340, a second water cooling head 350 and a second fan 360; the second laser light source 120 is arranged on the second water cooling head 350, the second water tank 330 is installed on the first water cooling row 320, and the second water pipe 340 connects the second water pump 310, the first water cooling row 320 and the second water cooling head 350 to form a second sealed heat dissipation water path; coolant is injected into the second sealed heat dissipation water path to cool the second laser light source 120; the second fan 360 is arranged between the first water cooling row 320 and the second water cooling head 350.

[0046] In this preferred embodiment, the first fan 260 is arranged between the first water-cooling row 220 and the first water-cooling head 250, and the second fan 360 is arranged between the first water-cooling row 320 and the second water-cooling head 350, which can better save space and thus reduce the volume of the entire device.

[0047] In other preferred embodiments of the utility model, the first fan 260 can be set on one side of the first water-cooling row 220, and the second fan 360 can be set on the first water-cooling row 320, and they are respectively at a certain distance from the first water-cooling head 250 and the second water-cooling head 350, so that it is convenient for the fans to enter the air. As mentioned above, the first fan 260 can be set on the side of the first water-cooling row 220 facing the first water-cooling row 220 (that is, located between the two and spaced from each other or located between the two and close to each other), and the second fan 360 can be set on the side of the first water-cooling row 320 facing the second water-cooling row 320 (that is, located between the two and spaced from each other or located between the two and close to each other). For another example, the first fan 260 can be set on the side of the first water-cooling row 220 facing away from the first water-cooling row 220, and the second fan 360 can be set on the side of the first water-cooling row 320 facing away from the second water-cooling row 320. In the present invention, the first water pipe 240 connects the first water pump 210, the first water-cooling row 220 and the first water-cooling head 250 to form a first sealed heat dissipation water path, and the first laser light source 110 is arranged on the first water-cooling head 250. Therefore, after starting the first water pump 210, the coolant circulates between the first water-cooling row 220 and the first water-cooling head 250 under the action of the first water pump, and the heat generated by the first laser light source 110 is transferred to the coolant through the first water-cooling row 220, thereby realizing the heat dissipation of the first laser light source 110. It dissipates heat by water cooling, and uses a water cooling component to take away heat through liquid circulation. Compared with air cooling, it has higher heat conduction efficiency, can more effectively reduce the temperature inside the device, and can better ensure the stable operation of the laser projector.

[0048] Similarly, the second water pipe 340 connects the second water pump 310, the first water-cooling row 320 and the second water-cooling head 350 to form a second sealed heat dissipation water path, and the second laser light source 120 is arranged on the second water-cooling head 350. After the second water pump 310 is started, the coolant circulates between the second water-cooling row 320 and the second water-cooling head 350 under the action of the second water pump, and the heat generated by the second laser light source 210 is transferred to the coolant through the second water-cooling row 320, thereby realizing the heat dissipation of the second laser light source 210. It dissipates heat by water cooling, and uses a water cooling component to take away heat through liquid circulation. Compared with air cooling, it has higher heat conduction efficiency, can more effectively reduce the temperature inside the device, and can better ensure the stable operation of the laser projector.

[0049] exist Figure 3-4 In the preferred embodiment shown, a first fan 260 and a second fan 360 are further provided; the first fan 260 is provided between the first water-cooling row 220 and the first water-cooling head 250; the second fan 360 is provided between the first water-cooling row 320 and the second water-cooling head 350. Therefore, when the fan and the water pump are started, the coolant circulates between the water-cooling row and the water-cooling head under the action of the water pump. The heat of the laser light source is transferred to the coolant passing through the water-cooling head. Under the action of the water pump, the coolant is transported to the water-cooling row to remove the heat. Under the action of the fan, the heat is transferred to the surrounding mirror air, and the actual heat exchange is performed. The cooled liquid returns to the water outlet of the water-cooling row and finally flows into the water inlet of the water-cooling head to form a heat dissipation cycle. Therefore, in the liquid cooling mode, further providing a fan can better discharge the heat, further reduce the temperature inside the device, more effectively reduce the temperature inside the device, and better ensure the stable operation of the laser projector. Moreover, in the heat dissipation control, the flow rate of the water pump and the fan speed can be controlled respectively to adjust to achieve precise control of the heat source temperature.

[0050] In a further preferred embodiment of the present invention, a water cooling radiator and a water cooling head with a special structure and position arrangement are designed, which can better dissipate heat on the basis of the above-mentioned embodiments. Of course, in other preferred embodiments of the present invention, other structures and position arrangements can also be adopted, which all fall within the protection scope of the present invention.

[0051] Figure 5 It is a schematic diagram of a preferred embodiment of a water-cooled head of a three-color laser light source heat dissipation device of the utility model. Figure 6 Schematic diagram of a preferred embodiment of the internal heat dissipation teeth of the water cooling head of the three-color laser light source heat dissipation device of the utility model. Figure 5-6As shown, the first water cooling head 250 and the second water cooling head 350 may respectively include a hollow base 51, a water inlet 52 and a water outlet 53 arranged on both sides of the hollow base 51; a corresponding laser light source is installed on the first outer surface of the hollow base 51; and fine heat dissipation teeth 54 are arranged on the inner side of the hollow base 52. The size and device of the hollow base 51 match the shape and size of the corresponding laser light source for installation.

[0052] Since the water cooling head is provided with water inlets and outlets respectively and fine heat dissipation fins are arranged inside, the heat of the light source can be better conducted to the liquid flowing through the inside of the water cooling head.

[0053] Figure 7 Schematic diagram of a preferred embodiment of the water cooling row of the three-color laser light source heat dissipation device of the utility model. Figure 7 As shown, the first water-cooling row 220 and the first water-cooling row 320 may respectively include a water inlet 21, a water outlet 22 and a plurality of water channels 23; the corresponding first water tank 230 or the second water tank 330 are respectively installed on both sides of the water-cooling row, and the two water tanks are connected through the plurality of water channels 23 to form a sealed cavity; the coolant enters and exits the sealed cavity through the water inlet 21 and the water outlet 22; and wave-shaped heat dissipation teeth 24 are respectively arranged on both sides of the plurality of water channels 23.

[0054] Since the water cooling radiator is respectively provided with water inlets and outlets, water tanks are arranged on both sides of the radiator, and the two water tanks are connected together by multiple groups of water channels to form a closed cavity, and wavy heat dissipation teeth are respectively arranged on both sides of the multiple groups of water channels, which can also better export the heat of the liquid passing through the water channels.

[0055] In a preferred embodiment of the utility model, a red laser light source is installed on the first water cooling head 250, and the cooling channel formed by the first water cooling row 220 and the first water cooling head 250 is used to cool the red laser light source, so the volume of the first water cooling row 220 and the first water cooling head 250 can be relatively small. When the first water cooling row 220 is set close to the shell of the projector, it can be set close to the shell of the projector with a smaller area. The second water cooling head 350 is installed with a blue-green laser light source; the volume of the second water cooling row 320 and the second water cooling head 350 needs to be larger, so when the second water cooling row 320 is set close to the shell of the projector, it can be set close to the shell of the projector with a larger area, so as to better dissipate heat. That is, the first water cooling row 220 matches the shape of the first shell of the projector to which it is attached, and the first water cooling row 320 matches the shape of the second shell of the projector to which it is attached; the surface area of ​​the first shell is greater than the surface area of ​​the second shell, and the first shell and the second shell are perpendicular to each other, that is, the first water cooling row 220 and the first water cooling row 320 are perpendicular to each other.

[0056] In this preferred embodiment, water inlets and outlets are respectively provided on the water cooling head, and fine heat dissipation fins are provided inside to facilitate the conduction of the heat of the corresponding light source to the liquid flowing through the inside of the water cooling head. Water inlets and outlets are respectively provided on the water cooling row, and water tanks are provided on both sides of the water row. The two water tanks are connected together through multiple groups of water channels to form a closed cavity. Wave-shaped heat dissipation teeth are respectively provided on both sides of the multiple groups of water channels to extract the heat of the liquid passing through the water channels. When the fan and the water pump are started, the coolant circulates between the water cooling row and the water cooling head under the action of the water pump. The heat of the light source is transferred to the coolant passing through the water cooling head through the heat dissipation teeth inside the water cooling head. Under the action of the water pump, the coolant is transported to the water inlet of the water cooling row. The coolant extracts the heat through the wave-shaped heat dissipation fins on the multiple groups of water channels. Under the action of the fan, the heat is transferred to the surrounding mirror air, which is actually a cold and hot exchange. The cooled liquid returns to the water outlet of the water cooling row and finally flows into the water inlet of the water cooling head to form a heat dissipation cycle. The water cooling radiator is set close to the projector housing, so that the heat can be directly discharged out of the housing through the fan. In the heat dissipation control, the flow rate of the water pump and the fan speed can be adjusted respectively to achieve precise control of the heat source temperature.

[0057] Therefore, the three-color laser light source heat dissipation device of the utility model is implemented, and the heat is removed by liquid circulation through the water cooling component, which has a higher heat conduction efficiency than air cooling, and can more effectively reduce the temperature inside the equipment to ensure the stable operation of the laser projector. The water cooling component can achieve more precise temperature control to meet the power drop and color inaccuracy caused by temperature instability of the projector light source; the water cooling component operates stably and is not easily affected by the external environment. It can continuously provide a stable cooling effect to ensure the long-term stable operation of the projector. Because the water cooling component can effectively reduce the operating temperature, it can extend the service life of the laser light source, reduce the replacement frequency, and reduce maintenance costs.

[0060] The red light source heat dissipation water cooling assembly 200 and the blue-green light source heat dissipation water cooling assembly 300 are arranged perpendicular to each other; the first water cooling row 220 is arranged close to the first shell of the projector; the first water cooling row 320 is arranged close to the second shell of the projector, the first shell and the second shell are perpendicular to each other, and the second fan 360 is arranged between the first water cooling row 320 and the second water cooling head 350.

[0061] The first water cooling head 250 and the second water cooling head 350 may respectively include a hollow base 51, a water inlet 52 and a water outlet 53 arranged on both sides of the hollow base 51; a corresponding laser light source is installed on the first outer surface of the hollow base 51; and fine heat dissipation teeth 54 are arranged on the inner side of the hollow base 52. The size and device of the hollow base 51 match the shape and size of the corresponding laser light source for installation. The first water cooling row 220 and the first water cooling row 320 may respectively include a water inlet 21, a water outlet 22 and a plurality of water channels 23; the corresponding first water tank 230 or second water tank 330 is respectively installed on both sides of the water cooling row, and the two water tanks are connected through the plurality of water channels 23 to form a sealed cavity; the coolant enters and exits the sealed cavity through the water inlet 21 and the water outlet 22; and wave-shaped heat dissipation teeth 24 are respectively arranged on both sides of the plurality of water channels 23.

[0062] The first water cooling head 250 is provided with a red laser light source, and the cooling channel formed by the first water cooling row 220 and the first water cooling head 250 is used to cool the red laser light source, so the volume of the first water cooling row 220 and the first water cooling head 250 can be relatively small.

That is, the first water cooling row 220 matches the shape of the first shell of the projector to which it is attached, and the first water cooling row 320 matches the shape of the second shell of the projector to which it is attached; the surface area of ​​the first shell is greater than the surface area of ​​the second shell, and the first shell and the second shell are perpendicular to each other, that is, the first water cooling row 220 and the first water cooling row 320 are perpendicular to each other.

[0063] Therefore, the three-color laser light source heat dissipation device of the utility model is implemented, and the heat is removed by liquid circulation through the water cooling component, which has a higher heat conduction efficiency than air cooling, and can more effectively reduce the temperature inside the equipment to ensure the stable operation of the laser projector. The water cooling component can achieve more precise temperature control to meet the power drop and color inaccuracy caused by temperature instability of the projector light source; the water cooling component operates stably and is not easily affected by the external environment. It can continuously provide a stable cooling effect to ensure the long-term stable operation of the projector. Because the water cooling component can effectively reduce the operating temperature, it can extend the service life of the laser light source, reduce the replacement frequency, and reduce maintenance costs.
