However, the present invention is not limited to the following embodiments. Further, the following description and drawings are simplified as appropriate for the sake of clarity.

(Embodiment 1)
Hereinafter, the first embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view of a projection device with a housing according to the first embodiment. FIG. 2 is a cross-sectional view showing the configuration of the projection device with the housing according to the first embodiment.

  It should be noted that the right-handed xyz coordinates shown in FIG. 1 and other drawings are, of course, convenient for explaining the positional relationship of the components. Normally, the z-axis plus direction is vertically upward, the x-axis plus direction is front, the x-axis minus direction is backward, the y-axis plus direction is left, the y-axis minus direction is right, and the xy plane is a horizontal plane, which is common between drawings. is there.

  As shown in FIGS. 1 and 2, the projection device 100 with a housing includes a housing 1, a projection device 2, a first partition 3, and a heat exchange fan 4.

  The housing 1 preferably has a structure that allows the projection device 2 to be housed in a removable manner and hermetically sealed. The hermeticity of the housing 1 may be appropriately set so that the projection device 2 can be protected according to the environment in which the housing 1 is placed and the projection device 2. The housing 1 is preferably dustproof. The housing 1 may have, for example, a substantially rectangular parallelepiped shape, and has a bottom surface 1a, a left side surface 1b, a front surface 1c, a right side surface 1d, a back surface 1e, and an upper surface 1f. An opening window 1g is provided on the front surface 1c. The opening window 1g is made of a material through which the projection light L1 of the projection device 2 can pass.

  As shown in FIG. 2, the projection device 2 is arranged inside the housing 1. Specifically, the projection device 2 may be arranged at a predetermined distance from the inner wall surface of the housing 1.

  The projection device 2 may be, for example, a substantially rectangular parallelepiped, and includes a top surface 2d and a back surface 2f. The projection device 2 includes a projection unit 2a, an exhaust port 2b, and an intake port 2c. The projection part 2 a is arranged so as to face the opening window 1 g of the housing 1. The exhaust port 2b is arranged so as to face the inner wall surface corresponding to the left side surface 1b of the housing 1. The intake port 2c is arranged so as to face the inner wall surface corresponding to the right side surface 1d of the housing 1. The upper surface 2d is arranged so as to face the ceiling surface corresponding to the upper surface 1f of the housing 1. When the projection device 2 is operated, it emits projection light L1 from the projection unit 2a.

  Further, the projection apparatus 2 appropriately sucks the gas contained inside the housing 1 into the projection apparatus 2 through the suction port 2c. The projection device 2 causes the sucked gas to flow into the projection device 2 to remove heat from the projection device 2 and cool it. Then, the projection device 2 exhausts the sucked gas to the outside of the projection device 2 through the exhaust port 2b.

  The housing 1 includes a flow path R1 through which gas flows from the exhaust port 2b of the projection device 2 to the intake port 2c. The flow path R1 is a space extending from the exhaust port 2b to the intake port 2c via the rear surface 2f side of the projection device 2. The outer side R2 of the flow path R1 is a space that extends inside the housing 1 from the exhaust port 2b to the intake port 2c via the projection unit 2a side of the projection device 2.

  The first partition 3 partitions the flow path R1 and the outer side R2 of the flow path R1 in the housing 1. Specifically, the first partition 3 partitions the gas so that it does not flow to the front side of the projection device 2. The first partition 3 is arranged on the heat exchange fan 4 side in the outer side R2 of the flow path R1. The first partition 3 mechanically connects the outer wall surface of the projection device 2 and the inner wall surface of the housing 1. The first partition 3 may mechanically connect the bottom surface 1a and the top surface 1f of the housing 1.

  The heat exchange fan 4 is arranged on the inner wall surface of the housing 1 on the flow path R1 side. Further, the heat exchange fan 4 is arranged on the exhaust port 2b side in the flow path R1. The heat exchange fan 4 radiates the heat inside the housing 1 to the outside. When the heat exchange fan 4 operates, heat flows in the direction HP1 and moves to the outside of the housing 1.

  Here, the projection device 2 is operated. Then, the projection apparatus 2 emits the projection light L1 from the projection unit 2a, the projection light L1 passes through the opening window 1g, goes out of the projection apparatus 100 with a housing, and reaches the projection target. The projection target shows an image by the projection light L1.

  The projection device 2 generates heat. Further, the projection device 2 takes in the gas contained inside the housing 1 from the intake port 2c and discharges it from the exhaust port 2b. The exhaust gas discharged from the exhaust port 2b flows through the flow path R1 along the direction FP1. Since the first partition 3 partitions the flow path R1 and the outer side R2 of the flow path R1 in the housing 1, this exhaust gas hardly flows into the outer side R2 from the exhaust port 2b. Therefore, the temperature at the outer side R2 does not rise excessively, and the projection light L1 is hardly affected by the temperature rise. Further, the heat exchange fan 4 is arranged on the exhaust port 2b side in the flow path R1, and the heat of this exhaust can be moved to the outside of the housing 1.

  As described above, according to the configuration of the projection device 100 with a housing, while exhaust gas is caused to flow from the projection device 2 in a predetermined direction by the first partition 3, the heat exchange fan 4 intensively dissipates the heat to the outside of the housing 1. it can. Therefore, even if the housing 1 is sealed, the heat generated by the projection device 2 can be radiated to the outside of the housing 1. That is, it is possible to improve the heat dissipation efficiency.

  Further, when the first partition 3 mechanically connects the floor surface 1aa and the upper surface 1f of the housing 1, heat transfer is promoted to the bottom surface 1a and the upper surface 1f of the housing 1. Thereby, the heat dissipation efficiency can be further improved.

(Embodiment 2)
Hereinafter, the second embodiment will be described with reference to FIG. FIG. 3 is a cross-sectional view showing the configuration of the projection device with a housing according to the second embodiment. The projection device with a housing 200 according to the second embodiment has the same configuration as the projection device with a housing 100 shown in FIGS. 1 and 2 except for a partition and a heat exchange fan. A configuration different from that of the projection device 100 with a housing will be described.

  The projection device 200 with a housing includes a third partition 31, a second partition 32, a fourth partition 33, and heat exchange fans 41, 42, 43. The projection device 200 with a housing may include at least one of the third partition 31, the second partition 32, the fourth partition 33, and the heat exchange fans 41, 42, 43.

  The third partition 31 is provided in the flow path R1 and blocks a part of the flow path R1. The first partition 3 and the third partition 31 sandwich the exhaust port 2b of the projection device 2 and the heat exchange fan 4. The third partition 31 partitions a part of the flow path R1. Specifically, the third partition 31 projects from the rear surface 1e of the housing 1 toward the rear surface 2f of the projection device 2. The third partition 31 is arranged between the first partition 3 and the second partition 32, and partitions a part of the flow path R1 so as to provide the flow path R1 with the projection device 2.

  The second partition 32 is provided in the flow path R1 and blocks a part of the flow path R1. The second partition 32 is arranged between the third partition 31 and the intake port 2c. The second partition 32 partitions a part of the flow path R1 so that the flow path R1 is not provided between the second partition 32 and the projection device 2 and the flow path R1 is provided between the second partition 32 and the inner wall of the housing 1.

  The tip of the third partition 31 is separated from the back surface 2f of the projection device 2, and the second partition 32 is separated from the outer wall surface of the projection device 2. The third partition 31 is separated from one of the outer wall surface of the projection device 2 and the inner wall surface of the housing 1, and the second partition 32 is separated from the other outer wall surface of the projection device 2 and the inner wall surface of the housing 1. I hope you are doing it.

  The projection device 200 with a housing may further include a third partition 31 and a partition having the same configuration as the second partition 32, and the partition is similar to the third partition 31 and the second partition 32. It is good that they are arranged. When the partition is arranged in this manner, the flow path R1 is formed with an S-shaped bent portion.

  The fourth partition 33 is a plate-like body that extends from the first partition 3 along the outer wall surface of the projection device 2 to the second partition 32 through the exhaust port 2b side. The fourth partition 33 may be continuous with the first partition 3 and the second partition 32. The fourth partition 33 may include a passage hole that allows the exhaust gas from the exhaust port 2b to pass therethrough.

  The heat exchange fan 41 is provided on the back surface 1e of the housing 1. The heat exchange fan 42 is provided on the floor surface 1aa of the housing 1. The heat exchange fans 41 and 42 are provided between the exhaust port 2b and the third partition 31. The heat exchange fan 41 radiates the heat inside the housing 1 to the outside. When the heat exchange fan 41 operates, heat flows in the direction HP2 and moves from the inside to the outside of the housing 1. When the heat exchange fan 42 operates, heat flows downward (here, the Z-axis negative side) and moves from the inside to the outside of the housing 1.

  The heat exchange fan 43 is provided on the left side surface 1b of the housing 1. The heat exchange fan 43 is provided so as to face the intake port 2c. The heat exchange fan 43 radiates the heat inside the housing 1 to the outside. When the heat exchange fan 43 operates, the heat of the gas near the intake port 2c flows in the direction HP3 and moves from the inside to the outside of the housing 1. The heat exchange fans 41, 42, 43 may be provided on the upper surface 1f of the housing 1.

  Here, the projection device 2 is operated. Then, the projection device 2 emits projection light L1 from the projection unit 2a, the projection light L1 passes through the opening window 1g, exits outside the projection device 200 with a housing, and reaches the projection target. The projection target shows an image by the projection light L1.

  The projection device 2 generates heat. Further, the projection device 2 takes in the gas contained inside the housing 1 from the intake port 2c and discharges it from the exhaust port 2b. The exhaust gas discharged from the exhaust port 2b flows through the flow path R1 along the direction FP2. Since the first partition 3 partitions the flow path R1 and the outer side R2 of the flow path R1 in the housing 1, this exhaust gas hardly flows into the outer side R2 from the exhaust port 2b. Therefore, the temperature at the outer side R2 does not rise excessively, and the projection light L1 is hardly affected by the temperature rise.

  Further, the third partition 31 and the second partition 32 partition a part of the flow path R1. Therefore, since the exhaust gas passes through the third partition 31 and the second partition 32, the exhaust gas bypasses and flows. Exhaust gas in the housing-equipped projection device 200 is more likely to stay between the first partition 3 and the third partition 31 in the flow path R1 than in the housing-equipped projection device 100 shown in FIGS. 1 and 2. ..

  Further, the heat exchange fans 4, 41, 42 are arranged on the exhaust port 2b side in the flow path R1. The projection device 200 with a housing includes more heat exchange fans than the projection device 100 with a housing. Further, the heat exchange fans 4, 41, 42 are provided on the right side surface 1d, the back surface 1e, and the bottom surface 1a of the housing 1 between the first partition 3 and the third partition 31 in the flow path R1. ..

  As described above, according to the configuration of the projection device 200 with a housing, the exhaust gas is exhausted by the first partition 3, the third partition 31, and the second partition 32 into the first partition 3 and the third partition 31 in the flow path R1. Let it stay in between. Further, the heat exchange fans 4, 41, 42 can centrally dissipate heat to the outside of the housing 1 from the exhaust gas accumulated between the first partition 3 and the third partition 31 in the flow path R1. Therefore, even if the housing 1 is sealed, the heat generated by the projection device 2 can be radiated to the outside of the housing 1. Further, the projection device 200 with a housing can radiate heat to the outside of the housing 1 with higher efficiency than the projection device 100 with a housing.

(Embodiment 3)
The third embodiment will be described below with reference to FIGS. 4 and 5. FIG. 4 is a partially cut lateral cross-sectional view showing the configuration of the projection device with a housing according to the third embodiment. FIG. 5 is a vertical cross-sectional view showing the configuration of the projection device with a housing according to the third embodiment. The projection device with a housing 300 according to the third embodiment has the same configuration as the projection device with a housing 200 shown in FIG. 3 except for the heat conduction member. A configuration different from that of the projection device 200 with a housing will be described.

  As shown in FIGS. 4 and 5, the projection device 200 with a housing includes an upper heat conducting member 51, a lower heat conducting member 52, and heat conducting members 61, 62, 63. Incidentally. The projection device 200 with a housing may include at least one of the upper heat conducting member 51, the lower heat conducting member 52, and the heat conducting members 61, 62, 63. The upper heat conducting member 51, the lower heat conducting member 52, and the heat conducting members 61, 62, 63 may have various shapes. The upper heat-conducting member 51, the lower heat-conducting member 52, and the heat-conducting members 61, 62, and 63 have, for example, an L-shaped cross section, a fin shape, a heat sink shape, a block shape, or the like.

  The upper heat conduction member 51 is provided on the upper surface 2d of the projection device 2. The upper surface 2d often has a curved surface. By providing the upper surface 2d with a curved surface, the flexibility of the design of the projection device 2 may be increased. When the upper surface 2d has a curved surface, the upper heat conducting member 51 may be a spring-shaped body so as to follow the curved surface. The upper heat conducting member 51 mechanically connects the upper surface 2d of the projection device 2 and the ceiling surface 1fa of the housing 1. The upper heat conduction member 51 moves the heat generated by the projection device 2 in the direction HP41 and passes the upper surface 1f of the housing 1. The upper heat conducting member 51 promotes cooling of the projection device 2.

  As shown in FIG. 5, the lower heat conduction member 52 is provided on the bottom surface 2e of the projection device 2. The bottom surface 2e often has a flat surface. When the bottom surface 2e has a flat surface, the lower heat conducting member 52 may be a block-shaped body. The lower heat conduction member 52 mechanically connects the bottom surface 2e of the projection device 2 and the floor surface 1aa of the housing 1. The lower heat conductive member 52 moves the heat generated by the projection device 2 in the direction HP42 and passes through the bottom surface 1a of the housing 1. The lower heat conducting member 52 promotes cooling of the projection device 2.

  When the upper surface 2d has a curved surface and the bottom surface 2e has a flat surface, the contact area between the upper surface 2d and the upper heat conducting member 51 tends to be lower than the contact area between the bottom surface 2e and the lower heat conducting member 52. .. Therefore, in such a case, the heat radiation amount from the bottom surface 2e is larger than the heat radiation amount from the upper surface 2d.

  The heat conducting member 61 is provided on the right side surface 1d of the housing 1. Specifically, the heat conducting member 61 is provided on the right side surface 1d between the exhaust port 2b and the third partition 31. The heat conducting member 61 further dissipates heat from the right side surface 1d of the housing 1 to promote cooling of the projection device 2.

  The heat conducting member 62 is a plate-shaped member extending along the back surface 2f of the projection device 2. Specifically, the heat conduction member 62 is arranged between the fourth partition 33 and the third partition 31. The heat conduction member 62 further radiates heat from the back surface 2f of the projection device 2 to promote cooling of the projection device 2.

  The heat conducting member 63 is provided on the upper surface 1f of the housing 1. Specifically, the heat conduction member 63 is provided between the third partition 31 and the second partition 32 on the upper surface 1f. The heat conduction member 63 further dissipates heat from the upper surface 1f of the housing 1 to promote cooling of the projection device 2.

  Here, the projection device 2 is operated. Then, the projection apparatus 2 emits projection light L1 from the projection unit 2a, the projection light L1 passes through the opening window 1g, exits from the projection apparatus 300 with a housing, and reaches the projection target. The projection target shows an image by the projection light L1.

  The projection device 2 generates heat. Further, the projection device 2 takes in the gas contained inside the housing 1 from the intake port 2c and discharges it from the exhaust port 2b. The exhaust gas discharged from the exhaust port 2b flows along the flow path R1 along the direction FP2, as in the projection device 200 with a housing. Therefore, the exhaust gas in the projection device 300 with a housing stays between the first partition 3 and the third partition 31 in the flow path R1 as compared with the exhaust gas in the projection device 100 with a housing shown in FIGS. 1 and 2. It's easy to do.

  Further, the heat exchange fans 4, 41, 42 are arranged on the exhaust port 2b side in the flow path R1, as in the case of the projection device 200 with a housing. The projection device 300 with a housing includes more heat exchange fans than the projection device 100 with a housing. Further, the heat exchange fans 4, 41, 42 are provided on the right side surface 1d, the back surface 1e, and the bottom surface 1a of the housing 1 between the first partition 3 and the third partition 31 in the flow path R1. ..

  Further, unlike the projection device 200 with a housing, the projection device 300 with a housing includes an upper heat conduction member 51, a lower heat conduction member 52, and heat conduction members 61, 62, 63.

  The upper heat-conducting member 51 and the lower heat-conducting member 52 promote heat dissipation in the up-down direction of the projection device 2. The heat conducting member 61 further dissipates heat from the right side surface 1d of the housing 1. The heat conduction member 62 further radiates heat from the back surface 2f of the projection device 2. The heat conducting member 63 further dissipates heat from the upper surface 1f of the housing 1. These promote the cooling of the projection device 2.

  As described above, according to the configuration of the projection device 300 with a housing, the upper heat conduction member 51, the lower heat conduction member 52, and the heat conduction members 61, 62, and 63 promote heat dissipation of the projection device 2, respectively. Therefore, the housing-equipped projection device 300 can dissipate the heat generated by the projection device 2 to the outside of the housing 1 with higher efficiency than the housing-equipped projection device 200.

(Embodiment 4)
Hereinafter, the fourth embodiment will be described with reference to FIGS. 6 to 8. FIG. 6 is a perspective view of a projection device with a housing according to the fourth embodiment. FIG. 7 is a partially cutaway sectional view showing the configuration of the projection device with a housing according to the fourth embodiment. FIG. 8 is a vertical cross-sectional view showing the configuration of the projection device with a housing according to the fourth embodiment.

  As shown in FIG. 6, the projection device 400 with a housing may be arranged and used in the vicinity of the blower C10. The projection device 400 with a housing may be arranged and used in a position where the wind C1 hits the upper surface 1f of the housing 1 when the blower C10 sends the wind C1. In addition, the projection device 400 with a housing may be arranged and used in an environment where the naturally generated wind C1 hits the upper surface 1f of the housing 1 without the blower C10. The gas forming the wind C1 may be various gases, for example, air.

  As shown in FIGS. 7 and 8, a projection device 400 with a housing has a configuration in which the projection device 300 with a housing shown in FIGS. That is, the projection device 2, the first partition 3, the third partition 31, the second partition 32, the fourth partition 33, the heat exchange fans 4, 41, 42, 43, the upper heat conduction member 51, the lower heat. The conduction member 52 and the heat conduction members 61, 62, 63 are horizontally inverted and vertically inverted in the housing 1 of the projection device 300. Therefore, it should be noted that the top surface 2d, the bottom surface 2e, the upper heat conducting member 51, the lower heat conducting member 52, and the like of the projection device 2 are different in the position indicated by the name and the position where the configuration is arranged. The projection apparatus 2 and the heat exchange fans 4, 41, 42, 43 may be appropriately changed in settings so as to perform a desired operation even if they are horizontally inverted and vertically inverted. In the housing-equipped projection device 400, the projection device 2 may be disposed inside the housing 1 while being turned upside down.

  The upper surface 2d of the projection device 2 faces the floor surface 1aa of the housing 1. The bottom surface 2e of the projection device 2 faces the ceiling surface 1fa of the housing 1. The top surface 2d is located below the bottom surface 2e.

  The upper heat conductive member 51 mechanically connects the upper surface 2d of the projection device 2 and the floor surface 1aa of the housing 1. The upper heat conduction member 51 moves the heat generated by the projection device 2 in the direction HP51 and passes the bottom surface 1a of the housing 1. The upper heat conduction member 51 promotes heat dissipation of the projection device 2.

  The lower heat conduction member 52 mechanically connects the bottom surface 2e of the projection device 2 and the ceiling surface 1fa of the housing 1. The lower heat conductive member 52 moves the heat generated by the projection device 2 in the direction HP52 and passes the upper surface 1f of the housing 1. The lower heat conductive member 52 promotes heat dissipation of the projection device 2. The heat generated by the projection device 2 passes through the upper surface 1f of the housing 1 and is then transferred to the gas near the upper surface 1f. Since the wind C1 is sent to the vicinity of the upper surface 1f, the gas near the upper surface 1f is constantly exchanged. Therefore, the upper surface 1f of the housing 1 is forcibly cooled. The heat generated by the projection device 2 can be passed through the lower heat conducting member 52 and the upper surface 1f of the housing 1 to be radiated with high efficiency.

  When the top surface 2d has a curved surface and the bottom surface 2e has a flat surface, the amount of heat radiation from the bottom surface 2e is larger than the amount of heat radiation from the top surface 2d. The upper surface 1f of the housing 1 is forcibly cooled.

  Here, the projection device 2 is operated. Then, the projection apparatus 2 emits the projection light L1 from the projection unit 2a, the projection light L1 passes through the opening window 1g, goes out of the projection apparatus 400 with a housing, and reaches the projection target. The projection target shows an image by the projection light L1.

  The projection device 2 generates heat. Further, the projection device 2 takes in the gas contained inside the housing 1 from the intake port 2c and discharges it from the exhaust port 2b. The exhaust gas discharged from the exhaust port 2b flows in the flow path R1 along the direction FP2, as in the case of the projection device 300 with a housing. Therefore, the exhaust gas in the projection device 400 with a housing stays between the first partition 3 and the third partition 31 in the flow path R1 as compared with the exhaust gas in the projection device 100 with a housing shown in FIGS. 1 and 2. It's easy to do.

  Further, the heat exchange fans 4, 41, 42 are arranged on the exhaust port 2b side in the flow path R1, as in the case of the projection device 200 with a housing. The projection device 400 with a housing includes more heat exchange fans than the projection device 100 with a housing. Further, the heat exchange fans 4, 41, 42 are provided on the right side surface 1d, the back surface 1e, and the bottom surface 1a of the housing 1 between the first partition 3 and the third partition 31 in the flow path R1. ..

  Further, the projection device 400 with a housing includes an upper heat conduction member 51, a lower heat conduction member 52, and heat conduction members 61, 62, 63, similarly to the projection device 300 with a housing.

  The upper heat-conducting member 51 and the lower heat-conducting member 52 promote heat dissipation in the up-down direction of the projection device 2. The heat conducting member 61 further radiates the heat of the left side surface 1b of the housing 1, the heat conducting member 62 further radiates the heat of the rear surface 2f of the projection device 2, and the heat conducting member 63 the upper surface of the housing 1. The heat of 1f is further radiated. These promote the cooling of the projection device 2.

  Further, in the projection device 400 with a housing, unlike the projection device 300 with a housing, the projection device 2 is horizontally inverted and vertically inverted. The upper surface 1f of the housing 1 is forcibly cooled.

  As described above, according to the configuration of the projection device 400 with a housing, the projection device 2 is horizontally inverted and vertically inverted. The upper surface 1f of the housing 1 is forcibly cooled. Therefore, the projection device 400 with a housing can radiate the heat generated by the projection device 2 to the outside of the housing 1 with high efficiency as compared with the projection device 300 with a housing.

(Example)
Next, an example of the result of analyzing the temperature distribution of the housing-equipped projection device having the same configuration as the housing-equipped projection device 200 shown in FIG.

  In Example 1, the temperature distribution was determined after setting the predetermined conditions, and the results are shown in FIG. The temperature is described in 5 steps of values 1 to 5.

  In Comparative Example 1, the temperature distribution of the housing-equipped projection device having the same configuration as the housing-equipped projection device 900 shown in FIG. 10 was determined, and the results are shown in FIG. 11. The projection apparatus 900 with a housing is different from the projection apparatus 900 provided with the first partition 3, the third partition 31, the second partition 32, the fourth partition 33, and the heat exchange fans 4, 41, 42, 43. The projector 200 with a housing has the same configuration.

  As shown in FIG. 11, in Comparative Example 1, most of the projection device 2 exhibits a temperature value of 5. The region between the outer edge of the projection device 2 and the inner wall surface of the housing 1 showed a temperature value of 2 to 5, and the outer region of the housing 1 had a temperature value of 1.

  As shown in FIG. 9, in Example 1, most of the projection device 2 exhibits temperature values of 3 to 5. The region between the first partition 3 and the third partition 31 in the flow path R1 shows the temperature value 3. Other than these, the region between the outer edge of the projection device 2 and the inner wall surface of the housing 1 showed a temperature value of 2, and the outer region of the housing 1 had a temperature value of 1.

  In Example 1, the temperature inside the housing 1 is generally lower than that in Comparative Example 1. In the first embodiment, the exhaust gas discharged from the exhaust port 2b of the projection device 2 is retained between the first partition 3 and the third partition 31 in the flow path R1. Heat exchange fans 4, 41, 42 exchange heat from their exhaust to the housing 1. As a result, it is presumed that Example 1 efficiently radiated heat from the projection device 2 and had a lower temperature than Comparative Example 1.

(Production method)
In addition, the projection device 100 with a housing may be manufactured by assembling the housing 1, the projection device 2 and other components. The projection device 100 with a housing will be described.

  First, the projection device 2 is placed in the housing 1 (projection device placement step ST1). The projection device 2 may be arranged in the housing 1 so that the housing 1 includes a flow path R1 through which gas flows from the exhaust port 2b of the projection device 2 to the intake port 2c.

  Subsequently, the heat exchange fan 4 and the like are arranged on the inner wall surface of the housing 1 and on the exhaust port 2b side in the flow path R1 (heat exchange fan arrangement step ST2).

  Finally, the first partition 3 and the like are arranged in the housing 1 (partition arrangement step ST3). When the first partition 3 is arranged in the housing 1, it is arranged on the heat exchange fan 4 side on the outer side R2 of the flow path R1 and connects the outer wall surface of the projection device 2 and the inner wall surface of the housing 1. ..

  As described above, the projection device 100 with a housing can be manufactured. The projection device 200, 300, 400 with a housing may be manufactured using a manufacturing method including the steps described above.

  It should be noted that the present disclosure is not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit of the present disclosure. For example, it is possible to make appropriate changes without departing from the spirit. For example, as with the first partition 3, the third partition 31, the second partition 32, and the fourth partition 33 may mechanically connect the floor surface 1aa and the upper surface 1f of the housing 1. Similar to the first partition 3, it promotes the transfer of heat to the bottom surface 1a and the top surface 1f of the housing 1. Thereby, the heat dissipation efficiency can be further improved. Further, the present disclosure may be implemented by appropriately combining the respective embodiments. Further, the projection device with a housing according to each embodiment may have a partial configuration. For example, the same configuration as that of the projection device with housing 100, 200, 300, 400 excluding the projection device 2 may be implemented.
