Is actively going to the fan unit 15.

  The second heat generating component 27 is constituted by a circuit component called a cell processor, for example. The amount of heat generated by the second heat generating component 27 is, for example, about 50 W. Further, as shown in FIG. 3, the second heat generating component 27 is provided at a position away from the first heat generating component 24.

  The third heat generating component 28 is configured by a circuit component such as an I / O controller, for example. The amount of heat generated by the third heat generating component 28 is, for example, about 15W. As shown in FIG. 3, the third heat generating component 28 is disposed at a position overlapping the first heat generating component 24. Other heat generating components include circuit components such as RAM. Accordingly, the heat generation amount of the entire second printed circuit board 12B is, for example, about 50-100 W, and the heat generation amount is larger than that of the first printed circuit board 12A.

  As shown in FIGS. 2 and 3, the third printed circuit board 12C is provided at a position lower than the first printed circuit board 12A. The third printed circuit board 12C is a so-called image processing board. The third printed circuit board 12C is opposed to the first printed circuit board 12A with a gap between the third printed circuit board 12A and the first printed circuit board 12A. The third printed circuit board 12C includes a third printed wiring board 31 and a fourth heat generating component 32 fixed to one surface (upper surface) of the third printed circuit board 12C. The fourth heat generating component 32 is constituted by, for example, a circuit component for image processing. The amount of heat generated by the entire third printed circuit board 12C is, for example, about 1-10 W, which is smaller than that of the first printed circuit board 12A.

  As shown in FIGS. 2, 3, and 5, the first heat pipe 13 </ b> A is used for cooling the second heat generating component 27. The first heat pipe 13A is composed of two pieces, each formed in a rod shape having an outer diameter of 8 mm. The first heat pipe 13A is formed by enclosing a working fluid such as water in a hollow rod-shaped main body formed of, for example, copper. The two first heat pipes 13 </ b> A include a first end portion 33 thermally connected to the second heat generating component 27 and a second end provided on the opposite side of the first end portion 33. Part 34. The first end portion 33 is thermally connected to the second heat generating component 27 via the first heat receiving plate 35. The second end portion 34 is disposed in the vicinity of the fan unit 15.

  More specifically, the second end 34 of the first heat pipe 13Aa faces the lower half 46A of the exhaust port 46 described later of the fan unit 15. The second end portion 34 of the other first heat pipe 13Ab is opposed to an upper half portion 46B of an exhaust port portion 46, which will be described later, of the fan unit 15.

  Note that the two first heat pipes 13A are installed in a so-called top heat state in which the installation height of the heat receiving portion is higher than the installation height of the heat dissipation portion. However, since the two first heat pipes 13A use heat pipes compatible with top heat, a situation in which the cooling performance is not exhibited does not occur. Specifically, a porous layer formed by sintering copper powder with a constant thickness was used for the wick provided on the inner peripheral surface of the first heat pipe 13A.

  The second heat pipe 13 </ b> B is used for cooling the third heat generating component 28. The first heat pipe 13B is formed by enclosing a working fluid such as water inside a hollow rod-shaped main body made of, for example, copper. The second heat pipe 13B includes a third end 37 that is thermally connected to the third heat-generating component 28, a fourth end 38 that is provided on the opposite side of the third end 37, have. The third end portion 37 is thermally connected to the second heat generating component 27 via the second heat receiving plate 39. The fourth end portion 38 is disposed in the vicinity of the exhaust port portion 46 of the fan unit 15. More specifically, the fourth end portion 38 is disposed above the exhaust port portion 46 of the fan unit 15. In addition, as for the 2nd heat pipe 13B, the installation height of a heat receiving part is installed substantially the same as the installation height of a thermal radiation part, and it is not in the top heat state. For this reason, the wick used for the second heat pipe 13B is a plurality of narrow grooves formed on the inner peripheral surface of the second heat pipe 13B.

  In the present embodiment, the fourth end portion 38 is disposed above the exhaust port portion 46, but the present invention is not limited to this. The exhaust port portion 46 may be provided large so that the fourth end portion 38 faces the exhaust port portion 46.

  Further, as shown in FIG. 2, the distance between the fan unit 15 and the second heat generating component 27 is shorter than the distance between the fan unit 15 and the third heat generating component 28. For this reason, the length of the first heat pipe 13A is shorter than the length of the second heat pipe 13B.

  As shown in FIGS. 2 and 3, the first heat sink 14A is connected to the second end 34 of the first heat pipe 13A and the fourth end 38 of the second heat pipe 13B. The heat dissipation of the first heat pipe 13A and the second heat pipe 13B is promoted. The first heat sink 14A is disposed at a position facing an exhaust port 46 of the first fan unit 15 described later. The first heat sink 14 </ b> A has a plurality of fins 41 </ b> A connected to the second end portion 34 and the fourth end portion 38.

  The fan unit 15 is disposed at a position below the second printed circuit board 12B. The fan unit 15 can discharge heat generated from the first to third printed circuit boards 12 </ b> A to 12 </ b> C to the outside of the housing 16. As shown in FIGS. 4 and 6, the fan unit 15 includes a fan main body 42, a box-shaped fan case 43 surrounding the fan main body 42, and a motor 47 that drives the rotation of the fan main body 42. ing. The fan case 43 has a first intake port portion 44 provided in the upper portion, a second intake port portion 45 provided in the lower portion, and an exhaust port portion 46 provided in the side portion.

  The first air inlet 44 connects the inside of the housing 16 and the inside of the fan case 43 continuously. In addition, the second air inlet portion 45 continues the outside of the housing 16 and the inside of the fan case 43. The first fan unit 15 can suck air from the inside of the housing 16 via the first air inlet 44. Similarly, the first fan unit 15 can suck air from the outside of the housing 16 through the second air inlet 45. The first fan unit 15 can send the air blown from the fan main body 42 toward the outside of the first heat sink 14 </ b> A and the housing 16 through the exhaust port 46.

  As shown in FIGS. 6 and 7, the second heat sink 14 </ b> B is thermally connected to the fourth heat generating component 32. The second heat sink 14B has a plurality of heat radiating fins 51 erected upward. The heat radiating fins 51 are arranged in a direction along the direction in which the intake unit 16 </ b> A provided in the housing 16 is connected to the fan unit 15. For this reason, the fourth heat generating component 32 is smoothly cooled without disturbing the air flow from the opening 16A toward the fan unit 15.

  Here, the cooling action of the first and second hard disk drive devices 17A and 17B and the cooling action of the first to fourth heat generating components 32 will be described. As shown in FIG. 2, the first hard disk device 17 </ b> A and the second hard disk device 17 </ b> B are cooled by the air sucked from the outside of the housing 16 by the first auxiliary fan unit 52. The air used for cooling the first hard disk device 17A and the second hard disk device 17B is also used for cooling the power supply circuit component 19. The air used for cooling the power supply circuit component 19 is discharged to the outside of the housing 16 by the action of the second auxiliary fan unit 53.

  As shown in FIG. 6, the heat generated in the first heat generating component 24 is transmitted to the air flowing around and sent to the fan unit 15. The air sent to the fan unit 15 is exhausted to the outside of the housing 15 through the exhaust port 46.

  As shown in FIG. 3, the heat generated in the second heat generating component 27 is transmitted through the first heat receiving plate 35 and the two first heat pipes 13 </ b> A to the second end 34 and the first heat sink. Carried to 14A. At this time, the second end portion 34 of the first heat pipe 13 </ b> A faces the lower half 46 </ b> A of the exhaust port portion 46 of the fan unit 15. Air sucked from the outside of the housing 16 is mainly sent to the lower half 46 </ b> A of the exhaust port 46 via the second intake port 45. For this reason, air having a low temperature is sent to the second end 34 of the first heat pipe 13Aa, so that the second heat generating component 27 is preferentially cooled over the other heat generating components. . Further, the second end 34 of the other first heat pipe 13Ab faces the upper half 46B of the exhaust port 46 of the fan unit 15. The cooling of the second heat generating component 27 is further promoted because the second heat generating component 27 is also cooled by the other first heat pipe 13A.

  The heat generated in the third heat generating component 28 is carried to the fourth end 38 and the first heat sink 14A via the second heat receiving plate 39 and the second heat pipe 13B. At this time, the heat carried to the fourth end 38 and the first heat sink 14 </ b> A is transmitted to the air sent from the fan unit 15 and discharged to the outside of the housing 16.

  As shown in FIGS. 6 and 7, the heat generated by the fourth heat generating component 32 is transmitted to the second heat sink 14B. The heat transmitted to the second heat sink 14B is transmitted to the air sucked from the opening 16A of the housing 16, is sent to the exhaust port 46 of the fan unit 15, and is then discharged to the outside of the housing 16. . Since the heat generation amount of the fourth heat generating component 32 is small, the fourth heat generating component 32 is sufficiently cooled also by the second heat sink 14B.

  According to the first embodiment, the television connection device 11 includes a first printed circuit board 12A having a first printed wiring board 23 and a first heat generating component 24 fixed to the first printed wiring board 23, and a second printed circuit board 12A. The printed wiring board 26, the second heat generating component 27 and the third heat generating component 28 fixed to the printed wiring board 26, have a heat generation amount larger than that of the first printed circuit board 12A, and the first printed circuit board. A second printed circuit board 12B facing the first printed circuit board 12A with a gap at a position above the circuit board 12A, a third printed wiring board 31, and a fourth fixed to the second printed circuit board 31 The first printed circuit board 12A having a heat generation amount smaller than that of the first printed circuit board 12A and having a gap at a position below the first printed circuit board 12A. A third facing the plate 12A The lint circuit board 12C, the first printed circuit board 12A, the second printed circuit board 12B, and the housing 16 that accommodates the third printed circuit board 12C, the housing 16 and the housing 16 And a fan unit 15 that discharges heat generated from the first printed circuit board 12A, the second printed circuit board 12B, and the third printed circuit board 12C to the outside of the housing 16.

  According to this configuration, the heat generated from the first to fourth heat generating components 24, 27, 28, and 32 by the fan unit 15 can be released to the outside of the housing 16. At this time, since the second printed circuit board 12B having the largest amount of heat generation is arranged at the top, the heat generated from the second printed circuit board 12B adversely affects the other printed circuit boards. Can be prevented.

  In this case, the second heat generating component 27 and the third heat generating component 28 are fixed to the lower surface of the second printed wiring board 26, and the second printed circuit board 12 B overlaps the upper side of the fan unit 15. Has been placed. According to this configuration, the second printed wiring board 26 acts like a lid, and heat generated from the second heat generating component 27 and the third heat generating component 28 is transferred to the lower side of the second printed wiring board 26. The fan unit 15 disposed in the space can be efficiently discharged outside the housing 16.

  The television connection device 11 of the present embodiment is provided with a first end 33 that is thermally connected to the second heat-generating component 27, on the opposite side of the first end 33, and in the vicinity of the fan unit 15. A first heat pipe 13Aa having a second end portion 34, and the fan unit 15 includes a fan main body 42 and a fan case 43 surrounding the fan main body 42. The fan case 43 is provided at the upper part, and the first intake port portion 44 that connects the inside of the casing 16 and the inside of the fan case 43 is continuous. A second intake port portion 45 that is continuous with the inside, and an exhaust port portion 46 that is provided on the side and for sending air from the fan main body 42 toward the outside of the housing 16. 2 heating parts 2 The amount of heat generation is larger than the heating value of the third heat generating component 28, a second end portion 34 is disposed to face the lower halves 46A of the outlet portion 46.

  According to this configuration, the air sucked from the outside of the housing 16 through the second air inlet 45 is mainly sent toward the lower half 46 </ b> A of the air outlet 46. Therefore, the second end portion 34 of the first heat pipe 13Aa connected to the second heat generating component 27 having a large heat generation amount is efficiently cooled, and the second heat generating component 27 is cooled to other heat generating components. Can be preferentially performed.

  The television connection device 11 is provided with a third end portion 37 thermally connected to the third heat generating component 28 and an exhaust port portion of the fan unit 15 provided on the side opposite to the third end portion 37. A second heat pipe 13B having a fourth end 38 disposed in the vicinity of 46. According to this, the 3rd heat-emitting component 28 can be cooled with the 2nd heat pipe 13B. At this time, since the fourth end portion 38 of the second heat pipe 13B is not disposed in the lower half 46A of the exhaust port portion 46 of the fan unit 15, the cooling of the third heat generating component 28 is performed. The efficiency is inferior to the cooling efficiency of the second heat generating component 27. However, since the heat generation amount of the third heat generating component 28 is smaller than the heat generation amount of the second heat generating component 27, the cooling efficiency may be inferior. Rather, by devising the layout of the first heat pipe 13A and the second heat pipe 13B, it is possible to achieve cooling of each heat generating component according to the priority.

  As in the present embodiment, the first heat pipe 13A connected to the second heat generating component 27 of the second printed circuit board 12B at the top is connected to the fan below the first printed circuit board 12A. If it is routed to the vicinity of the unit 15, that is, to the lower half 46 </ b> A of the exhaust port 46, the first printed circuit board 12 </ b> A in the intermediate position may interfere with the first heat pipe 13 </ b> A. is there. In the present embodiment, the first printed circuit board 12A is disposed at a position that overlaps with the second heat pipe 13B and is separated from the first heat pipe 13A. According to this, it is possible to prevent the first heat pipe 13A and the first printed circuit board 12A from interfering with each other.

  Usually, the shorter the length of the heat pipe, the better the heat transport performance of the heat pipe. In the present embodiment, the distance between the fan unit 15 and the second heat generating component 27 is shorter than the distance between the fan unit 15 and the third heat generating component 28. For this reason, the length of the first heat pipe 13A can be made shorter than that of the second heat pipe 13B. Thereby, the heat transport amount of the first heat pipe 13A can be increased, and the second heat generating component 27 can be efficiently cooled.

  Further, the third heat generating component 28 is provided at a position overlapping the first heat generating component 24, and the second heat generating component 27 is provided at a position away from the first heat generating component 24. According to this configuration, the second heat generating component 27 having a large heat generation amount can be arranged at a position away from the first heat generating component 24. As a result, it is possible to prevent heat from being concentrated at one location inside the housing 16.

  The television connection device 11 is provided in the housing 16 and has an opening 16A through which air can be taken into the housing 16 from the outside, and a plurality of heat radiation fins for promoting cooling of the fourth heat generating component 32. The plurality of heat radiation fins 51 are arranged in a direction along the direction connecting the opening 16 </ b> A and the fan unit 15. According to this configuration, the flow of air sent from the opening 16A toward the fan unit 15 is not disturbed by the radiating fins 51, and the cooling of the fourth heat generating component 32 and the first and second heat pipes are performed. The cooling of 13B can be performed smoothly.

In this embodiment, the filter 60 is configured to be attachable to and detachable from the filter support portion 63 along the direction of the arrow denoted by reference numeral 90. Then, the filter 60 is inserted into the filter support portion 63 by the user. Further, the filter 60 is pulled out from the filter support 63 by the user.

  Further, when the filter 60 is attached to the filter support portion 63, it is desirable that the second intake port portion (air intake portion) 45 be reliably covered by the filtering portion 61.

The filter 60 is inserted into or extracted from the filter support 63 along the direction of the arrow 90.
