Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. In the present specification, the terms "upper", "inner", "middle", "left", "right" and "one" are used for convenience of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the corresponding parts may be changed or adjusted without substantial technical changes.

As shown in fig. 1-2 and 5-6, the dustproof heat dissipation chassis for a vehicle-mounted computer comprises a housing 1, a heat dissipation fan 2, an air blower 3 and a bottom shell 4, wherein the bottom of the housing 1 is an opening 12, mounting plates 5 are fixed on two sides of the opening 12, a socket 11 is formed at an end of the housing 1, the bottom shell 4 is inserted into the socket 11 and is used for covering the opening 12, a circuitous air inlet 6 is formed between a side edge of the bottom shell 4 and the mounting plates 5, the air inlet 6 is covered with a piece of breathable dustproof cloth, and the heat dissipation fan 2 is fixed in the housing 1 above the air inlet 6; the bottom of the bottom shell 4 is provided with an air outlet 41, and a filter screen is covered on the air outlet 41; the blower 3 is detachably fixed at the bottom of the bottom case 4, the air outlet direction of the blower 3 is parallel to the bottom surface of the bottom case 4, and the air outlet 41 of the blower 3 faces the side of the air outlet 41 through a check valve 7.

In the shell 1, the heat can be dissipated and exhausted towards the air outlet 41 through the heat dissipating fan 2, and the air can be blown to dissipate heat on the bottom shell 4 through the air blower 3, and the key is that a circuitous air inlet 6 is formed between the mounting plate 5 and the bottom shell 4, and the air-permeable dustproof cloth is laid on the air inlet 6, so that dust outside the case is difficult to enter the shell 1 of the case, and the first-step dustproof effect is achieved; meanwhile, after the vehicle-mounted computer is stopped, namely after the cooling fan 2 stops working, the filter screen on the air outlet 41 can prevent dust from flowing backwards, and in combination with the blowing and cooling effects of the blower 3, the dust is difficult to enter the shell 1 through the air outlet 41, so that the second step of dust prevention effect can be achieved; in combination with the staged work of the cooling fan 2 and the blower 3, when the vehicle-mounted computer works, the air discharged by the cooling fan 2 brings the heat in the shell 1 out to the air outlet 41; when the vehicle-mounted computer stops working, the air blower 3 blows air, the check valve 7 is opened, heat dissipation airflow is formed on the bottom shell 4, and heat of the shell 1 is taken away, so that the machine box has good heat dissipation and dust prevention functions simultaneously through two-step dust prevention effects and the heat dissipation fan 2 and the air blower 3 which work in stages.

In use, since bottom case 4 is located at the bottom of housing 1, dust is easily accumulated, and therefore, bottom case 4 can be pulled out from socket 11 to clean dust on bottom case 4. Certainly, on some occasions where the heat dissipation requirement is greater than the dustproof requirement, the bottom shell 4 can be configured to cover the area of the opening 12, so that more heat dissipation areas are exposed, air can be supplied and exhausted in a larger amount, and the heat dissipation efficiency is improved. For the situation that the heat dissipation requirement and the dustproof requirement are compatible, the structure of the sealed shell 1 of the embodiment is adopted, and only the air inlet 6, the air outlet 41 and the socket 11 are arranged at the bottom of the shell, so that good heat dissipation and dustproof effects can be achieved as described above. For the occasion that the heat dissipation requirement is less than the dustproof requirement, the heat dissipation fan 2 can be turned off, heat dissipation is performed at the bottom of the bottom case 4 only through the blower 3, and particularly, the air outlet 41 can be turned off through the check valve 7, so that excessive dust is prevented from entering the housing 1 from the air outlet 41.

The air-permeable dustproof cloth and the filter screen can be fastened by screws or fixed by bonding. It can be understood that the air-permeable dustproof cloth of the present embodiment has an air-permeable resistance greater than that of the filter screen, so that the air-permeable dustproof cloth with a larger area is configured to filter air, and then the air enters the housing 1 through the air inlet 6, so as to balance the pressure of the air outlet 41. The detachable mode of the air blower 3 can adopt the modes of clamping, buckling and inserting to realize detachable connection. The blower 3 can be arranged in a mounting shell and is detachably connected with the bottom shell 4.

As shown in fig. 4 and 5, in order to keep the hot air out of the casing 1, the air outlet 41 is fixed with the air outlet barrel 8 in a detachable manner below the air outlet barrel 8, the detachable manner of the air outlet barrel 8 can be realized by clamping, buckling and plugging, and the air outlet barrel 8 can be detached when the bottom case 4 is taken out from the socket 11. The air outlet barrel 8 is communicated with the air outlet 41 in a sealing mode, a side air opening 81 is formed in the barrel wall of the air outlet barrel 8, the air outlet 41 of the air blower 3 is opposite to the side air opening 81, and the check valve 7 is hinged to the side wall of the air outlet barrel 8 and is switched between the positions of the side air opening 81 and the air outlet 41. Therefore, when the vehicle-mounted computer works, the heat radiation fan 2 works to discharge hot air from the shell 1 to the air outlet 41 and far away from the shell 1 through the air outlet cylinder 8, and at the moment, the check valve 7 closes the side air opening 81, so that the hot wind energy in the shell 1 is discharged outwards in a concentrated manner. When the vehicle-mounted computer stops working, the heat radiation fan 2 stops working, the air blower 3 is started, the check valve 7 is pushed to close the air outlet 41, air outlet of the air blower 3 is avoided, and dust is brought into the shell 1 through the air outlet 41. Wherein, can dispose check valve 7's structure, make its rotation back whole seal air outlet 41, perhaps partially seal air outlet 41, can understand, when check valve 7 partially seals air outlet 41, check valve 7 possesses comparatively simple and easy structure, for example adopts an arc, articulates at play dryer 8 inner wall through the hinge.

As shown in fig. 2 and 4, in order to reduce the air outlet resistance, discharge the hot air to a farther distance and avoid the dust backflow, the air outlet 41 of the present embodiment is circular, and correspondingly, the air outlet barrel 8 is hollow and cylindrical, and the connection portion between the air outlet barrel 8 and the air outlet 41 is in circular arc transition, so that the dust accumulated on the bottom case 4 can be more easily discharged from the air outlet 41. Specifically, an arc transition portion may be provided at the upper end opening of the outlet duct 8.

As shown in fig. 5, in order to better collect dust, the bottom case 4 has a bottom plate 42 and a surrounding wall 43, the surrounding wall 43 is located at the periphery of the bottom plate 42, and the surrounding wall 43 protrudes from the bottom plate 42, so that dust can be collected on the surface of the bottom plate 42, and the dust is prevented from freely climbing to the inner wall of the housing 1, and more importantly, the surface of the bottom plate 42 of the embodiment is an inclined surface 44 inclined towards the air outlet 41, so that dust accumulated on the surface of the bottom plate 42 can be more easily carried out to the air outlet 41. Therefore, on one hand, the dust is accumulated when the heat radiation fan 2 stops working, on the other hand, when the heat radiation fan 2 starts working, the dust can be discharged in a trading way, and the problem of difficult dust accumulation when the dust is difficult to discharge is solved.

As shown in fig. 5, preferably, the number of the inclined surfaces 44 of the present embodiment is at least two, and each inclined from both sides of the bottom plate 42 toward the middle of the bottom plate 42. It can be understood that the more the number of the inclined surfaces 44 is, the more easily the dust on the surface of the bottom plate 42 is carried out to the air outlet 41, when the number of the inclined surfaces 44 is nearly infinite, the surface of the bottom plate 42 becomes a conical surface to discharge the heat and dust in a manner of approaching smooth and funnel-like, and since the area of the air outlet 41 is smaller than the inner space of the housing 1, the hot air will rapidly increase the speed at the air outlet 41 to discharge the hot air farther. In order to accurately align the heat dissipation fan 2 with the CPU of the vehicle-mounted computer and to make the heat dissipation fan 2 take away more heat exhausted by the CPU, the CPU is usually eccentrically disposed inside the housing 1, and therefore the air outlet 41 of the present embodiment is eccentrically disposed on the bottom plate 42 to better correspond to the CPU.

In the case where the dustproof requirement is greater than the heat dissipation requirement, in one embodiment, a smooth sticker is detachably attached to the surface of the bottom plate 42, so that the smooth sticker to which a new one is attached can be directly replaced after the bottom case 4 is pulled out, to replace the old one on which dust is accumulated. In another embodiment, the bottom plate 42 has a plurality of heat dissipation holes arranged at intervals, and the heat dissipation holes are configured to be small enough to discharge hot air under the driving of the air flow of the heat dissipation fan 2 or the blower 3, but dust is hard to enter.

As shown in fig. 3, in order to better fix the bottom shell 4, the inner wall of the housing 1 of this embodiment is provided with a flange 13 for supporting the bottom shell 4, and the flange 13 is padded with a rubber pad 14, so that after the bottom shell 4 is inserted into the socket 11, one end of the bottom shell is supported by the flange 13, and the other end is supported on the socket 11. Furthermore, a handle 45 extends from the side of the bottom shell 4 to facilitate the maintenance personnel to assemble and disassemble the bottom shell 4; the end of the mounting plate 5 is provided with at least two mounting holes 51, so as to better fasten the bottom shell 4 on the bracket of the vehicle body; in addition, in situations where dust protection requirements are more stringent, a curtain may be installed over the receptacle 11 to reduce the ingress of dust into the receptacle 11.

The embodiment of the present invention is not limited to this, according to the above-mentioned content of the present invention, the common technical knowledge and the conventional means in the field are utilized, without departing from the basic technical idea of the present invention, the present invention can also make other modifications, replacements or combinations in various forms, all falling within the protection scope of the present invention.
