[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Example 1

[0023] See also Figure 1 As shown, this embodiment provides an outdoor spread spectrum tracking receiver chassis 4 structure, wherein the spread spectrum tracking receiver includes a main board 1, a 24V adapter board 2 and a receiver board 3; the main board 1, the 24V adapter board 2 and the receiver board 3 are all arranged in the chassis 4.

[0024] In this embodiment, the air duct design of the chassis 4 is performed as follows:

[0025] The upper half of the chassis 4 is provided with a windshield 5 extending in the vertical direction, and the chassis 4 is divided into a first side and a second side by the windshield 5; wherein, the main board 1 and the 24V adapter board 2 are arranged in the lower half of the first side of the chassis 4, and the receiver board 3 is arranged in the upper half of the second side of the chassis 4; by respectively arranging the main board 1 and the receiver board 3 at two far-apart corners of the chassis 4, it is possible to avoid the internal heat of the chassis 4 from being concentrated in the same piece, and on the other hand, it is possible to reserve wiring space for the wiring of the interface between the two.

[0026] See also Figure 3 and Figure 5 As shown, in this embodiment, a heat dissipation fan 6 is provided at the top of the receiver board 3 and between the main board 1 and the 24V adapter board 2, and a first heat dissipation hole array 7 is provided at the bottom of the first side of the chassis 4, a second heat dissipation hole array 8 is provided at the top of the second side of the chassis 4, and a third heat dissipation hole array 9 is provided on the side wall of the second side of the chassis 4, so that an inverted "Y"-shaped air duct is formed through the first heat dissipation hole array 7, the second heat dissipation hole array 8 and the third heat dissipation hole array 9.

[0027] See also Figure 2 As shown, through the above-mentioned air duct design, the airflow of the heat dissipation fan 6 on the top of the receiver board 3 is divided into two. One path enters the first side of the chassis 4 under the suction of the heat dissipation fan 6 on the first side of the chassis 4, and is cooled by the 24V adapter board 2, and then the mainboard 1 is cooled by the heat dissipation fan 6, and finally discharged from the first heat dissipation hole array 7; the other path goes vertically downward along the second side of the chassis 4, and is then discharged from the third heat dissipation hole array 9.

[0028] The inverted "Y"-shaped air duct can dissipate heat for components with high heat generation inside the chassis 4 in a targeted manner, and dissipate heat for components located below the receiver board 3; the heat dissipation fan 6 on the first side of the chassis 4 of this embodiment only uses one fan with an air volume of 19㎡ / s, and the heat dissipation fan 6 on the second side of the chassis 4 also only uses two fans with an air volume of 19㎡ / s; compared with the one 20㎡ / s and two 30㎡ / s fans included in the traditional spread spectrum receiver cooling system, since the air duct design of this solution has a more reasonable air flow orientation, the heat dissipation fan 6 with a small air volume can also meet the heat dissipation requirements, thereby reducing the heat dissipation energy consumption. In addition, since this solution only takes in air through the second heat dissipation hole array 8, and the first heat dissipation hole array 7 and the third heat dissipation hole array 9 are only responsible for exhausting air, the other parts of the chassis 4 will be higher than the external air pressure, which can prevent dust from entering. To further prevent the entry of dust, the second heat dissipation hole array 8 is covered with a filter in this embodiment.

[0029] In addition, the present embodiment also provides a waterproof design for the chassis 4, as follows:

[0030] See also Figure 4 and Figure 7 As shown, in this embodiment, a rain cover 10 is provided on the front cover of the chassis 4. The top and bottom sides of the rain cover 10 have 45° bevel angles 11, which can effectively prevent rainwater from entering the interior of the chassis 4. In addition, a wiring space 12 is reserved between the bevel angle 11 at the bottom of the rain cover 10 and the bottom of the chassis 4, which is convenient for wiring between the interfaces of the main board 1 and the receiver board 3, as well as connecting external devices; the bevel angle 11 at the top of the rain cover 10 reserves an air intake space for the top of the chassis 4.

[0031] See also Figure 6 As shown, a bracket 13 is provided on the back of the chassis 4, and the bracket 13 extends toward the back of the chassis 4. The chassis 4 is supported on the ground by the bracket 13 to prevent water from entering the chassis 4. In addition, a handle 14 is provided on the front of the bracket 13 to facilitate the transportation of the chassis 4. Based on the above waterproof design, the spread spectrum tracking receiver provided in this embodiment has an IP52 waterproof rating, which effectively prevents the components inside the chassis 4 from being damp.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
