Description

Technical Field

[0001] This utility model relates to the field of mixer module housing technology, specifically to a mixer module housing that facilitates heat dissipation. Background Technology

[0002] Frequency mixing refers to the process of transforming a signal from one frequency to another; its essence is a linear shift of the frequency spectrum. In a superheterodyne receiver, the purpose of mixing is to ensure that the receiver achieves high sensitivity, sufficient amplification, and an appropriate passband, while also maintaining stable operation. A mixing circuit consists of three components: a local oscillator, nonlinear devices, and a bandpass filter. Due to the action of nonlinear components (such as diodes, transistors, and field-effect transistors), many combined frequency components are generated during the mixing process: pfL ± qfS. Generally, only fI = fLfS or fI = fSfL satisfies the desired result. The former generates the intermediate frequency (IF) in a high-difference mixing manner, while the latter is called low-difference mixing. Here, the series of combined frequency components generated during mixing are filtered by a bandpass filter to select the appropriate IF, while other frequency components are suppressed.

[0003] However, the existing mixer module housing still has some shortcomings. For example, heat dissipation is required when using the mixer module housing. However, the heat sink of the traditional mixer module housing often generates a lot of dust inside during use, and the heat sink needs to be cleaned. The existing heat sink cannot be moved at will, which is not conducive to cleaning the heat sink. Therefore, the existing technology needs to be improved. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] In this technical solution, a mixer module housing that facilitates heat dissipation includes a mixer module housing 1. A mixer module is assembled inside the mixer module housing 1. An exhaust vent 5 is opened at the top of the mixer module housing 1, and a cooling fan assembly 9 is assembled inside the exhaust vent 5. A support frame 6 is assembled inside the exhaust vent 5, and a heat dissipation and dustproof mesh is assembled inside the support frame 6. Fixing blocks 7 are installed on both side walls of the support frame 6. Fixing grooves 8 are opened on both side walls of the mixer module housing 1, and the fixing blocks 7 are installed in the fixing grooves 8. A storage cavity 12 is opened on the side wall of the fixing block 7, and a spring 11 is installed inside the storage cavity 12. A limiting plate 10 is installed at the end of the spring 11. A plug rod 15 is installed on the side wall of the limiting plate 10, and an insertion hole 14 is opened on the side wall of the fixing groove 8, into which the plug rod 15 is inserted.

[0024] In this technical solution, heat is removed through the exhaust vent 5 and air cooling is achieved through the cooling fan assembly 9. Dust is prevented by the cooling dustproof net 13 set at the exhaust vent 5. During installation, the fixing block 7 can be installed into the fixing groove 8 to install the bearing frame 6. The insertion rod 15 is inserted into the insertion hole 14 to fix the fixing block 7 in the fixing groove 8.

[0025] In some technical solutions, the outside of the insertion rod 15 is fitted with rubber pads a19 and b18, and both rubber pads a19 and b18 are set in the fixing groove 8. A rubber block 16 is installed on the side wall of rubber pad a19 facing rubber pad b18.

[0026] In this technical solution, the outer diameters of rubber pads a 19 and b 18 are both larger than the inner diameter of the socket 14, thereby sealing the gap in the socket 14 after the plug rod 15 is inserted into the socket 14.

[0027] In some technical solutions, the end of the insertion rod 15 is provided with an arc surface 17;

[0028] In this technical solution, the arc surface 17 facilitates the insertion of the insertion rod 15 into the insertion hole 14.

[0029] In some technical solutions, the cooling fan assembly 9 includes a fan frame 917 installed inside the exhaust port 5. A center seat 911 is installed in the middle section of the fan frame 917. Blades 912 are installed around the center seat 911. A reinforcing rib 914 is installed at the end edge of the blade 912. A raised reinforcing rib 914 is formed from one end 913 to the other end 915 of the reinforcing rib 914 from low to high. One end 913 of the reinforcing rib 914 extends beyond one end of the end edge of the blade 912. The beginning of the blade 912 is provided with a chamfer 916. The blade 912 is inclined.

[0030] In this technical solution, there are one or more reinforcing ribs 914, which can be raised or concave. The reinforcing ribs can increase the stability of the fan blades, thereby increasing the air volume of the fan blades, reducing the resistance of the incoming air, and reducing the fan noise. The blade body 912 is inclined to enhance the cutting airflow.

[0031] In some technical solutions, the bottom of the mixing module housing 1 is equipped with an air inlet pipe 2, and the end of the air inlet pipe 2 is equipped with a bearing ring 3.

[0032] In this technical solution, the air inlet duct 2 is a flexible telescopic hose, which is then placed on the server that needs heat dissipation.

[0033] In some technical solutions, fixing plates 4 are installed on both outer walls of the mixing module housing 1;

[0034] In this technical solution, the mixer module housing 1 is installed.

[0035] In some technical solutions, the mixer module housing consists of two down-conversion receiving channels. The down-conversion receiving channel includes a low-noise amplifier unit, a mixer unit, a local oscillator unit, and a gating filter unit. The antenna echo signal is processed by the low-noise amplifier unit and then sent to the mixer unit. The received signal with modulation information is multiplied with the input signal of the local oscillator unit to obtain the aliased signal after linear spectrum shift. Finally, the intermediate frequency signal with the required bandwidth is obtained through the gating filter unit.

[0036] In this technical solution, the model and working principle of the mixer module housing 1 are the same as those in patent number CN202311334560.6.

[0037] Working principle: When in use, the mixer module housing 1 can be installed on the server, and then the carrier block 6 with the heat dissipation and dustproof mesh 13 can be installed into the exhaust port 5. The fixing block 7 can be installed into the fixing groove 8. During installation, the insertion rod 15 is inserted into the storage cavity 12 through the spring 11. Then, after the fixing block 7 is inserted into the fixing groove 8, the insertion rod 15 is inserted into the insertion hole 14 through the spring 11, thereby completing the installation.
