Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic equipment manufacturing technology, and in particular to a W-band power amplifier with heat dissipation function. Background Technology
[0002] W-band power amplifiers are an important component of wireless communication systems and are widely used in fields such as electronic communication, radar, and drones. The main function of a W-band power amplifier is to amplify the power of the input signal in order to drive the load to work normally. In this process, the amplifier needs to convert the DC energy of the power supply into AC energy output. However, since the energy conversion efficiency cannot reach 100%, some energy will be lost in the form of heat, which leads to the heating phenomenon of the power amplifier.
[0003] However, after prolonged use, the heat sink of a traditional W-band power amplifier may accumulate dust, dirt, or other impurities, forming a thermal resistance layer on its surface. This leads to poor heat transfer and reduced heat dissipation efficiency. If a heat sink with accumulated dust, dirt, or other impurities is used in the electronic equipment of a power amplifier for a long time, the circuit board may age and be damaged due to high temperature.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Example 1
[0030] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a W-band power amplifier with heat dissipation function. The W-band power amplifier with heat dissipation function includes a main component 100, including a sealing shell 101, a circuit board 102 and a heating element 103. The heating element 103 is soldered to the surface of the circuit board 102, and the circuit board 102 is fixed inside the sealing shell 101.
[0031] By setting the sealing shell 101, the circuit board 102 and the heating element 103 can be protected, preventing external environmental interference from affecting the circuit board 102 and the heating element 103.
[0032] The heat dissipation assembly 200 is disposed on one side of the heat-generating element 103 and includes a heat dissipation component 201. The heat dissipation component 201 includes a heat-conducting sheet 201a. The heat-conducting sheet 201a is attached to one side of the heat-generating element 103, and a heat dissipation sheet 201b is attached to the other side of the heat-conducting sheet 201a.
[0033] By using a heat-conducting sheet 201a to conduct the heat generated by the heating element 103 to the heat sink 201b, the heat sink 201b can quickly dissipate heat, thus ensuring the normal operation of the heating element 103 on the circuit board 102.
[0034] Specifically, the heat sink 201 also includes a first limiting strip 201c, which is fixed to the end of the heat sink 201b. Both ends of the first limiting strip 201c are fixed with annular seats 201d, and a second limiting strip 201e is fixed to one side of the annular seat 201d. A circular groove 201d-1 is opened in the annular seat 201d.
[0035] The first limiting strip 201c and the second limiting strip 201e are fixed by the annular seats 201d at both ends, so that a groove is formed between the first limiting strip 201c and the second limiting strip 201e, allowing other components to slide. At the same time, the first limiting strip 201c is fixed to the heat sink 201b, so that the annular seats 201d and the second limiting strip 201e are fixed in position. The circular slot 201d-1 is used to provide rotation space for the components therein.
[0036] Specifically, there are four annular seats 201d, and two first limit bars 201c and two second limit bars 201e.
[0037] The first limiting bar 201c and the second limiting bar 201e are used in two groups, upper and lower, with each group including one first limiting bar 201c, one second limiting bar 201e, and two annular seats 201d.
[0038] Specifically, the heat dissipation assembly 200 also includes a cleaning component 202, which includes a sliding tube 202a. Square sections 202b are fixed at both ends of the sliding tube 202a, and the square sections 202b slide between the first limiting strip 201c and the second limiting strip 201e.
[0039] The distance between the first limiting bar 201c and the second limiting bar 201e is fixed, which allows the square section 202b to slide parallel between the two without causing the square section 202b to rotate. This ensures that the sliding tube 202a will not rotate when it is between the first limiting bar 201c and the second limiting bar 201e.
[0040] Specifically, the cleaning component 202 also includes a cleaning column 202d, which is rotatable inside the sliding tube 202a. A cleaning strip 202e is fixed on the surface of the cleaning column 202d. A rotation slot 202a-1 is opened on the surface of the sliding tube 202a, and the cleaning strip 202e can rotate inside the rotation slot 202a-1. A torsion spring 202f is provided inside the square section 202b at the bottom of the sliding tube 202a. One end of the torsion spring 202f is fixedly connected to the inner wall of the square section 202b, and the other end is fixed to the surface of the cleaning column 202d.
[0041] A cleaning strip 202e is fixed to the surface of the cleaning column 202d. The cleaning strip 202e moves horizontally between the gaps of the heat sink 201b to scrape away dust accumulated over long-term use. The rotating slot 202a-1 on the surface of the sliding tube 202a allows the cleaning strip 202e to rotate, facilitating dust removal from its surface during pull-back. The torsion spring 202f connects the square joint 202b and the cleaning column 202d, allowing the cleaning strip 202e to return to its original position after being twisted during use.
[0042] Specifically, a fixed circular plate 202g is provided at the end of the cleaning column 202d. The fixed circular plate 202g is fixedly connected to the end of the cleaning column 202d, and a protrusion 202h is fixed on the surface of the fixed circular plate 202g.
[0043] The function of the fixed circular plate 202g is to prevent the sliding tube 202a from tilting during the sliding process, which would affect the cleaning effect. The protrusion 202h is used for manual pulling of the cleaning column 202d.
[0044] Example 2
[0045] Reference Figure 3 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0046] Specifically, the heat dissipation assembly 200 also includes a processing component 203, which is disposed on one side of the second limiting strip 201e. The processing component 203 includes a cleaning rod 203a, which is fixed to one side of the second limiting strip 201e. A small spring 203d is fixed on the surface of the cleaning rod. A fixing buckle 203b is also fixed on the surface of the cleaning rod 203a. A rotating groove 203b-1 is opened on the surface of the fixing buckle 203b. A stop bar 203c is rotatably connected to the surface of the fixing buckle 203b through the rotating groove 203b-1. The stop bar 203c is fixedly connected to one end of the small spring 203d.
[0047] The small spring 203d is in its normal state. The cleaning rod 203a is used to install the baffle 203c. Through the rotation of the fixing buckle 203b and the reset action of the small spring 203d, the cleaning rod 203a can pass smoothly during the back and forth pulling process, but the baffle 203c on the cleaning rod 203a will scrape out the dust remaining on the cleaning strip 202e.
[0048] Example 3
[0049] Reference Figure 2 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0050] Specifically, the sealing shell 101 has ventilation mesh holes 101-1 on its surface and a stretching groove 101-2 on its upper surface. The sliding tube 202a slides in the stretching groove 101-2.
[0051] The ventilation mesh 101-1 allows the hot air inside the sealing shell 101 to exchange with the outside air, and the stretch groove 101-2 limits the movement of the cleaning column 202d.
[0052] Specifically, a storage slot 101-3 is provided below the ventilation mesh 101-1, and a storage box 104 is slidably connected inside the storage slot 101-3.
[0053] Storage slot 101-3 is used to place storage box 104, which is used to collect and store fallen dust for easy cleaning.
[0054] Specifically, the surface of the sealing housing 101 is provided with an input port 105 and an output port 106.
[0055] The input signal is connected to the W-band power amplifier through input port 105 and then output through output port 106.
[0056] During use, when dust, dirt, or other impurities accumulate on the heat sink, the hand-held protrusion 202h is pushed along the stretching groove 101-2. At this time, under the action of the torsion spring 202f, the cleaning strip 202e is pushed towards the rotating slot 202a-1 side, preventing the cleaning strip 202e from deflecting and failing to clean the deep gaps of the heat sink 201b. Pulling the protrusion 202h back and forth pushes out the dust, dirt, or other impurities inside the heat sink 201b, causing the dust to fall into the storage box 104 below. After cleaning the heat sink 201b, the cleaning column 202d is pushed along the stretching groove 101-2 into the circular slot 201d-1 of the annular seat 201d on the other side. At this time, the circular slot 201d-1 can be a square section 20. The rotation of 2b provides space. At this time, rotating the protrusion 202h 90 degrees allows the cleaning strip 202e to contact the other side of the rotating slot 202a-1. At this time, pull back the protrusion 202h. After the sliding tube 202a passes the cleaning rod 203a, the cleaning strip 202e has rotated to the side of the baffle 203c. Continue to pull back, and the remaining dust and impurities on the cleaning strip 202e will be scraped off by the baffle 203c and fall into the storage box 104 below. When pulled back to the end, the square section 202b enters the rotating slot 202a-1 again. Rotate the protrusion 202h 90 degrees in the opposite direction to reset the cleaning strip 202e. Pull out the storage box 104, empty the dust, and put it back into the storage slot 101-3. The cleaning is complete.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
