Abstract
Description
Technical Field
[0001] This utility model relates to the field of acoustic and thermal detectors, specifically a convenient acoustic and thermal detector with heat dissipation. Background Technology
[0002] With the continuous development of acoustic thermal detector technology, its functions are becoming increasingly diversified. To meet the demand for portability, the size of the instruments is gradually being reduced. However, this diversification of functions leads to increased power consumption and consequently, increased heat generation during operation. Especially when used in high-temperature environments, the performance of the equipment will decrease. Therefore, how to effectively dissipate heat from acoustic thermal detectors has become a key factor affecting product performance and user experience.
[0003] In existing technologies, heat dissipation for acoustic thermal detectors mainly relies on ventilation holes on the outer wall of the casing containing the circuit board. However, acoustic thermal detectors are typically designed to be compact, making it difficult to accommodate sufficient heat dissipation devices within the limited space. Furthermore, their complex internal structure may obstruct airflow. If the equipment generates a large amount of heat under high-temperature and high-load conditions, and this heat cannot be dissipated in time, it will cause the equipment to overheat and malfunction, affecting its stability and reliability.
[0004] Therefore, this invention provides a convenient heat dissipation acoustic-thermal detector to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects
[0015] This convenient heat dissipation acoustic-thermal detector, through the setting of heat sinks, air ducts, and dustproof mechanisms, separates the FPGA chip on the array probe panel and the ARM processor chip on the instrument panel via air ducts, increasing the heat dissipation area between the two chips. Furthermore, by constructing air ducts between the grille holes on both sides, airflow is guided through the grille holes to enhance the heat dissipation effect. At the same time, thanks to the dustproof mechanism, the grille holes can be covered by baffles when the acoustic-thermal detector is not in use, reducing dust entry. During normal use, the baffles can be opened when the device is powered on, ensuring the normal use of the grille holes and increasing the practicality of the device. Attached Figure Description

[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] This utility model provides a convenient heat dissipation acoustic-thermal detector, such as... Figure 1-4 As shown, the acoustic thermal detector includes a housing 1 and an acoustic array assembly 2 disposed on the side of the housing 1. A display screen 3 is disposed at the end of the housing 1 away from the acoustic array assembly 2. An FPGA chip 5 adapted to the acoustic array assembly 2 is disposed on the inner wall of the housing 1. An ARM processor chip 6 corresponding to the display screen 3 is disposed at a position symmetrical to the FPGA chip 5 on the inner wall of the housing 1. Heat sinks 8 are fixedly installed on the sides opposite to the FPGA chip 5 and the ARM processor chip 6. Grille holes 7 corresponding to the heat sinks 8 are opened on both outer walls of the housing 1. An air duct 9 is disposed inside the housing 1 between the two heat sinks 8. A connecting frame 10 is fixedly installed on the outer wall of the housing 1 at the position of the grille hole 7. A dustproof mechanism is disposed on the connecting frame 10.
[0023] In use, the FPGA chip 5 on the array probe panel of the acoustic array assembly 2 of the acoustic thermal detector and the ARM processor chip 6 on the acoustic thermal detector panel are separated by the air duct 9. Heat sinks 8 are set on the FPGA chip 5 and the ARM processor chip 6. By increasing the surface area, heat is quickly absorbed and transferred to the surrounding air, thereby accelerating the heat dissipation process and effectively reducing the internal temperature of the equipment. In order to further improve the heat dissipation effect of this structure, the air duct 9 is set between the heat sinks 8. The use of the grille holes 7 increases the airflow and further improves the heat dissipation effect.
[0024] Specifically, the grille holes 7 and the air duct 9 are arranged opposite each other; the grille holes 7 and the air duct 9 on both sides are arranged opposite each other on the same plane, which makes it easier for heat to be dissipated from the grille holes 7 through the air duct 9, increasing airflow and improving heat dissipation.
[0025] Furthermore, the heat sink 8 is made of metal, ensuring better heat transfer.
[0026] More specifically, the dustproof mechanism includes a number of baffles 111 arranged in a linear array and rotatably mounted on the inner wall of the connecting frame 10 via a rotating shaft, a number of rotating wheels 112 arranged in a linear array and rotatably mounted on the side of the connecting frame 10, and a number of connecting rods 113 hinged between two rotating wheels 112. The end of the rotating shaft passes through the connecting frame 10 and is fixedly connected to the side of the rotating wheel 112. An operating wheel 114 is rotatably mounted on the side of the connecting frame 10 away from the rotating wheel 112, and the rotating end of the operating wheel 114 is fixedly connected to the end of one of the rotating shafts. When the acoustic thermal detector is in normal use, the position of the baffle 111 is as shown in the figure. At this time, the gas can flow through the baffle 111, and the grid hole 7 can communicate with the outside. When storing the acoustic thermal detector after use, the operating wheel 114 can be rotated manually to drive the rotating shaft to rotate, so that the baffle 111 rotates to a vertical position to block the connecting frame 10, thereby isolating the grid hole 7 from the outside and preventing dust from entering the housing 1 during storage. When using it again, the operating wheel 114 can be reversed to drive the baffle 111 to a horizontal position to expose the grid hole 7 for use.
[0027] Furthermore, one end of the baffle 111 is provided with an overlap groove 115, and the end of the baffle 111 away from the overlap groove 115 is fixedly installed with an overlap strip 116 that is compatible with the overlap groove 115; when the baffle 111 is rotated to the vertical position, two adjacent baffles 111 can contact each other through the overlap groove 115 and the overlap strip 116, so that the gap between the baffles 111 is blocked, effectively reducing the entry of dust.
[0028] Furthermore, a handle 4 is fixedly installed on the bottom surface of the housing 1, and the outer wall of the handle 4 is provided with anti-slip texture; the housing 1 can be gripped through the handle 4, and the anti-slip texture makes the grip more secure.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
