Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
Research shows that the wave recorder can cause internal heating after being used for a long time, and most of the existing wave recorders do not have a heat dissipation function. In order to solve the problem of heat generation, a motor and a fan are usually installed inside the recorder. Although this approach can reduce the temperature to some extent, it also causes the following problems:
1. the motor can also generate heat when working for a long time, and the heat of the motor can be gathered in the wave recorder, so that the heat dissipation function of the wave recorder is reduced;
2. the motor and the fan occupy the internal space of the wave recorder, and the structural complexity of the wave recorder is increased;
3. the motor and the fan are arranged in the machine body, so that the maintenance is inconvenient, and once the motor fails, the whole wave recorder needs to be disassembled, so that the machine is very inconvenient.
In order to solve the problems, the invention provides an air-cooled wave recorder and a method. As shown in fig. 1 to 5, the air-cooled oscillograph provided by the present invention includes: the air-conditioning unit comprises a box body 10, an air outlet 11, an air inlet 12, a shielding part 14, an air collecting mechanism 20, a mechanism main body 21, an air cavity 211, an air outlet through hole 212, a bolt 213, a driving motor 221, a transmission shaft 222, a first channel 2221, an air collecting unit 23, an air collecting piece 231, a connecting piece 232, a second channel 2321, an elastic air inducing piece 24, an annular blocking part 241 and a filtering device 25.
The air-cooled oscillograph of the invention is explained in detail with the attached drawings: the invention provides an air-cooled wave recorder which comprises a box body 10 and a wind collecting mechanism 20.
Specifically, referring to fig. 1, a plurality of electronic components are disposed in the housing 10 to meet the working requirements of the wave recorder. The case 10 mainly functions to protect the internal electronic components thereof. Prevent the internal electronic components from being damaged due to collision in the transportation and working processes. Meanwhile, the box body 10 can also play a dustproof role, so that the problem that heat on the electronic components is difficult to dissipate due to the fact that a large amount of dust is accumulated on the electronic components is avoided. It is because of the arrangement of the casing 10 that the heat emitted from the internal electronic components is accumulated in the casing 10, resulting in difficulty in emission. For this purpose, at least one air inlet 12 and at least one air outlet 11 are provided on the housing 10. Air is introduced through the air inlet 12, circulates in the case 10 and discharges heat emitted from the electronic components through the air outlet 11. However, the passive heat dissipation method causes low heat dissipation efficiency of the wave recorder, and needs to be optimized.
Further, the heat dissipation efficiency of the wave recorder is improved by adopting the external wind collecting mechanism 20. Specifically, referring to fig. 2 and 3, the wind-collecting mechanism 20 includes a mechanism main body 21 detachably connected to the case 10 along the outer side of the case 10, a driving unit fixed to the mechanism main body 21, and at least one wind-collecting unit 23 connected to the driving unit. Wherein an air chamber 211 is formed in the mechanism body 21. An air outlet hole 212 corresponding to the air inlet 12 is formed at one side of the air cavity 211. The wind-collecting unit 23 is driven to move by the driving unit and introduces external air into the air chamber 211. Then, the air in the air cavity 211 is introduced into the interior of the box body 10 through the air inlet 12 for air cooling.
Referring to fig. 3, the driving unit in this embodiment includes a driving motor 221 and a driving shaft 222. The driving motor 221 is fixedly connected to one end of the mechanism body 21. Specifically, the driving motor 221 is fixedly connected to the bottom of the mechanism body 21, and an output end of the driving motor 221 extends upward along the axis of the mechanism body 21 into the air cavity 211 and is fixedly connected to the bottom end of the transmission shaft 222. The transmission shaft 222 is disposed coaxially with an output shaft of the driving motor 221. The top end of the transmission shaft 222 extends upwards out of the air cavity 211 and then is fixedly connected with the wind collection unit 23. In addition, a first passage 2221 communicating with the air chamber 211 is formed in the interior of the drive shaft 222 in the axial direction. A plurality of air holes can be formed on the side wall of the transmission to realize the communication between the first passage 2221 and the air cavity 211.
The number of the wind collection units 23 in the present embodiment is set to three. The three wind collecting units 23 are uniformly arranged in the circumferential direction of the drive shaft 222. Each wind-collecting unit 23 includes a wind-collecting member 231 and a connecting member 232. Wherein, the wind-collecting member 231 has at least one concave surface to collect air. For example, the wind scoops 231 may be designed in a hemispherical structure. The concave surface of the wind scooping member 231 having such a structure is smooth, so that air can be collected and concentrated maximally. The situation that the air turns back due to the edge of the concave surface is avoided. One end of the connecting member 232 is connected to the wind-collecting member 231, and the other end thereof is connected to the driving shaft 222. Meanwhile, the inside of the connection member 232 is hollow to form a second passage 2321 having one end extended to the first passage 2221 and the other end extended to the concave surface. When the driving motor 221 drives the wind collection unit 23 to rotate circumferentially through the transmission shaft 222, the wind collection member 231 collects air and introduces the air into the air chamber 211 through the second passage 2321 and the first passage 2221 in sequence.
Among the prior art, when making the air flow through motor drive fan rotation, no matter how the motor sets up can make the heat that the motor produced absorb by the air that flows, under this kind of condition, must lead to the temperature of air to rise, and then reduce the radiating efficiency. For example, the motor is disposed at the rear side of the fan, and when the fan rotates, air at the rear side of the fan is guided by the fan to move towards one side of the fan, so that heat of the motor is used for cooling along with flowing air. When the motor is disposed at the front side of the fan, the flowing air generated by the rotation of the fan moves to one side of the motor, which also causes the heat of the motor to be used for cooling along with the flowing air. Therefore, the mode of cooling through the rotation of motor drive fan can lead to cooling efficiency not high. The present invention completely avoids this: on the other hand, the driving motor 221 is externally installed to the cabinet 10, so that heat of the driving motor 221 does not affect the inside of the cabinet 10. On the other hand, the air collected by the wind collecting element 231 directly passes through the second channel 2321, the first channel 2221 and the air cavity 211 until being introduced into the box body 10, and the directional guidance enables the air for cooling not to be affected by the heat generated by the driving motor 221; meanwhile, the air is guided directionally to carry out air cooling, so that the introduced air cannot escape, and the cooling and heat dissipation efficiency is improved. When the fan is adopted, the flowing air is diffused to the periphery, so that a large part of air escapes, and the cooling and heat dissipation efficiency is reduced.
In a further embodiment, the mechanism body 21 is provided with pins 213 at two sides of the air outlet hole 212. Meanwhile, the box 10 is provided with slots (not shown) respectively at both sides of the air inlet 12, which are adapted to the pins 213. Specifically, the cross section of the plug 213 and the cross section of the slot are of a matched dovetail structure, so that the slot can provide horizontal limitation while guiding the plug 213 in the vertical direction, so as to detachably mount the mechanism body 21 of the wind collection mechanism 20 on the outer side of the box 10. In addition, one end of the slot is also provided with a limiting part which can be the closed end at the bottom of the slot. Through the degree of depth that spacing portion control bolt 213 inserted the slot, insert and with along the slot when bolt 213 contradicts spacing portion, air-out through-hole 212 with air intake 12 is relative, and then makes the air of air-out through-hole 212 smoothly get into the inside of box 10 from air intake 12, and can not blockked to ensure the flow of the air of introducing, promote the efficiency of forced air cooling.
Although the outlet vent 212 is opposite to the inlet 12 to ensure the air flow. However, since the mechanism main body 21 is detachably connected to the casing 10, a certain gap is left between the mechanism main body 21 and the casing 10 for the convenience of detachment. The structure inevitably leads to the escape of air, and reduces the flow rate of the introduced air. In a further embodiment, with reference to fig. 2 and 4, an elastic air inducing member 24 with a hollow interior is disposed at the air outlet hole 212. Specifically, the elastic air inducing member 24 may be an elastic hose which is extensible in its own axial direction. One end of the elastic hose is fixedly connected with the outer wall of the mechanism main body 21. When the wind collecting mechanism 20 is mounted on the box body 10, the other end of the elastic hose abuts against the outer wall of the box body 10 at the wind inlet 12. The elastic air inducing piece 24 eliminates the gap between the mechanism main body 21 and the box body 10, so that the air tightness between the mechanism main body 21 and the box body 10 is improved, and the flow rate of the introduced air is further ensured.
When the wind-collecting mechanism 20 is installed, the elastic wind-inducing pieces 24 are pressed to deform. When the elastic air inducing piece 24 deforms due to squeezing, the air outlet hole 212 may shift relative to the air inlet 12, and the elastic air inducing piece 24 may block the air inlet 12. In a further embodiment, in conjunction with fig. 4, the outer wall of the elastic wind-inducing member 24 is formed with an annular stopper 241 near the free end thereof by a predetermined distance. Moreover, the size of the elastic induced draft piece 24 is slightly smaller than that of the air inlet 12, and the size of the annular blocking portion 241 is slightly larger than that of the air inlet 12. The dimensions referred to herein are not limited to the sides of polygonal structures, the radii or diameters of circular structures. So that the free end of the elastic wind inducing member 24 can be inserted into the wind inlet 12 while the annular stopper 241 interferes with the outer wall of the case 10. Thereby avoiding the situation that the elastic air inducing piece 24 blocks the air inlet 12 due to the transverse sliding generated when the elastic air inducing piece 24 is extruded and deformed; meanwhile, the elastic induced draft pieces 24 are extruded and deformed to make the annular blocking part 241 tightly contact with the outer wall of the box body 10, so that the air tightness is improved.
Since the wave recorder is often used in a place with much dust such as a power plant or a power station, in the environment, dust enters the inside of the case 10 and deposits on the electronic components, and further, heat generated by the electronic components is difficult to dissipate. The long-term use can cause the temperature of electronic components to be too high, thereby influencing the service life of the recorder. This portion of dust enters the interior of the housing 10 primarily in two ways: one is dropped into the box body 10 through the air outlet 11; the other is introduced into the case 10 through the wind collection mechanism 20.
In a further embodiment, with reference to fig. 5, a shielding portion 14 is provided at the outlet 11 of the box 10. The shielding portion 14 is disposed opposite to the air outlet 11. Specifically, one side of the shielding portion 14 is fixedly connected to the outer wall of the box 10, and one side of the shielding portion 14 is far away from the outer wall of the box 10 and forms an airflow channel perpendicular to the air outlet direction of the air outlet 11. The air discharged from the air outlet 11 is discharged along the airflow path, and the external dust is blocked by the blocking portion and does not directly fall into the interior of the box 10 through the air outlet 11. Further, a filter device 25 is provided in the air chamber 211. The filter device 25 is annularly provided to the drive shaft 222. Specifically, the filter device 25 may employ a filter screen having a cylindrical structure. The filter unit 25 filters the air introduced into the air chamber 211 to remove most of the dust therein, thereby reducing the deposition of the dust in the cabinet 10.
The long-term use of the wind-collecting mechanism 20 can cause a large amount of dust to be deposited on the filtering device 25, thereby reducing the air flow rate of the air cooling and reducing the cooling effect. The mechanism body 21 is designed to be detachable from a first mechanism body and a second mechanism body (not shown) in order to facilitate cleaning of the filter device 25. By detaching the first mechanism body and the second mechanism body, the filter device 25 can be cleaned easily. The filter effect in the time of can promoting at every turn to use can ensure air mass flow again and be sufficient to realize rapid cooling. The first mechanism body and the second mechanism body in this embodiment may be two parts that are screwed vertically to the mechanism body 21, or may be two parts that are engaged with each other in the left-right direction. In the case of two parts that are screwed up and down, the connecting member 232 and the transmission shaft 222 must be fixedly connected by a detachable connection, such as a screw connection, so that the upper and lower parts of the mechanism body 21 can be separated in the axial direction.
The working principle is as follows: when the oscillograph needs to be cooled, the wind collecting mechanism 20 is firstly installed on the outer side of the box body 10: inserting the bolt 213 on the mechanism main body 21 of the wind collection mechanism 20 along the slot until the bolt 213 abuts against the limiting part, and at this time, the wind outlet through hole 212 is opposite to the wind inlet 12, and the gap between the mechanism main body 21 and the box body 10 is eliminated through the elastic wind inducing piece 24; then, the driving motor 221 is started to drive the driving motor 221 to drive the wind collection unit 23 to rotate through the transmission shaft 222, the wind collection piece 231 of the wind collection unit 23 collects air in the rotating process, the air is introduced into the air cavity 211 through the second channel 2321 and the first channel 2221 in sequence, the introduced air is filtered by the filtering device 25, the filtered air is introduced into the box body 10 through the air inlet 12 and circulates in the box body 10, and finally the air is discharged from the air outlet 11 to take heat out of the box body 10. In this process, heat generated by the operation of the driving motor 221 is directly radiated outside the cabinet 10. When the filter device 25 needs to be cleaned, the wind collection mechanism 20 is taken down from the box body 10, and then the first mechanism body and the second mechanism body are separated to clean the filter device 25.
