Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-2, a fiber grating demodulator case, including installation casing 1 and heat exchanger 2, heat exchanger 2 covers the one end of installation casing 1, install heat radiation fins 21 and heat dissipation fan 22 in the heat exchanger 2, and the outer wall of heat exchanger 2 is provided with air intake 23 and air outlet 24, heat dissipation fan 22 covers air intake 23, and the bottom of installation casing 1 is provided with a plurality of heat conduction limiting plates 11, is provided with heat pipe 12 between heat conduction limiting plate 11 and the heat radiation fins 21. In this scheme, each component in the fiber grating demodulator is connected with heat conduction limiting plate 11, and when the fiber grating demodulator worked, the heat that each component in the fiber grating demodulator produced can transmit heat conduction limiting plate 11 to, then the heat on the heat conduction limiting plate 11 reachs heat radiation fins 21 along heat pipe 12 again. At this time, the heat radiating fan 22 starts to operate, and introduces the external air into the heat radiating cover 2 through the air inlet 23. The external air having a relatively low temperature exchanges heat with the radiator fins 21, that is, the external air cools the radiator fins 21. After the heat exchange is completed, the air inside the heat dissipation cover 2 carries heat from the air outlet 24 to the outside. Because no electronic component is arranged in the heat dissipation cover 2, the air inlet 23 and the air outlet 24 of the heat dissipation cover 2 may not be sealed, so that the air flow rate entering the heat dissipation cover 2 from the air inlet 23 is relatively high, thereby rapidly taking away the heat on the heat dissipation fins 21 and completing the heat dissipation of each component inside the fiber bragg grating demodulator. The installation housing 1 can also be completely sealed, so that the external suspended particles are directly isolated.
One part of the heat pipe 12 is located between the heat-conducting limiting plate 11 and the mounting case 1, and the other part of the heat pipe 12 is in heat-conducting connection with the heat-dissipating fins 21. When the heat conduction limiting plate 11 is installed, the heat conduction pipe 12 is extruded and fixed between the heat conduction limiting plate 11 and the installation shell 1, so that a contact point exists between the heat conduction pipe 12 and the heat conduction limiting plate 11, and heat on the heat conduction limiting plate 11 and the installation shell 1 can reach the heat dissipation fins 21 along the heat conduction pipe 12. Preferably, the heat conducting pipe 12 is a U-shaped heat pipe, the middle area of the U-shaped heat pipe is located between the heat conducting limiting plate 11 and the installation shell 1, and both ends of the U-shaped heat pipe are connected with the heat radiating fins 21 in a heat conducting manner. This design allows both ends of the heat conductive pipe 12 to transfer heat, thereby increasing the heat dissipation rate. Further, a heat conduction layer 13 is arranged between the heat conduction limiting plate 11 and the heat conduction pipe 12. The heat conduction layer 13 fills the gap between the heat conduction pipe 12 and the heat conduction limiting plate 11, so as to increase the contact area between the two, and further increase the heat transfer speed.
In this embodiment, the heat-conducting layer 12 may be selected from various materials, such as a heat-conducting pad or a glue formed by curing a heat-conducting glue.
The air outlet 24 is located on the side wall of the heat dissipation cover 2, the air inlet 23 is located at one end of the heat dissipation cover 2 far away from the mounting housing 1, and the heat dissipation fan 22 is located between the air inlet 23 and the heat dissipation fins 21. This scheme adopts the formula forced air cooling heat dissipation of pushing down, and heat dissipation fan 22 guides the air to flow towards heat radiation fins 21 promptly, and then hot-air can flow from the air outlet 24 of heat exchanger 2 side.
As shown in fig. 3, the heat dissipation fins 21 include a plurality of heat dissipation fins 211, and the heat dissipation fins 211 correspond to the heat conduction limiting plates 11 one to one. The heating values of the components inside the fiber grating demodulator are different, and if the same heat dissipation fin 21 is used in common, the heat dissipation effects of different components are different. For this reason, the heat sink fins 21 are divided into a plurality of heat sinks 211, and one heat sink 211 is responsible for heat dissipation only corresponding to the heat-conducting limiting plate 11, which makes the heat dissipation effect of each component to be the best.
A filter screen 25 is arranged between the heat dissipation fan 22 and the air inlet 23. Although the heat dissipation cover 2 may not be sealed, if the air inlet 23 is not provided with the filter net 25, this may cause the entry of various foreign matters such as flying insects and sand, which may cause the damage of the heat dissipation fins 21. Therefore, a filter screen 25 is required at the air inlet 23. The filter screen 25 has a large aperture to prevent flying insects and sand from entering while reducing air blockage.
As shown in fig. 4 to 5, the heat dissipation capability of the heat dissipation cover 2 is limited, so that each element inside the fiber grating demodulator still has the problem of overheating when working for a long time. Therefore, the mounting shell 1 comprises an air inlet channel 14, an air outlet channel 15, a dust screen 16 and a suction fan 17, wherein the air inlet channel 14 and the air outlet channel 15 are arranged oppositely, the suction fan 17 covers the air outlet channel 15, and the dust screen 16 covers the air inlet channel 14. The purpose of the above design is to reduce heat build-up inside the mounting housing 1. Because the main heat generated during the operation of the fiber grating demodulator is radiated by the heat radiation cover 2, if the installation shell 1 is completely sealed, a small amount of heat is still accumulated in the installation shell 1, thereby affecting the working efficiency of the internal elements of the fiber grating demodulator. Therefore, the installation shell 1 introduces an air inlet channel 14, an air outlet channel 15, a dust screen 16 and an exhaust fan 17, wherein the aperture of the dust screen 16 needs to be small enough to reduce the suspended particles from entering the fiber grating demodulator. Although the small aperture of the dust screen 16 affects the air flow speed inside the fiber grating demodulator, the air flow speed inside the fiber grating demodulator is acceptable because the heat is mainly dissipated by the heat dissipation cover 2.
In order to conveniently take the fiber grating demodulator, the mounting case 1 further includes a first handle 111 and a second handle 112, and the air inlet 23 is located between the first handle 111 and the second handle 112.
The mounting case 1 further includes a first connecting plate 113 and a second connecting plate 114, and the first handle 111 and the second handle 112 are located between the first connecting plate 113 and the second connecting plate 114. The first connecting plate 113 and the second connecting plate 114 are used for connecting with other structures, so that the fiber grating demodulator can be fixed at a certain position for use.
To sum up, the beneficial effect of this device does: firstly in order to solve the relatively poor problem of fiber grating demodulation appearance heat-sinking capability among the prior art, heat exchanger 2, heat conduction limiting plate 11, heat pipe 12 have been introduced to this scheme, and each component in the fiber grating demodulation appearance is connected with heat conduction limiting plate 11, and the heat that each component produced this moment will transmit heat pipe 12 through heat conduction limiting plate 11, then transmits heat radiation fins 21 by heat pipe 12, accomplishes the radiating process. In the above process, the mounting case 1 itself can be eliminated from the heat dissipating device, thereby increasing the sealing degree of the mounting case 1. The second is that the heat pipe 12 is a U-shaped heat pipe, so that the middle region of the heat pipe 12 receives heat from the heat conduction limiting plate 11, and the two ends of the heat pipe 12 transmit heat to the heat dissipation fins 21, thereby increasing the transmission speed of heat. Thirdly, the heat dissipation fins 21 comprise a plurality of heat dissipation fins 211, and the heat dissipation fins 211 correspond to the heat conduction limiting plates 11 one by one, which not only increases the overall heat dissipation area, but also enables heat generated by different components to be dissipated quickly. Fourthly, the installation shell 1 is provided with an air inlet channel 14, an air outlet channel 15, a dust screen 16 and an exhaust fan 17, and the whole heat dissipation speed is further accelerated.
The present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes without creative labor from the above conception, and all the changes fall within the protection scope of the present invention.
