Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of color sorters, in particular to a heat dissipation structure for halogen lamps and a color sorter with the same. Background Art

[0002] Halogen lamps have unique advantages in many application scenarios due to their simplicity, low cost, easy adjustment and control of brightness, good color rendering (Ra = 100), etc. However, when halogen lamps are applied in some occasions that require long-term stable operation or high-efficiency lighting, especially in the field of color sorters, their filaments are prone to fusing under high temperature for a long time, resulting in a relatively high failure rate, which is also one of the reasons for their relatively short service life.

[0003] In the production scenario of color sorters, it is usually necessary to dissipate heat from halogen lamps. The existing technical solutions for heat dissipation of halogen lamp cups mainly adopt air-cooled heat dissipation and heat sinks. Air-cooled heat dissipation has low heat dissipation efficiency, which easily leads to too high temperature of the lamp cup, baking and breaking the filter glass used in sets with it; and air-cooling requires an air-cooled heat dissipation cavity to be formed around the lamp to be dissipated, increasing the structural size and the difficulty of machine maintenance, and even being unable to be maintained in some occasions. Due to its huge heat dissipation structure, heat sinks have great design difficulty and are greatly limited in the application scenarios of color sorters. To sum up, the existing solutions for heat dissipation of halogen lamp cups have problems such as low heat dissipation efficiency, too large structural size, and great maintenance difficulty. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a heat dissipation structure for halogen lamps.

[0005] The utility model is realized by the following technical solutions: A heat dissipation structure for halogen lamps includes an aluminum plate, the aluminum plate is in a C-shaped structure, and left end caps and right end caps are respectively arranged at both ends of the aluminum plate;

[0006] A cooling mechanism, two symmetrical cavities are penetrated and opened on the aluminum plate, guiding mechanisms are respectively arranged on the left end cap and the right end cap, and the guiding mechanisms are respectively communicated with both ends of the cavity for the coolant to circulate, and a card slot for installing a halogen lamp cup is opened on the aluminum plate.

[0007] Through the above technical solutions, by setting the aluminum plate in a C-shaped structure, not only can multiple halogen lamp cups be stably installed, but also the cavities are symmetrically opened on the aluminum plate to cool the halogen lamp cups from the upper and lower sides, greatly improving the cooling efficiency.

[0008] As a further improvement of the above solution, the guiding mechanism includes a water pipe joint, a connection cavity, a fluid inlet, and a fluid outlet. The two water pipe joints are respectively arranged on the left end cover and the right end cover. The fluid inlets are respectively opened on the left end cover and the right end cover inside the water pipe joints. The connection cavities are respectively opened on the left end cover and the right end cover, and the connection cavity is communicated with the fluid inlet. The two fluid outlets are respectively opened on the opposite sides of the left end cover and the right end cover, and the fluid outlet is communicated with the connection cavity.

[0009] Through the above technical solution, by respectively installing the water pipe joints on the left end cover and the right end cover, the coolant in the water pipe can be guided to stably enter the connection cavity from the fluid inlet and then enter the aluminum plate for cooling operation.

[0010] As a further improvement of the above solution, a sealing ring is arranged between the cavity and the fluid outlet for sealing operation. Bolt holes are respectively opened on the left end cover and the right end cover, and threaded holes are opened on the aluminum plate. The threaded holes and the bolt holes can be mutually matched for fixing screws to fix.

[0011] Through the above technical solution, the arranged sealing ring can ensure the sealing performance of the direct installation of the aluminum plate with the left end cover and the right end cover respectively, prevent the coolant from flowing out from the gap between the fluid outlet and the cavity, protect the halogen lamp cup and ensure the stable circulation of the coolant at the same time.

[0012] As a further improvement of the above solution, two left - right mounting plates are fixed inside the aluminum plate, and a plurality of intermediate mounting plates are equidistantly arranged inside the aluminum plate between the two left - right mounting plates. A protective rubber strip is arranged between the left - right mounting plates and the intermediate mounting plates, and a filter glass is installed between the protective rubber strips.

[0013] Through the above technical solution, by fixing the filter glass between the left - right mounting plates and the intermediate mounting plates, the stability of the installation of the filter glass can be ensured. At the same time, the protective rubber strip is set to prevent the surface of the filter glass from being scratched.

[0014] As a further improvement of the above solution, fin strips are symmetrically fixed inside the aluminum plate.

[0015] Through the above technical solution, by arranging the fin strips, the distance of the coolant propagation in the cavity along the conductor can be extended to ensure the cooling effect.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] The present utility model uses the method of circulating coolant to dissipate heat from the halogen lamp, improves the heat dissipation efficiency, extends the service life of the halogen lamp, and reduces the overall machine cost; uses an aluminum profile with one or more cavities for heat dissipation, installs all accessories on this aluminum profile, reduces the structural size, and reduces the maintenance difficulty.

[0031] It should be noted that a halogen lamp driving board 5 is arranged on the aluminum plate 2, and the halogen lamp driving board 5 is used to control parameters such as the current of the infrared halogen lamp. A temperature sensor 6 is also arranged on the aluminum plate 2 and attached to the surface of the aluminum plate 2, which is a signal input source for indirectly detecting and monitoring the heat generation situation of the halogen lamp cup 4.

[0032] Cooling mechanism. Two symmetrical cavities 201 are penetrated through the aluminum plate 2. Guiding mechanisms are respectively arranged on the left end cover 1 and the right end cover 7, and the guiding mechanisms are respectively communicated with both ends of the cavity 201 to allow the coolant to circulate. A card slot 204 for installing the halogen lamp cup 4 is opened on the aluminum plate 2.

[0033] It should be noted that if the halogen lamp cup 4 needs to be installed more stably, the halogen lamp fixing plate 3 can be installed on the aluminum plate 2 through bolts, and a plurality of installation openings on the halogen lamp fixing plate 3 match the card slots 204 on the aluminum plate 2, then the stable installation operation of the halogen lamp cup 4 can be completed.

[0034] The guiding mechanism includes a water pipe joint 8, a connecting cavity 703, a fluid inlet 704 and a fluid outlet 706. Two water pipe joints 8 are respectively arranged on the left end cover 1 and the right end cover 7. The fluid inlets 704 are respectively opened on the left end cover 1 and the right end cover 7 inside the water pipe joint 8. The connecting cavities 703 are respectively opened on the left end cover 1 and the right end cover 7, and the connecting cavity 703 is communicated with the fluid inlet 704. Two fluid outlets 706 are respectively opened on the opposite sides of the left end cover 1 and the right end cover 7, and the fluid outlet 706 is communicated with the connecting cavity 703.

[0035] A sealing ring 14 is arranged between the cavity 201 and the fluid outlet 706 for sealing operation. Bolt holes 702 are respectively opened on the left end cover 1 and the right end cover 7, and threaded holes 202 are opened on the aluminum plate 2. The threaded holes 202 and the bolt holes 702 can match each other for fixing screws 9 to fix.

[0036] Embodiment 2:

[0037] Combine with Figures 1-9 , on the basis of Embodiment 1, the further improvement of this embodiment lies in: two left and right mounting plates 10 are fixed inside the aluminum plate 2, and a plurality of intermediate mounting plates 13 are equidistantly arranged inside the aluminum plate 2 between the two left and right mounting plates 10. A protective rubber strip 11 is arranged between the left and right mounting plates 10 and the intermediate mounting plates 13, and a filter glass 12 is installed between the protective rubber strips 11.

[0038] It should be noted that the filter glass 12 is a structural component that can filter out light in the required wavelength band.

[0039] Fin strips 203 are symmetrically fixed inside the aluminum plate 2.

[0040] The implementation principle of a halogen lamp heat dissipation structure in this application is as follows: Connect the water pipe 16, data cable 17, execution unit 18, cooling liquid circulation device 19, processing unit 20, display screen 21, and other necessary modules 22 of the color sorter together. When the color sorter is started, the halogen lamp assembly 15, execution unit 18, cooling liquid circulation device 19, processing unit 20, and other color sorter modules 22 start working synchronously. At this time, the circulating coolant starts to circulate before the halogen lamp assembly 15, execution unit 18, and cooling liquid circulation device 19; the temperature sensor 6 monitors the temperature changes at several positions on the aluminum profile 2 in real time and transmits the signals to the processing unit 20. If the temperature changes at each position exceed the allowed range, the processing unit 20 issues an instruction to the execution unit 18. After receiving the signal, the execution unit 18 gradually and slowly increases the liquid flow rate and decreases the liquid temperature according to the pre-set values until the temperature data transmitted by the temperature sensor 6 is within the allowed range. Then, the processing unit 20 issues an instruction to the execution unit 18 to maintain the existing flow rate and temperature; otherwise, reverse regulation is performed until the temperature is stable.

[0041] It should be noted that the execution unit 18 is a device for controlling the liquid temperature and flow rate of the coolant circulation device.

[0042] The cooling liquid circulation device 19 is a power source for driving the cooling liquid to move in the flow pipeline, and it consists of parts such as a pump body, a cooling fan, heat sinks, and a control system.

[0043] 20 is the processing unit for all signal inputs, information processing, and instruction issuance in the entire color sorter system.

[0044] The display screen 21 is a human-machine operation interface, which is used to display information such as the coolant flow rate and temperature, and serves as an input end for setting the allowed temperature change range, and also serves as an information exchange window for other operations and instructions of the color sorter.

[0045] Other components 22 of the color sorter are technical features well-known in the technical field of color sorters and will not be elaborated here.

[0046] The specific details are as follows:

[0047] First, fix the left end cover 1 and the right end cover 7 at both ends of the aluminum plate 2 respectively, that is, thread-connect through the fixing screw 9 passing through the threaded hole 202 into the bolt hole 702, so that the fluid outlets 706 on the left end cover 1 and the right end cover 7 are communicated with both ends of the cavity 201. Then install the water pipe connectors 8 on the left end cover 1 and the right end cover 7 respectively and cover the fluid inlets 704, so that the fluid inlets 704, the connecting cavity 703, the fluid outlets 706 and the cavity 201 are communicated with each other.

[0048] The circulating coolant enters the connected water pipe connector 8 from the water pipe 16 installed on the left end cover 1, then enters the fluid inlet 704, flows into the connecting cavity 703, and then flows into the two symmetrical fluid outlets 706 from the connecting cavity 703 and enters the cavity 201, and flows out from the water pipe 16 connected to the right end cover 7. By cooling the upper and lower ends of the aluminum plate 2, the halogen lamp cup 4 inside the aluminum plate 2 is cooled.

[0049] When the aluminum plate 2 continuously works and generates a relatively high temperature, due to the lower temperature in the cavity 201 and the large temperature difference between the two, water condensate beads will adhere to the fin 203. When the water condensate beads gather to a large size, they will fall on the guiding plate 205 or the fin 203 under the action of gravity, and then be discharged from the drain pipe connected to one side of the aluminum plate 2.

[0050] As a further improvement of the above embodiment: Guide plates 205 are symmetrically fixed inside the aluminum plate 2. A flowing water cavity is formed between the fins 203 and the guide plates 205. A plurality of through holes 206 are equidistantly arranged on the guide plates 205. Folding cylinders 207 are fixed on the guide plates 205, and the folding cylinders 207 cover the through holes 206. A drain pipe is arranged on one side of the flowing water groove, and the drain pipe extends out from the aluminum plate 2.

[0051] When the temperature difference between the halogen lamp cup and the cavity is large, water condensate beads will be generated on the fins. The provided guide plates can guide and collect the water condensate beads, and to the greatest extent avoid falling on the halogen lamp cup. And the plurality of through holes provided can allow the circulation of cold and hot air to ensure cooling. Moreover, the provided folding cylinders can, on the one hand, prevent the water condensate beads from passing through the folding cylinders and contacting the halogen lamp cup, and on the other hand, allow the normal convection of cold and hot air.

[0052] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
