Description

Technical Field

[0001] This utility model relates to the field of diode heat dissipation technology, specifically a diode with a heat dissipation enhancement structure. Background Technology

[0002] When a diode is working, there is energy loss. When current passes through the PN junction of the diode, due to resistance and non-ideal characteristics, some electrical energy is converted into heat energy, causing the PN junction temperature to rise. Excessive temperature may cause "thermal runaway", resulting in a sudden increase in current and burning out the device; it can also accelerate the aging of internal materials and shorten the lifespan; it can also damage the sealing of the package, introduce impurities, and reduce reliability. Therefore, it is very necessary to cool down the diode.

[0003] For example, the patent with publication number CN218997348U discloses a cooling device for a TO-packaged laser diode array that is immersed in liquid cooling. The body and pins of the laser diode are in direct contact with the insulating coolant. The insulating coolant in the inner cavity of the tank can quickly and uniformly cool the laser diode array, thereby improving the beam quality and lifespan of the laser diode and solving the heat dissipation problem of existing TO-packaged laser diodes.

[0004] While the aforementioned patent effectively solves the heat dissipation problem of laser diodes, the body and pins of the laser diode are in direct contact with the insulating coolant. Over time, the coolant can corrode the body and pins, thereby reducing the lifespan of the laser diode.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figure 1 As shown, a diode with a heat dissipation enhancement structure includes a housing 1 and light-emitting diodes 2 linearly and equidistantly snapped onto the upper middle part of the housing 1. A coolant storage component 3 is fixedly connected to the upper middle part of the inner cavity of the housing 1. The coolant storage component 3 is configured to store coolant. A connecting component 4 is provided at one end of the coolant storage component 3. Cooling components 5 are fixedly connected to both sides of the connecting component 4. The connecting component 4 is configured to connect the coolant storage component 3 and the cooling components 5. A connecting pipe 6 is fixedly connected to one side of one end of the cooling components 5. The connecting pipe 6 is configured to realize the connection between the various cooling components 5.

[0030] like Figure 3 As shown, the upper middle part of the outer shell 1 has linearly equidistant grooves 11, and there are six sets of grooves 11. The grooves 11 are used to position the light-emitting diode 2. The lower end of the inner cavity of the groove 11 has snap-fit ​​holes 12 on both sides.

[0031] like Figure 3 As shown, the light-emitting diode 2 includes a tube body 21 and a base 22 fixedly connected to the lower end of the tube body 21. The two sides of the lower end of the base 22 are fixedly connected with snap-fit ​​blocks 23. The snap-fit ​​blocks 23 snap into the snap-fit ​​holes 12 to fix the light-emitting diode 2 in the inner cavity of the groove 11. The base 22 has a tube pin 24 passing through the middle.

[0032] like Figure 4 and Figure 5 As shown, the coolant storage assembly 3 includes a first square housing 31 and a storage tube 32 threaded into the inner cavity of the first square housing 31. The storage tube 32 is configured to store coolant. A first one-way valve 33 is provided at the middle of one end of the storage tube 32. The first one-way valve 33 is configured to prevent coolant from flowing out of the storage tube 32 when the storage tube 32 is removed. A cross cap 34 is fixedly connected to the other end of the storage tube 32. A first round tube 35 is fixedly connected to one end of the cross cap 34.

[0033] like Figure 4 and Figure 5 As shown, a first connecting hole 311 is provided at one end of the first square outer shell 31, and the first connecting hole 311 is used to connect the connecting component 4.

[0034] like Figure 4As shown, a water inlet hole 351 is provided at one end of the first circular tube 35, and a water outlet hole 352 is provided at the other end of the first circular tube 35. The coolant in the storage tube 32 flows into the inner cavity of the first circular tube 35 through the water inlet hole 351, and then flows out through the water outlet hole 352.

[0035] like Figure 4 As shown, the connecting component 4 includes a second circular tube 41 and a second one-way valve 42 fixed to one end of the inner cavity of the second circular tube 41. The second one-way valve 42 is configured to allow coolant to flow out of the second circular tube 41 when the storage tube 32 is removed. The other end of the second circular tube 41 is fixedly connected to a cross-shaped connecting pipe 43, which is configured to divert coolant.

[0036] In this application, during prolonged use of the LED 2, the coolant absorbs heat from the LED 2, causing its own temperature to rise. When the temperature reaches a certain value, the storage tube 32 is removed. When the second circular tube 41 is completely withdrawn from the inner cavity of the storage tube 32, the first one-way valve 33 closes, thereby preventing the coolant in the storage tube 32 from flowing out. Simultaneously with the complete withdrawal of the second circular tube 41 from the inner cavity of the storage tube 32, the first circular tube 35 is also withdrawn from the inner cavity of the second circular tube 41. The second one-way valve 42 closes to prevent the second circular tube 41 from flowing out. The coolant in the inner cavity flows out, replacing the coolant with a cooler one in the storage tube 32. The storage tube 32 is then screwed back into the inner cavity of the first square outer shell 31. The second round tube 41 opens the first one-way valve 33, and at the same time, the first round tube 35 opens the second one-way valve 42. The new coolant flows into the inner cavity of the first round tube 35 through the inlet hole 351 and then into the inner cavity of the second round tube 41 through the outlet hole 352. The hot coolant and the new coolant form convection due to the density difference caused by the temperature difference, thereby realizing the replacement of the coolant.

[0037] like Figure 6 As shown, the cooling assembly 5 includes a second square outer shell 51 and heat-conducting pipes 52 fixedly connected to both ends of the bottom of the inner cavity of the second square outer shell 51. The heat-conducting pipes 52 are configured to prevent the pins 24 from directly contacting the condensate while absorbing the heat from the pins 24. The inner diameter of the heat-conducting pipes 52 is the same as the outer diameter of the pins 24, so that the pins 24 can be inserted into the inner cavity of the heat-conducting pipes 52. A second connecting hole 53 is provided on one side of the second square outer shell 51, and a third connecting hole 54 is provided at one end of the second square outer shell 51. The third connecting hole 54 is configured to connect a cross connecting pipe 43. Circuit connecting blocks 55 are provided on both sides of the lower end of the second square outer shell 51. The circuit connecting blocks 55 are configured to connect an external circuit.

[0038] like Figure 2As shown, a connecting pipe 6 is provided between the cooling components 5. The connecting pipe 6 is fixedly connected to the second connecting hole 53. It is noted here that only the cooling components 5 located on both sides of the cross connecting pipe 43 have a third connecting hole 54 for connecting the cross connecting pipe 43. The other cooling components 5 are all connected to each other through the connecting pipe 6.

[0039] In this application, coolant flows into the inner cavity of the second square housing 51 through the connecting component 4, and then the coolant is convected between the various second square housings 51 through the connecting pipe 6. Then, light-emitting diodes 2 are installed, and the light-emitting diodes 2 are installed one by one according to the position of the groove 11. The snap-fit ​​block 23 is snapped into the snap-fit ​​hole 12 for fixation. The pin 24 is inserted into the inner cavity of the heat-conducting pipe 52, which isolates the pin 24 from the contact between the pin 24 and the coolant in the inner cavity of the second square housing 51, thereby solving the problem of coolant corrosion of the pin 24.

[0040] In summary: By using the LED 2, storage tube 32, second round tube 41, first round tube 35, second one-way valve 42, first square housing 31, first one-way valve 33, water inlet 351 and water outlet 352 in combination, the coolant can be replaced when the coolant temperature is too high. By using the connecting component 4, second square housing 51, connecting tube 6, groove 11, snap-fit ​​block 23, snap-fit ​​hole 12, pin 24 and heat conduction pipe 52 in combination, the contact between pin 24 and coolant is isolated, thereby solving the problem of coolant corrosion on pin.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
