Description

Technical Field

[0001] This utility model belongs to the field of thermal radiation heating technology, specifically relating to a liquid-cooled infrared heating reflective bulb. Background Technology

[0002] In applications of thermal radiation heating, light bulbs generate a large amount of heat when they are working. Traditional light bulbs have a relatively simple heat dissipation method, relying mainly on natural heat dissipation, which has low heat dissipation efficiency. Excessive temperature not only affects the lifespan of the light bulb and causes unstable heating effect, but the bulb housing may also deform due to high temperature, which in turn affects the thermal radiation reflection effect and cannot meet the stable heating requirements. This seriously restricts the performance improvement and application expansion of light bulbs in related fields. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] like Figure 1-4 As shown, this utility model provides a liquid-cooled infrared heating reflective bulb, including a cover 1 and a lamp body 2. The cover 1 is cylindrical in shape and has a reflective cavity 13 at its end. The reflective cavity 13 is coated with multiple layers of different metal films. The reflective cavity 13 has a dome-shaped arc surface. The opening of the arc surface is connected to the bottom of the cover 1, that is, the bottom of the cover 1 has an opening. The top center of the cover 1 has a window 14 that penetrates the cover 1. The window 14 is connected to the reflective cavity 13. The lamp body 2 passes through the window 14 along the central axis L of the window 14 and is placed inside the reflective cavity 13. The lamp body 2 and the cover 1 are detachably connected.

[0033] In this application, the lamp body 2 converts electrical energy into heat energy through a thermal effect. Its internal heating element generates heat and radiates electromagnetic waves with a thermal effect. When the electromagnetic waves emitted by the lamp body 2 reach the inner wall of the reflective cavity 13, their arc-shaped design reflects them towards the bottom of the cover 1. Simultaneously, the multiple layers of different metal coatings on the reflective cavity 13 increase the reflection efficiency of the electromagnetic waves, allowing the thermally-effect electromagnetic waves to be more concentrated on the outer surface of the item to be heated. The item absorbs the electromagnetic waves, causing its temperature to rise and thus heating the item. Throughout this process, the inner wall of the reflective cavity 13 absorbs some heat, thereby... The temperature of the cover 1 rises, and excessively high temperatures may damage or deform the structure of the cover 1, especially the reflective cavity 13 on the inner side of the cover 1. When the arc surface of the reflective cavity 13 is deformed, it will directly affect the reflection effect of electromagnetic waves, thereby reducing the heating effect on the object. In order to solve this technical problem, a cooling cavity 3 is provided between the outer wall of the cover 1 and the reflective cavity 13. At the same time, the cooling cavity 3 is not connected to the lamp body 2. The outer wall of the cover 1 is also provided with a water inlet 15 and a water outlet 16 connected to the cooling cavity 3. This structural design allows the coolant to form an independent water circulation system through the water inlet 15, the water outlet 16 and the cooling cavity 3.

[0034] When in use, the lamp body 2 heats up after being powered on, emitting thermal radiation electromagnetic waves with a thermal effect, which raises the temperature of the reflective cavity 13, and consequently raises the temperature of the cover 1. At this time, the water inlet 15 continuously injects coolant into the cooling cavity 3 inside the cover 1. After the coolant comes into full contact with the cover 1, it absorbs heat and is then discharged outside the cover 1 through the water outlet 16. This cycle continuously carries away the heat, thereby achieving the effect of cooling the cover 1.

[0035] Specifically, such as Figure 5As shown, in one embodiment of this utility model, the cover 1 includes component one 11 and component two 12, which are detachably connected vertically. At the connection end of the two components, component one 11 has a protrusion 111 at its bottom, and component two has a groove 112 at its top corresponding to the protrusion 111. The protrusion 111 and the groove 112 are fitted together. The water inlet 15 and the water outlet 16 are disposed inside the protrusion 111 and pass through component one 11. The cooling chamber 3 is disposed at the bottom of the groove 112 and communicates with the groove 112. This split structure design of the cover 1 into component one 11 and component two 12 makes the production of the cover 1 more convenient and efficient. Only the water inlet 15 and the water outlet 16 need to be machined on the outside of component one 11. Hole 16 is provided, and the cooling cavity 3 is machined on the top of component 2 12. If the structure adopts an integrated design, the cooling cavity 3 and water inlet / outlet holes need to be machined inside the cover 1 from bottom to top during production. This places high demands on the production machine, resulting in a significant increase in production costs and a reduction in production efficiency. The fitting structure design of the protrusion 111 and the groove 112 makes it easy to assemble and disassemble component 11 and component 2, and the connection is firm. On the other hand, it allows the water inlet hole 15 and the water outlet hole 16 inside the protrusion 111 to face the cooling cavity 3 at the bottom of the groove 112, and makes the cooling cavity 3 form a relatively sealed space, which makes it less likely for coolant to leak during the circulation of coolant.

[0036] Specifically, such as Figure 6 As shown, in one embodiment of this utility model, the cooling chamber 3 is arranged in a ring around the lamp body 2 with the lamp body 2 as the central axis. This ring structure design makes the entire circulation process of the coolant from the water inlet 15 to the cooling chamber 3 and then to the water outlet 16 smoother, reduces the occurrence of coolant backflow and blockage, speeds up the water flow, and improves the heat dissipation effect. In addition, the structure can also be rectangular. Compared with the ring, the contact area between the coolant and the cover 1 for heat exchange is increased. However, the circulation of the coolant is prone to backflow and blockage due to the rectangular design, and the water flow speed is slower. In summary, the ring structure has a fast and smooth water flow, while the rectangular structure has a large heat exchange contact area. Considering the amount of heat removed per unit time, the ring structure is more preferable.

[0037] It should be noted that the protrusion 111 and the groove 112 are both annular structures that match the cooling cavity 3, which makes the processing of the protrusion 111 and the groove 112 more convenient, which helps to improve the production efficiency of the cover 1 and reduce the manufacturing difficulty.

[0038] Furthermore, such as Figure 5-7As shown, the cooling cavity 3 can be formed by combining multiple cavities. In this embodiment, the cooling cavity 3 has two cavities, including an annular inner cavity 31 and an outer cavity 32 arranged around the lamp body 1. The inner cavity 31 is provided with a corrugated structure 311 on the peripheral wall near the lamp body 2. The groove depth of the outer cavity 32 is greater than that of the inner cavity 31. In designing the structure of the cooling cavity 3, the two cooling cavities greatly increase the contact area between the cooling cavity 3 and the coolant, and remove more heat in a single cycle. In terms of cavity depth, since the cooling cavity 3 is located between the cover 1 and the reflector 13, the space it can be set in is limited. If there is only one cavity of the cooling cavity 3, the cavity depth it can be set in is very limited and uniform. However, the two cavities can be designed with two cavities of different depths according to the arc surface of the reflector 13, that is, the depth of the outer cavity 32 is greater than the depth of the inner cavity 31, further increasing the contact area with the coolant.

[0039] Specifically, such as Figure 4 As shown, in one embodiment of this utility model, at the connection end between the water inlet 15 and the water outlet 16 and the cooling cavity 3, the inner cavity 31 and the outer cavity 32 are simultaneously connected to the water inlet 15 and the water outlet 16. This structural design enables the cooling cavity 3 to maintain the fluidity of the coolant in the multiple cavities even if it includes multiple cavities, during the water circulation process.

[0040] It should be noted that the two cavities in the cooling chamber 3 can also be designed such that the water inlet 15 is connected to the inner cavity 31 or the outer cavity 32 separately, and the water outlet 16 is connected to the other cavity separately. By communicating with the inner cavity 31 and the outer cavity 32, the water first enters one cavity through the water inlet 15 to absorb heat, then enters the other cavity to absorb heat, and finally exits through the water outlet 16. This water flow design path can also achieve a good heat absorption effect, thereby improving the heat dissipation efficiency of the cover 1.

[0041] Specifically, such as Figure 4 As shown, in one embodiment of this utility model, the water inlet 15 and the water outlet 16 are connected to the outside of the cover 1 and the cooling cavity 3, and each is provided with a thread 18 at one end near the outside of the cover 1. The thread 18 corresponds to the thread in the water inlet and outlet pipes outside the cover 1, so that the water inlet and outlet pipes can be connected more firmly in the water inlet 15 and the water outlet 16, that is, to ensure that the water flow is more stable throughout the circulation process. If the water inlet 15 and the water outlet 16 are not provided with the thread 18, and the water inlet and outlet pipes are only connected by a simple snap-fit ​​method, in actual applications, the water flow speed is relatively fast during the circulation process, which may cause the water inlet and outlet pipes to fall off, affecting the entire heat dissipation process.

[0042] Specifically, such as Figure 8 As shown, in one embodiment of this utility model, the lamp body 2 includes a lamp core 22, a lamp holder 21, and a fixing member 23. The end of the lamp core 22 passes through the fixing member 23 and extends into the lamp holder 21. The lamp holder 21 is screwed to the fixing member 23, and the fixing member 23 is screwed to the end of the component 11. This structural design allows the lamp body 1 to be fixedly connected to the component 11 of the cover body 1 through the fixing member 23.

[0043] Specifically, such as Figure 9-10 As shown, in one embodiment of this utility model, sealing grooves 112 are provided on both sides of the protrusion 111, and a sealing ring 113 is provided in the sealing groove 112. The sealing groove 112 and the sealing ring 113 are also circular, and the sealing ring 113 is made of elastic material. When connected, the sealing ring 113 is pressed in the sealing groove 112, and the protrusion 111 and the groove 121 form a snap-fit, so that the cooling cavity 3 at the bottom of the groove 121 forms a relatively closed space. In actual application, if the water flow speed is too fast during water circulation or the bulb is tilted, the water may overflow from the gap between the protrusion 111 and the groove 121. The setting position of the sealing groove 112 and the sealing ring 113 and the pressing setting eliminate this hidden danger, making the liquid-cooled bulb safer to use.

[0044] Specifically, such as Figure 10 As shown, in one embodiment of this utility model, the outer peripheral wall of the cover 1 is provided with a plurality of inwardly recessed heat dissipation grooves 17. The plurality of heat dissipation grooves are evenly spaced along the extension direction of the central axis L of the cover and are distributed in a ring around the cover 1. That is, the outer peripheral wall of the cylindrical cover 1 is covered with the heat dissipation grooves 17. When the temperature of the cover 1 rises, the outer peripheral wall can exchange heat with the air or airflow, thereby reducing the temperature of the cover 1. This structural design increases the contact area between the outer peripheral wall of the cover 1 and the air, and together with the internal cooling cavity 3, it further produces a better heat dissipation effect for the cover 1.

[0045] Specifically, such as Figure 10As shown, in one embodiment of this utility model, a plurality of screw holes 4 and screws 41 are provided on the outer wall of the cover 1 and the fixing member 23. The screw holes 4 and screws 41 on the cover 1 can all pass through the top of the component 11 to the component 22 and extend to a certain depth, so that the screw holes 4 and screws 41 fix the component 11 and the component 2 to a fixed connection. The screw holes 4 and screws 41 on the fixing member 23 pass through the fixing member 23, the component 11 and the component 22 in sequence from the top of the fixing member 23, to achieve a fixed connection between the three.

[0046] The working principle of this utility model is explained in detail below:

[0047] In use, the lamp body 2 is first connected to component 11 in the cover 1 via the fixing member 23 to ensure that all components are installed securely. After the lamp body 2 is powered on, the internal heating element generates heat and radiates electromagnetic waves outward. The electromagnetic waves are reflected by the reflector 13 to the surface of the item to be heated to achieve the heating function. At the same time, the heat raises the temperature of the reflector 13 and the cover 1. At this time, the coolant is injected into the cooling cavity 3 from the water inlet 15 on the outer wall of the cover 1 and circulates in the cooling cavity 3. Since the cooling cavity 3 surrounds the lamp body 2 and has a special groove structure, the coolant fully absorbs the heat of the cover 1 and is discharged outside the cover 1 through the water outlet 16, forming a continuous heat dissipation cycle. During this process, the sealing ring 113 prevents coolant leakage, the screw hole 4 and screw 41 ensure tight connection of components, and the heat dissipation groove 17 assists the cover 1 in heat exchange with the outside. All structures work together to effectively maintain the bulb within a suitable temperature range, ensure its stable operation, and achieve efficient lighting and heating.

[0048] The innovation of this utility model lies in its unique liquid cooling structure design. The cooling cavity between the cover and the lamp body is not connected to the lamp body. An independent coolant circulation path is formed through the water inlet and outlet holes, which avoids the safety hazards caused by contact with the lamp body. The coolant circulates in the cooling cavity, stably removes heat, maintains the temperature of the cover, prevents the reflector cavity from deforming due to overheating and affecting the electromagnetic wave reflection effect, ensures heating efficiency and stability, and extends the overall service life of the bulb.
