Description

TECHNICAL FIELD

[0002] Heat radiation refers to the phenomenon that electromagnetic waves are radiated by an object due to temperature rise, and when heat radiation irradiates the surface of a to-be-heated object, part of the radiation is absorbed by the to-be-heated object, so that the temperature of the to-be-heated object is raised to achieve the purpose of heating (commonly used for crystal purification, metal melting or plastic forming, etc.); an incandescent lamp as a commonly used heat radiation source generates heat radiation through the electric heating effect, that is, when electric current passes through the filament, the filament is constantly heated due to the existence of resistance, and the temperature rise of the filament makes the atoms and molecules inside the filament vibrate at a higher speed, and these vibrations change the charge distribution between the atoms and molecules, thereby generating the electromagnetic waves.

[0003] In order to make more heat radiation concentrate on the to-be-heated object, a reflection cover is usually sleeved on the heat radiation source, and the reflection cover is provided with a reflection cavity for concentrating and reflecting heat radiation in a specified direction; when the to-be-heated object is placed at the opening of the reflection cavity, part of the heat radiation of the heat radiation source directly irradiates the to-be-heated object, and most of the heat radiation irradiates the to-be-heated object through reflection after irradiating the reflection cavity, so that more heat radiation is concentrated on the to-be-heated object, the heating efficiency is improved, and the utilization rate of heat radiation is improved.

[0004] However, in actual application, the heat emitted by the heat radiation source is quite high and far higher than the melting point of the reflection cover, and at the same time, the heat dissipation effect of the reflection cover in the prior art is not ideal, so that the reflection cover is easily melted or damaged due to long radiation time or too much heat absorbed by the reflection cover, which leads to the problems of high difficulty and high cost of heat radiation heating work.

Detailed Implementation

[0032] 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.

[0033] like Figures 1-4 As shown, this utility model provides a split-type infrared heating reflective bulb, including a housing 1 and a heating element 2. The housing 1 has a through hole 11 that penetrates the housing 1 along the central axis L. The housing 1 includes a heat dissipation part 12 and a heat-gathering part 13. The heat dissipation part 12 has a heat dissipation cavity 121 that communicates with the through hole 11. The heat dissipation part 12 also has a liquid inlet hole 122 and a liquid outlet hole 123 that communicate with the heat dissipation cavity 121 respectively. The end of the heat-gathering part 13 has an inwardly recessed arc-shaped heat-gathering cavity 131. The heating end 21 of the heating element 2 passes through the heat dissipation part 12 and the heat-gathering part 13 along the through hole 11 and extends into the heat-gathering cavity 131.

[0034] In use, the object to be heated is placed at the opening of the heat-gathering cavity 131. The heating element 2 emits thermal radiation, some of which directly irradiates the object to be heated, while most of the thermal radiation irradiates the heat-gathering cavity 131 and is then reflected back to the object to be heated. This concentrates more thermal radiation onto the object to be heated, thereby improving the heating efficiency of the bulb and the utilization rate of thermal radiation. At the same time, since most of the thermal radiation irradiates the inner wall of the heat-gathering cavity 131, the shell 1 will absorb some heat, causing the shell 1 to heat up. In order to achieve the best cooling effect, liquid cooling technology is adopted in this embodiment. That is, when the bulb is working, a large amount of coolant enters through the liquid inlet 122 and fills the heat dissipation cavity 121. After the coolant fully contacts the inner wall of the shell 1 and the outer peripheral wall of the heating element 2 and absorbs heat, it is discharged from the liquid outlet 123. This cycle is repeated to achieve a rapid and efficient cooling effect for the shell 1, thereby improving the service life of the bulb, effectively reducing the difficulty and cost of thermal radiation heating, and providing a good and stable working environment for the bulb to heat up.

[0035] It should be noted that in the present embodiment, the inner wall of the heat collecting cavity 131 can be a hemispherical surface or a hemi-ellipsoidal surface, so that more thermal radiation energy can be accurately reflected to the object to be heated through the inner wall surface of the heat collecting cavity 131; at the same time, in the present embodiment, the bulb also uses infrared heat radiation.

[0044] Preferably, the locking part 221 is provided with "C" shaped avoiding holes 2211 corresponding to the positions of the inlet hole 122 and the outlet hole 123 respectively.
