Mechanism and corresponding heat transfer technology.The effort of various improvement heat transfer technologies on its whole heat-transfer path, including with heat pipe, wing
Piece, using excellent chip base material of heating conduction etc., the bottleneck for breaking through chip cooling is remained difficult, particularly with high-power lamp
Body, if heat dissipation problem not can solve, lamp body temperature is high, may if the power supply line inside lamp body causes fire behavior
It will cause extreme loss.
Used by a kind of patent of invention " phase-change heat LED headlamp " of number of patent application 201610035044.7
Phase-change material is deionized water: 30 ~ 80 parts；Acetone: 10 ~ 40 parts；Ethylene glycol: 10 ~ 30 parts；Normal propyl alcohol: 10 ~ 20 parts；Chromium
Sour zinc: 1 ~ 5 part；Sodium tripolyphosphate: 2 ~ 5 parts；Trihydroxy methyl amino: 1 ~ 5 part.Although the phase-change material is using gasification
Middle heat absorption is to reduce lamp body temperature, but the phase-change material is not electrically insulated, it is impossible to be used in explosion-proof lamp body.
Summary of the invention
The purpose of the present invention is to solve the above problem, provides a kind of high efficiency and heat radiation lamp body with fire-proof function.
To solve the above-mentioned problems, The technical solution adopted by the invention is as follows:
High efficiency and heat radiation lamp body with fire-proof function includes from bottom to up light-source chamber 1, wire connection cavity 2 and power source cavity 3, under power source cavity 3
Portion is the cavity for placing power supply apparatus, is perforated above power source cavity 3 for power supply line, which is characterized in that 2 internal cavities of wire connection cavity
It is equipped with cooling dielectric in vivo, the cooling dielectric is pentafluoropropane, difluorodibromomethane, dibromotetrafluoromethane mixed liquor,
The pentafluoropropane, difluorodibromomethane, dibromotetrafluoromethane volume ratio be 1:(1 ~ 2): (1 ~ 7), pentafluoropropane, difluoro two
Bromomethane, dibromotetrafluoromethane total volume account for the half of 2 internal cavities body volume of wire connection cavity to 2/3rds, wire connection cavity 2
Top is equipped with exhaust pipe, and the exhaust outlet of exhaust pipe is equipped with rupture disk.
The operation principle of the present invention is that:
It is 15.3 DEG C of pentafluoropropane boiling point, stable at normal temperatures and pressures, it is non-ignitable.Difluorodibromomethane boiling point is 24.5 DEG C, normal
Stablize under normal temperature and pressure, it is non-ignitable.It is 47.3 DEG C of dibromotetrafluoromethane boiling point, stable at normal temperatures and pressures, it is non-ignitable.Lamp body had been heated
Cheng Zhong, pentafluoropropane, difluorodibromomethane, dibromotetrafluoromethane mixed liquor are undergone phase transition, and become gaseous state, gasification from liquid
Middle heat absorption, makes lamp body cool down.Since pentafluoropropane, difluorodibromomethane, dibromotetrafluoromethane are non-ignitable, reach the function of fire extinguishing.
The invention has the benefit that the present invention utilizes pentafluoropropane, difluorodibromomethane, the heated hair of dibromotetrafluoromethane
Phase transformation is given birth to reduce the temperature of lamp body, keeps lamp body cooling and heat dissipation effect more preferable.In addition, using pentafluoropropane, difluorodibromomethane,
The noninflammability of dibromotetrafluoromethane reaches the function of fire extinguishing, avoids power supply line aging short circuit from generating electric spark, makes lamp body more
Safety.
