Fig. 1 is a schematic structural view of the whole front of the present invention.

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

Given by figure 1, an explosion-proof lamps and lanterns with heat dissipation function, including terminal box 1 and bulb 2 and terminal box 1 fixed connection, its characterized in that, terminal box 1 is equipped with the protection casing on the one side towards bulb 2, the protection casing is the inside that many bending forming's tubular metal resonator 3 cross arrangement and bulb 2 are located the protection casing, tubular metal resonator 3 is the hollow tube and a plurality of tubular metal resonator 3 insides all is equipped with coolant liquid 13.

This device is when using, at first fixes this device in the position of needs, start bulb 2, can produce a large amount of heats when putting 2 long-time uses of bulb, many tubular metals 3 absorb the heat this moment, and with heat transfer to inside coolant liquid 13, thereby realize the quick heat dissipation to bulb 2, and the protection casing is the omnidirectional and covers bulb 2, thereby improved tubular metal 3 to the 2 heat absorbing effects of bulb, further improvement radiating effect. And the protective cover can also protect the bulb 2, and the service life of the bulb 2 is prolonged.

The outer walls of the metal pipes 3 are provided with thread-shaped structures.

The area of the outer wall of the metal pipe 3 with the threaded outer wall is increased, so that the area of heat absorption is increased, and the heat dissipation efficiency is further improved.

The junction box is characterized in that a cooling liquid tank 5 is arranged inside the junction box 1, the metal pipes 3 are communicated with the cooling liquid tank 5, a water pump 6 is arranged at the bottom of the cooling liquid tank 5, and a nozzle 9 is connected to the water pump 6.

Inside coolant liquid 13 of tubular metal resonator 3 and the inside intercommunication of coolant liquid case 5, during the use, start water pump 6 for water pump 6 drives coolant liquid 13 and is vaporific through the effect of nozzle 9, dispels the heat to coolant liquid 13, thereby reduces the temperature of coolant liquid 13, so that continuously absorb the heat, further improvement the result of use of device.

The metal pipes 3 are all connected in series with a circulating pump 4.

When the device is used, the circulating pump 4 is started to circulate the cooling liquid 13 in the metal pipes 3, so that the cooling liquid 13 in the metal pipes can continuously flow, the heat absorption and heat dissipation effects are further improved, and the using effect of the device is improved.
