Abstract
The utility model belongs to an electric heating heat pipe radiator used for anti-freezing and retaining heat for the cellar of the oil field in winter. Radiating fins are uniformly distributed on the pipe wall of a radiating pipe, and the ends of the radiating pipe are closed. The lower end of the radiating pipe is connected with a heating chamber of which the outer wall is provided with an electric heating membrane. The heating chamber is filled with liquid medium. The inner past of the radiating pipe is vacuum. A conducting wire led from the electric heating membrane is connected with a temperature controller in series. The lead wire of the conducting wire is connected with an explosion-proof junction box. After the utility model is electrified, the electric heating membrane heats the liquid medium in the heating chamber, and the liquid medium is vaporized. The hidden heat of the vapor state dissipates the heat by the wall of the radiating pipe and the radiating fins. The heating and the dissipating heat are finished by the phase change and the circulation of the vapor-liquid. The utility model has the advantages of simple structure, high thermal efficiency, long life, safety, reliability and convenient use.
Description
The utility model belongs to the heater, particularly electrical heating heat-pipe radiator of oil field shaft mouth preventing freeze in winter insulation.
In order to guarantee the oilfield ordinary production, Petroleum Production department all will spend extensive fund and manpower to carry out well mouth of oil well anti-freezing and heat-insulating work in winter every year.Though also released a kind of anti-freezing and heat-insulating device on the market, as invented a kind of pipeline electric heating film heating device, can play certain anti-freezing and heat-insulating effect, its thermal efficiency is low, and power consumption is high, and application life is short, installs and uses technical condition and requires high.
The purpose of this utility model is to provide a kind of electrical heating heat-pipe radiator, heat transfer efficiency height not only, and energy conservation, long service life, and also easy to install, safe and reliable.
The utility model is achieved in that a kind of electrical heating heat-pipe radiator, comprise radiating tube, heating clamber, temperature controller and anti-explosion terminal box, uniform the radiating tube of fin on tube wall, its end sealing, the lower end of radiating tube is connecting the heating clamber that Electric radiant Heating Film is installed on outer wall, liquid medium is housed in heating clamber, vacuumizes in the radiating tube, the lead of drawing from the Electric radiant Heating Film temperature controller of connecting, the lead-out wire of lead is connecting anti-explosion terminal box.
The utility model is installed in the well mouth of oil well place, when the Electric radiant Heating Film of connecting power supply, be enclosed on the heating clamber outer wall produces heat energy, heat chamber walls, give liquid medium with thermal energy transfer, make liquid medium become steam state after making liquid medium be warmed up to certain value, and be full of the radiating tube inner chamber rapidly.The steam state medium passes to radiating pipe wall and fin with entrained latent heat, the pipeline and the oil nozzle of the heat heating well mouth of oil well that radiating tube distributes; After the latent heat of steam state medium discharges, when temperature drops to uniform temperature, the steam state medium is reduced into liquid medium and flows back to and continues heating in the heating clamber of bottom, like this by liquid steam state, the cyclic process of finishing phase transformation again and again also is the process of heating heat radiation, its heat transfer efficiency height has been saved electric energy; The temperature controller because the lead of drawing from Electric radiant Heating Film is being connected, lead-out wire is connecting anti-explosion terminal box, when heating-up temperature surpasses safe rated value, temperature controller cuts off the power supply automatically, heated pipe temperature is descended, when temperature drops to rated value, the temperature controller automatic processing circuit, continue water back, make the heating-up temperature of well mouth of oil well pipeline remain at work in the scope of safe rated value, anti-explosion terminal box and external insulation good seal performance, safe in utilization, therefore the utility model is safe and reliable, easy to use.
