Abstract

The invention relates to a high-carbon-molecule oil-electricity heat supply unit of a modular structure. The unit comprises a cabinet body, single-set heat exchangers and single-set heaters, each single-set heat exchanger comprises a first shell, a heat exchange coil pipe, a communicating pipe and leading-out pipes, the heat exchange coil pipe is arranged in the first shell, and the two ends of the heat exchange coil pipe penetrate out of the first shell through the leading-out pipes; each single-set heater comprises a second shell, heating rods, an oil outlet pipe and an oil inlet pipe, the oil outlet pipe and the oil inlet pipe are communicated with the second shell, the multiple single-set heaters are sequentially connected in series through pipelines, the oil inlet pipes and the oil outlet pipes of the head single-set heater and the tail single-set heater are communicated with the leading-out pipes at the two ends of each heat exchange coil pipe through pipelines, and inner circulation oil pumps are further arranged on the pipelines; and the multiple single-set heat exchangers are sequentially in series connection through flange bent pipes, and the communicating pipes of the head single-set heat exchanger and the tail single-set heat exchanger are respectively connected with a water inlet pipe and a water outlet pipe. The single-set heaters and the single-set heat exchangers are modularized, so that product series can be saved, waste can be reduced, and the heat exchange efficiency can be improved by connecting the multiple single-set heaters in series.

Description

technical field [0001] The invention belongs to the field of electric water heaters or electric boilers, and in particular relates to a high-carbon molecule oil-electric heating unit with a modular structure. Background technique [0002] At present, heating equipment can be divided into electric boilers, gas boilers, oil-fired boilers, and coal-fired boilers according to different fuels. In comparison, coal-fired use costs are low, so most of the heating uses coal-fired boilers, and coal-fired pollution is relatively large, so it has gradually withdrawn from the market now. Boiler explosions caused by natural gas leakage occur every year, so electric heating equipment is safer, energy-saving and environmentally friendly, without any gas emissions, and more in line with national environmental protection requirements. Therefore, it has received strong support from the state and has continued in recent years. Carry out the policy of coal-to-electricity transformation, and dis...

Problems solved by technology

[0003] Although the oil-electric water heater using heat carrier oil as the heat medium for heat exchange has solved the biggest energy efficiency and service life problems of electric water heaters at present, there are also some shortcomings in the oil-electric water heaters of the prior art. Each specification of electric water heater or electric boiler is an integral heating system, resulting in many series. At the same time, the heating method adopted is direct heating in a closed cavity without circulating the heat medium, so it directly affects the life of oil products and heating rods. At the same time, the heat exchange speed is relatively slow; for example, invention patent 200610122514X "High-carbon molecular heating oil energy-saving electric water heater", utility model patent: 2018214065575 "a high-carbon molecular heating oil electric water heater with internal and external spiral heat exchange structure", 2018218506153 "a kind of Patents such as High Carbon Molecular Heating Oil Heating Unit have a similar structure and do not use heat medium circulation. At the same time, each power specification needs to carry out the overall production of the heating system separately, so there are the above problems

In addition, although some patents use circulating oil pumps, they also have limitations. For example, patent 2017214165579 "An organic heat carrier boiler based on frequency conversion electromagnetic energy heating" uses an oil pump to circulate the heat medium inside the heater, but this patent is only used as heat carrier oil. Heating other liquids without performing heat exchange, such a structure has insufficient heat exchange area, which leads to unsatisfactory actual heating effect and cannot exert the maximum efficiency of the heater, so it still has limitations.

Or a utility model patent: 201721147305 "A High-frequency Quantum Organic Heat Transfer Boiler" has a complex structure and low safety performance. The contact between heating oil and water is easy to instantly gasify the pressure, and the effect of using gas for heat preservation is not ideal. The structure of the expander unstable

There is also an invention patent: 201510541103.3 "Electric Heating Heat Conduction Oil Furnace System" with complex structure and low integration
