Abstract

The utility model discloses an electric heating heat-transfer device with high efficiency and energy saving. The electric heating heat-transfer device is characterized in that a heater is used for directly heating a heated medium (mineral insulating oil), and heat is transferred quickly via a super-conducting heat pipe for the utilization of various heat exchangers. The utility model having the advantages of high heating efficiency, electricity saving, quick heat transfer, simple structure, low cost, little maintenance and no environment pollution can be widely used for civil heating, various heat exchangers, heat transmitters, electric water heaters and other civil and industrial fields. Particularly when the electric heating heat-transfer device is used for civil heating, ten standard 60 type radiators can be driven by 800-watt electrical power in order to satisfy the requirement of heating in winter for an ordinary family, hot water can be supplied, and traditional heating mode can be replaced.

Description

A kind of electrical heating heat transfer unit (HTU)

The utility model belongs to the electrical heating heat transfer unit (HTU), particularly a kind of energy-efficient electrical heating heat transfer unit (HTU).

At present, electric heater unit is of a great variety, but majority is to utilize electric energy heating heating to heat various heated mediums afterwards through the insulation sealing, and this class electric heater unit is owing to be not directly to heat heated medium, but heat, so all exist shortcomings such as efficient is low, power consumption is big by the heat conduction form.

The purpose of this utility model is to propose a kind ofly electric heater directly to be heated heated medium and by superconduction heat transfer element heat transfer, heat energy is passed to other various heat exchangers etc. dispel the heat energy-efficient with Danone, as to obtain good heat transfer effect technical scheme.

This programme is achieved in that by power supply through raising frequency to 400～600Hz or higher, be connected in series mutually with the heating wire of heater then, heating wire is coiled type, segmentation is on a flange-cooled iron core, this heater places super heat-conductive pipe, and place together in the fuel tank of sealing, inject mineral insulation oil in the fuel tank as heated medium.High frequency electric makes the electrothermal wire heating on the one hand, simultaneously because the heating wire of coiled type and interior iron core thereof produce eddy current effect, improved the efficiency of heating surface, fin has strengthened the contact area with heated medium, makes this programme compare the thermal efficiency with traditional structure and improves greatly; Heated medium reaches other with heat fast through super heat-conductive pipe and dispels the heat as air, water, wet goods heated body or various heat exchangers etc.

The advantage of this programme is that heater directly heats heated medium and conducts heat through super heat-conductive pipe, so efficiency of heating surface height, saves energy, it is fast to conduct heat, and it is simple in structure, cost is low, and Maintenance free is free from environmental pollution, can be widely used in civilian and industrial circles such as civilian heating, various heat exchanger, heat transmitter, electric heater, as when being used for civilian heating, the electrical power of 800W can drive 10 of standard 60 radiators, makes 37m in 12 hours ²Living space under outdoor-17 ℃ of environment, be warming up to 25 ℃ of room temperatures, be expected to replace traditional heating mode.

Fig. 1 is the structural representation of this programme;

Fig. 2 is the structural representation of heater;

Fig. 3 is the electrical principle block diagram;

Fig. 4 is the structural configuration schematic diagram of this programme when being used for civilian heating.

Further specify the embodiment of this programme below with the civilian heating mode of Fig. 4: housing 1 is made by sheet metal, assemblies such as high frequency electric source case 2, fuel tank 5, heater 6, super heat-conductive pipe 7 are equipped with in its inside, in the high frequency electric source case 2 high frequency electric source is housed, its electrical principle block diagram such as Fig. 3 show, it is the variable-frequency power sources of a routine, frequency conversion output 400～600Hz or higher high frequency electric are for heater 6 usefulness.Iron core 13 is a flange-cooled hollow-core construction in the heater 6, fin is segmentation and arranges, in the middle of two fin, be equipped with insulating support 14, be wound with the coil of forming by heating wire 15 on it, make heating wire turn-to-turn and interlayer mutual insulating, draw by porcelain insulating sleeve pipe 16 at heating wire 15 head and the tail two ends, is connected in series with the high frequency electric source output by A, B two ends.Fuel tank 5 is a closed tube shape structure, and wherein super heat-conductive pipe 7 is fixed on the bottom of fuel tank 5 by support 12, also is connected with super heat-conductive pipe joint 11 on the super heat-conductive pipe 7 so that be connected with external device (ED) and spread out of heat; Heater 6 places in the super heat-conductive pipe 7 and is fixed in fuel tank 5 bottoms; Inject mineral insulation oil 9 as heated medium by oil filler point 3 in the fuel tank 5; Spirality water pipe 8 can be installed on the outside wall surface of super heat-conductive pipe 7, add cold water, enter water pipe 8 and be heated back by hot water outlet 10 outflow confession hot water by water inlet 4.

Structural configuration schematic diagram when Fig. 4 is used for civilian heating for this programme, connect super heat-conductive pipe 17 by super heat-conductive pipe joint 11, it is directly inserted radiator 19 as in the normal domestic use radiator by plug 18, to heating by heated mediums such as oil in the hand-hole 20 adding fin 19 or water, for civilian heating, radiator 19 can be organized use more, and use silk 21 is coupled together each group this moment, and corresponding super heat-conductive pipe 17 lengthenings are to strengthen area of heat-supply service.
