Description

Nonmetal far infrared dynamic heat device

The utility model relates to a kind of fluid heater that heat-generating device is arranged, and specifically a kind of water and heat medium are the heaters that is separated from each other.

Existing heater is varied, as thermocouple, " immersion heater " or the like.This class heater belongs to the work of outer containing shape, but heater directly contacts with heated object.Thereby when work, heated object has corrosion phenomenon to it, thereby has influenced service life.If install body additional by the conduction oil indirect, though the heater life-span can prolong, cost increases, and the heat energy utilization rate descends.Thereby this class heater life-span is shorter, and antiacid alkali ability is poor, may pollute heated object, and can not dry combustion method, and belong to static heating, to the dynamic heat of specific (special) requirements is arranged, then can not use.

The purpose of this utility model just provides a kind of nonmetal far infrared dynamic heat device that heated object, corrosion-resistant, high temperature resistant, long service life and dry combustion method do not influence the life-span that do not pollute.

The utility model is achieved in that this heater is to be sealed with airtight interior cover in the shell of band fluid inlet and outlet, be sealed with the inner core frame in the interior cover, be wound with electric heating element on the inner core frame, an end of electric heating element passes the inner core frame, is connected on the binding post of calandria end with other end branch.

The utility model utilizes quartz glass to make shell, interior cover and the inner core frame of heater, electric heating element is positioned among the cover of airtight vacuum state, and the heated object between interior cover and shell is isolated mutually, make electric heating element avoid oxidation and be heated the corrosion of liquid, thereby the life-span prolongation.In addition, because of quartz glass sends far-infrared spectrum after being heated, can improve the thermal efficiency effectively.Fluid inlet and outlet on the shell, available malleation or negative pressure control fluid flow are realized dynamic heat.This device is widely applicable, can and have in the dynamic heat occasion of specific (special) requirements in multiple heating occasion to use.

This heater is the outer working method that contains, and the heat energy utilization rate can reach more than 95%, and safe and reliable, long service life.Because heating source is contactless with being heated liquid, thereby without any pollution.This device is because of adopting nonmetallic quartz glass as shell, interior cover and inner core frame, thereby corrosion-resistant, high temperature resistant, and dry combustion method does not influence service life.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model.

As shown in the figure, this heater is to be sealed with airtight interior cover 2 in the shell of band fluid inlet and outlet, and interior cover 2 is a vacuum state, wherein is sealed with inner core frame 4, is wound with heating wire 5 on the inner core frame 4.One end of heating wire 5 passes from inner core frame 4, is connected on the binding post 7 of heater left part.The left end binding post 8 direct and the heater left end that is wrapped in the heating wire 5 on the inner core frame joins.

For effectively utilizing heat energy and making things convenient for processing and fabricating, the shell 1 of heater and interior cover 2 the most handy quartz glass are made cylindric.In cover 2 right-hand member wall can be adjacent to or overlap with the right-hand member wall of shell 1, the left end wall of interior cover 2 is advisable with outstanding shell 1, with link post and inner core frame thereon.The left end of inner core frame 4 is fixed on the left end wall of interior cover 2.In addition, the setting of fluid inlet and outlet on the shell also designs for making full use of heat energy and being convenient to fluid control.Be the left end bottom that fluid inlet 6 is positioned at shell 1, fluid issuing 3 is positioned at the right-hand member top of shell 1.Its advantage is that import is being descended, and liquid pours into from bottom to top, can discharge the air in the heater cavity effectively.And apply malleation or negative pressure by the convection cell import and export, can be pressed into or suck being heated liquid.Adjust the size of positive negative pressure, the control flow makes to be heated liquid and to be heated to suitable temperature.Realize the dynamic heat of liquid thus.Also can set flow,, make the heated object dynamic heat to temperature required by adjusting silicon controlled rectifier voltage.The fluid inlet branch is located at the position near the shell two ends, can make fluid fully absorb heat energy, improves the thermal efficiency.On the inner core frame of quartz glass, also can be coated with one deck far-infrared material coating, with the further raising thermal efficiency.
