Abstract

This invention provides a heat body and heater. Wherein, the heat body is long-size thin plate with even cross section and long direction as vertical side; arranging opposite switches on vertical sides with space; the heater is formed by packaging the heat body into a glass tube, a metal member connects the heat body ends and wires. The invention changes the heat body impedance value without any change to original physical strength and the zigzagging loop, has high efficiency and utility, enlarges contact area, and ensures the service time.

Description

A kind of heater and the heating element that uses this heater to make

Technical field

The present invention relates to a kind of electro-heat equipment, particularly a kind of heater and the heating element that uses this heater to make.

Background technology

The technology of utilizing the conductor energising to emit light and heat has been well-known, its main means are that conductor is sealed in the glass tube (quartz ampoule) that inert gas is housed, the conductor two ends are connected with external power source by the lead that passes glass tube, make the conductor energising produce heat energy.Increase the generation of heat energy, will increase the resistance value of conductor, at present generally adopt that to reduce cross-sectional area of conductor long-pending or add the electrical impedance that mode such as adhesive is adjusted conductor in conductor material.It is long-pending to reduce cross-sectional area of conductor, and as osram lamp, it adopts helical heater, but helical heater is too thin, very easily fractures, and because the heterogeneity of screw pitch is easy to produce the heating inequality, causes filament fusing.Add adhesive and make properties of materials that change take place in conductor material, conductor has become fragile, and useful life is also short.For addressing these problems, adopt the round bar shape heater of the entire body sectional area homogeneous of hard, solve the uneven problem of heating, but will increase caloric value, generally realize by many heaters of connection arranged side by side.Adopt the heating element of this structure, also there are following some shortcomings, each heater only both ends support has support, influenced by external force and be easy to broken string, many heaters are put and are installed in side by side in the same glass tube, and being electrically connected each other is very loaded down with trivial details and difficult, and heater is the pole shape, its with lead between be connected also and must carry out complex structure by the connecting portion of coiled type.

Summary of the invention

The objective of the invention is provides a kind of and does not need to sneak into adhesive for solving above-mentioned the deficiencies in the prior art, keeps material constant, but can increase the heater of the special shape of electrical impedance, raising heat generation rate, reach the heating element made from this heater.

The technical scheme that the present invention provides for achieving the above object is, a kind of heater, and it is, and the long uniformly chi of sectional area is lamellar, and its length direction is vertical limit, and its Width is a widthwise edge, on two vertical limits, is provided with opening separately and in opposite directions.

For guaranteeing heating evenly, above-mentioned heater is between adjacent opening, and the spacing of its adjacent edge is identical with the spacing dimension of the vacancy of opening part.

A kind of heating element, it is packaged in the glass tube by above-mentioned heater and constitutes, and is connected by clipping metalwork between the two ends of heater and the lead.

Described clipping metalwork is made of grip block and " U " clevis that is used for grip block is compressed, and the openend of " U " clevis is turned up to the outside, forms the outstanding wing.Grip block is outwards turned up by an end of heater, forms insulation board.

Be used to encapsulate the interior caliber of glass tube of heater and the width of heater, the widthwise edge of the lamellar heater of promptly long chi is consistent.

The invention has the beneficial effects as follows: by the staggered open design of heater,, changed resistance value, had the heating efficiency height, the characteristics that stock utilization is high not changing material, keeping forming the long power circuit of shape that crawls under the situation of the original physical strength of heater.Heater is packaged in made heating element in the glass tube thus, its two ends are connected with lead by clipping connection metalwork, have increased contact point, simultaneously owing to the support of glass tube inwall to heater, making it can be not influenced because of vibrations, has guaranteed the useful life of heating element.

The present invention is further elaborated by embodiment below in conjunction with accompanying drawing, but embodiment does not limit protection scope of the present invention.

Embodiment

Embodiment 1:

As shown in Figure 1, heater 1 of the present invention, it is lamellar that it is the long uniformly chi of sectional area, and its length direction is vertical limit 2, and its Width is a widthwise edge 3, and its two ends are provided with wire interconnecting piece 11, on two vertical limits 2, are provided with opening 4 in opposite directions, separately.Between the adjacent opening 4, the spacing of its adjacent edge is identical with the spacing dimension of the vacancy part of opening 4.

Embodiment 2:

As Fig. 2, shown in Figure 3, be connected by clipping metalwork 6 by between embodiment 1 described heater 1 and the lead, connecting clipping metalwork 6 is made of two grip blocks 8 and " U " clevis 9 that is used for grip block 8 is compressed, the openend of " U " clevis 9 is turned up to the outside, form the outstanding wing 10, be convenient to fix two " U " clevis relative engagement, grip block 8 is fixing with heater 1.Grip block 8 is outwards turned up by an end of heater 1, forms insulation board 7.The zone isolation of heating position zone and wire interconnecting piece is come, prevent scattering and disappearing of heat.In actual use, insulation board 7 can be made different geometries with the outstanding wing 10.

Embodiment 3:

As shown in Figure 4, the heater 1 that is connected with lead by clipping metalwork 6 described in the embodiment 2 is packaged in the glass tube 5, forms heating element.Lead passes from the top of glass tube 5, encloses inert gas in the glass tube 5.Body heater 1 just can be switched on to the heater 1 in the glass tube 5 by deriving the lead outside glass tube 5.As shown in Figure 5, be used to encapsulate the interior caliber of glass tube 5 of heater 1 and the width of heater 1, promptly widthwise edge 3 is consistent.Like this, the long limit of heater 1 firmly is supported on the inwall of glass tube 5, can reduce the vibration effect of external force, has guaranteed useful life.

Embodiment 4:

Body heater 1 of the present invention adopts the size of thick 0.4mm, wide 7.8mm, long 350mm, cold impedance is worth the body heater (imperforation processing) of 2.5 Ω, make that the cold impedance value is 23 Ω (electric current 7.5A when voltage 100V) after the 2.5mm spaced apertures, make that the cold impedance value is 46 Ω (electric current 3.3A when voltage 100V) after the 1.5mm spaced apertures, heater is according to the opening difference that forms, in the scope of realistic scale, resistance value can improve 5 to 30 times.In the present invention, opening interval to each other can be set according to body heater 1 desired electric opposing value, and thickness or width are changed accordingly.
