Abstract
The utility model discloses a round temperature-sensitive bimetallic strip comprising a round bimetallic strip body, and the central cross section of the bimetallic strip body is arc-shaped. By employing coating provided by the utility model, the round bimetallic strip can be protected, and during the thermal conduction and heat radiation process, the thermal conduction process can be accelerated, the thermal conduction time is reduced, and the sensitivity of temperature control is improved. The round temperature-sensitive bimetallic strip can response to an appointed temperature and adopt corresponding motions, and therefore the operation of a device accords with requirements, safe use of the device is guaranteed, and products are high in quality and good in performance.
Description
Technical field
The utility model relates to temperature control field, particularly a kind of circular thermosensitive bimetal.
Background technology
Temperature-sensitive element, is that physical property by some object varies with temperature and the sensitive material that changes is made.Such as: fusible alloy or temperature-sensitive insulating material, bimetallic disk, thermocouple, thermistor, semi-conducting material etc.The pop one's head in operating temperature of sensitivity at different levels probe of constant temperature, different constant temperature is not more than respectively 1 grade 62 ℃, 2 grades 70 ℃, 3 grades 78 ℃.
Temperature-sensitive element has with its resistance value of linear change of the temperature also feature of linear change, and therefore, temperature-sensitive element can utilize its temperature variant linear characteristic detect, show and control for various device or ambient temperature.On market, some terminal equipment and electrical equipment require heating rate fast, therefore require the temperature-sensitive sensitivity of thermostat high.And in existing temperature control technology field, temperature detect switch (TDS) is due to the reason of bimetallic disk material and shape, cause control system can not when the temperature of appointment, produce corresponding actions in time, thereby the continuous service that causes control system, the needed temperature of uncontrollable end product, can cause in the situation of high temperature simultaneously and burn product and even cause fire.Due to the restriction of the aspects such as shape and material and production technology, make temperature detection scope and the accuracy of detection of temperature-sensitive element limited.
Utility model content
The defect existing in order to overcome above-mentioned prior art, the utility model provides a kind of circular thermosensitive bimetal, can respond fast the critical point of variations in temperature.
To achieve these goals, the technical solution of the utility model is as follows:
A thermosensitive bimetal, comprises sheet metal body, and described body is circular, and described body is arc along the cross section at center.
As preferably, sheet metal radius described in the utility model is 12.7～12.9mm.
As preferably, the camber of arc described in the utility model is 0.3～0.65mm.
As preferably, sheet thicknesses described in the utility model is 0.1～0.2mm.
As preferably, sheet metal described in the utility model surface arranges coating.
As preferably, coating layer thickness described in the utility model is 0.001～0.005mm.
The beneficial effects of the utility model are; coating not only plays a protective role to disk; in heat conduction and thermal-radiating process; can also accelerated heat process and time of conduction, improved temperature controlled sensitivity, to the temperature of appointment, can respond in time to take corresponding action; the operation of equipment is met the requirements; support equipment uses safety, and product quality is high, and usefulness is good.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model;
Fig. 2 is that the utility model is along the sectional view at center.
In figure, 1, body, 2, coating.
Embodiment:
In order to make creation characteristic of the present utility model, technological means and to reach object, be easy to understand understanding, below in conjunction with accompanying drawing, further set forth the utility model.
Referring to Fig. 1～2, a kind of circular thermosensitive bimetal, comprises sheet metal body 1, and described body 1 is circular, and described body 1 is arc along the cross section at center.Described sheet metal radius is 12.7～12.9mm.The camber of described arc is 0.3～0.65mm.Described sheet thicknesses is 0.1～0.2mm.Described sheet metal surface arranges coating 2.Described coating 2 thickness are 0.001～0.005mm.By the processing of spraying paint of bimetal leaf surface, obtain spraying protective layer.Wherein, coating is generally black, temperature detect switch (TDS) is when experiencing heat like this, in heat conduction and thermal-radiating conductive process, process and time this kind of technique of having played accelerated heat conduction have improved the speed of experiencing heater temperature greatly, have also promoted thermostat to temperature controlled sensitivity simultaneously.Because body part is circular, circular body is the arc of projection gradually from outer rim near center, make sheet metal when being heated, be more prone to produce corresponding mechanical action when reaching zero point, projection is uniformly distributed, while there is mechanical action, force distribution is even, thereby can evenly pass to metal disk body, increased the accuracy to the susceptibility of temperature and mechanical action.Bimetallic disk, for temperature detect switch (TDS), as the temperature sensitive member of temperature detect switch (TDS), can be experienced the temperature of heater fast, promotes thermostat to temperature controlled sensitivity.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
