Abstract
The utility model discloses a PTC heating body which comprises a PTC element with an electrode, a shell, an insulation layer and a high temperature lead, wherein the PTC element is arranged in the metal shell, the insulation layer wraps outside the PTC element, and the high temperature lead is connected with the electrode and extends out of the metal shell. The PTC heating body has the advantages that the whole structure is firmly fixed and is not easy to loose, when the heating body works, the metal shell is not electrified, thus being safe and reliable, easy to install, and convenient for use.
Description
Technical field
The utility model relates to electric heater unit, and especially relating to a kind of is the heater of heater with the PTC element.
Background technology
The PTC element is a kind of semiconductor element that typically has temperature sensitivity, and when its temperature surpassed certain value, its resistance value presented increasing of step evolution with the height of temperature, and at this moment its power consumption descends, and temperature rise is slack-off, finally can be stabilized near the value.Because the responsive to temperature characteristic of PTC element is usually used in the occasion that needs heat, for example in the electric heater of air-conditioning, when overcurrent and overvoltage in circuit, occurring, also can utilize the components and parts in the step evolution protective circuit of its resistance.In actual applications, the fixed form of PTC element is different, but all exist insecure defective, for example, the PTC element is directly exposed in the environment, the surface causes the both positive and negative polarity short circuit after accumulating too much dust, burn element, perhaps the structure of ptc heater is too complicated, and volume is big, inconvenience is installed, influences its range of application.
Summary of the invention
The purpose of this utility model provides a kind of easy for installation, safe and reliable PTC calandria.
Technical solution of the present utility model is: a kind of PTC calandria, comprise the PTC element, shell, insulating barrier and the high temperature wire that have electrode, wherein said PTC element is arranged in the metal shell, insulating barrier is wrapped in outside the described PTC element, and high temperature wire connects described electrode and extends to outside the metal shell.
Insulating barrier is wrapped in outside the PTC element, integral body is arranged in the metal shell again, can prevent the accumulation of dust on the PTC element, and the insulating barrier that is provided with can make metal shell not charged, safe and reliable when work, and high temperature wire extends to outside the metal shell, the convenient installation, whole elements are as an integral installation, and are easy to operate, safe in utilization.
Be arranged with sleeve pipe outside described electrode and the described high temperature wire junction.Provide further protection to the junction.
Described PTC element is rectangle or circle.Be applicable to various application scenarios.
The utility model has the advantages that: the overall structure fixation, be difficult for getting loose, metal shell is not charged, safe and reliable constantly in work, installs easily, and is easy to use.
