Abstract
An automatic teller machine (ATM) constant temperature heating device comprises heater elements made from a PTC thermistor ceramic, white aluminium alloy radiating fins, a cylindrical aluminium box, a fan and a power supply box. Each heater element is in the shape of a rectangular sheet, each heater element is attached to one radiating fin to from a heating unit, the heating units are arranged in the cylindrical aluminium box, the fan is arranged on one end of a housing of the cylindrical aluminium box, and the power supply box is electrically connected to the fan. The automatic teller machine (ATM) constant temperature heating device is constant in heating temperature and simple in circuit structure, an overtemperature protection circuit is omitted, and hardware damages and safety problems of an automatic teller machine caused by being out of control by overtemperature are avoided.
Description
Technical field
The utility model relates to the ATM constant temperature heating device.
Background technology
In order to guarantee that ATM works under low temperature environment, automatic heating device is installed in the ATM, guarantee that ATM can work under low temperature environment.When the ATM ambient temperature is lower than set point, can automatically begin heating.When the temperature in the ATM is higher than set point, can stopped heating.The heat supply main part of existing ATM heater adopts heating wire, heat-generating pipe etc. mostly.This kind heat generating component temperature is non-constant, and is inhomogeneous, must add the overtemperature prote module, and the complexity that has increased heater has increased cost simultaneously.ATM is at longevity of service, and heater is closed down ceaselessly starting, in case the overtemperature prote module lost efficacy, temperature control causes safety problem
Summary of the invention
The utility model is intended to solve, and the heating-up temperature of the heater of ATM is non-constant, and is inhomogeneous, must have with the overtemperature module problem of temperature control.
The utility model adopts following technical scheme: the utility model comprises heater element PTC thermistor pottery, white aluminum alloy heat sink, tubular aluminium box, fan, power supply case; Described heater element profile is square sheet, and external form of cooling fin is T-shaped, and T-shaped fin is attached to respectively on two faces of heater, and heat generating component places in the square tubular aluminum alloy casing, and aluminium box gold cylindrical case one end is connected with fan.
Compared with prior art, advantage of the present utility model and effective effect are: adopt the heater of the technical program, heating-up temperature is constant, saves Overtemperature protection circuit, and circuit structure is simple, without overtemperature is out of control ATM is caused hardware damage and safety problem.
Description of drawings
Fig. 1 is the structural representation of heater element
Fig. 2 is tubular aluminium box gold shell mechanism schematic diagram
Fig. 3, Fig. 4, Fig. 5 are structural representations of the present utility model
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment
Referring to Fig. 1,2, the utility model ATM constant temperature heating device comprises heater element PTC thermistor pottery, white aluminum alloy heat sink, tubular aluminium box, fan, power supply case; Described heater element is shaped as the rectangle sheet, fits together with fin, forms heat-generating units, is installed in the tubular aluminium box, and fan places tubular aluminium box shell one end, and power supply case is electrically connected fan.
Described heater element is for just to ask that the ceramic resistor PTC of temperature coefficient is before transition temperature, the rising of electrical resistance temperature and descending, temperature be from transition temperature to the thermal runaway temperature, the rising of electrical resistance temperature and phenomenal growth, use the PTC effect, described heater element steady temperature heating.
Above-described embodiment is the better execution mode of the utility model; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection range of the present utility model.
