Abstract

A circuit heating state display device comprises a housing, and is characterized in that the work circuit of the device is composed of a stabilized power supply, a temperature control switch, a display light and a heat radiation fan, wherein the stabilized power supply, the temperature control switch, the display light and the heat radiation fan serve as the core of the circuit. The circuit heating state display device can be used for the automatic detection and display of heating degree during the whole working process of the circuit, helps to prevent circuit elements from damage, and enables the service life of the circuit to be prolonged.

Description

Circuit febrile state display device
Technical field
The utility model relates to a kind of detection display device, particularly a kind of circuit febrile state display device.
Background technology
In the existing electronic equipment, generally all only adopt finned, fan heat radiation, do not have circuit febrile state display device, cause easily because of the overheated circuit component that damages for high-power circuit, element.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned weak point, and provide a kind of the degree of heat in the circuit working overall process to be detected demonstration automatically, prolonging the circuit component circuit febrile state display device in serviceable life.
The purpose of the utility model is achieved in that circuit febrile state display device comprises shell; The operating circuit that it is characterized in that it is that core is formed with stabilized voltage supply IC, temperature detect switch (TDS) K1, K2, display lamp LED1, LED2, radiator fan M; Wherein IC input end and connect anodal, temperature control normal open switch K1 one end of capacitor C1 is the positive source input end, and the IC output terminal connects also that capacitor C2 is anodal, temperature control normally closed switch K2 one end; The K2 other end and connecting resistance R1 one end, diode D1 positive pole; It is anodal that the R1 other end connects LED1, and the D1 negative pole also connects diode D2 negative pole, anodal, M one end of capacitor C3, and the K1 other end also connects D2 positive pole, resistance R 2 one ends; It is anodal that the R2 other end connects LED2; C1, C2, C3 negative pole, IC common port, LED1, LED2 negative pole, the M other end and ground connection are the power cathode input end, and each element is installed in the enclosure, on the panel.
The utility model, is installed in temperature detect switch (TDS) K1, K2 on tested high-power circuit, the element radiating sheet during use owing to adopt above design, and when circuit temperature was lower than the setting value operate as normal, K1 broke off, K2 is closed, the M low-speed running, and LED1 lights; When circuit temperature was elevated to setting value, K1 was closed, the M full-speed operation, and LED1, LED2 are simultaneously luminous; When circuit temperature was higher than setting value, K2 broke off, K1 is closed, and LED1 extinguishes, and LED2 is luminous, and warning circuit is in the condition of high temperature, should be out of service.The degree of heat in the circuit working overall process is detected demonstration automatically, avoid circuit component to damage, increase the service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model operating circuit circuit diagram.
Embodiment
Combine the accompanying drawing illustrated embodiment that the utility model is made detailed description at present.
As shown in Figure 2, operating circuit is that core is formed with stabilized voltage supply IC, temperature detect switch (TDS) K1, K2, display lamp LED1, LED2, radiator fan M, wherein IC input end and connect that capacitor C1 is anodal, temperature control normal open switch K1 one end; Be the positive source input end; The IC output terminal also connects capacitor C2 positive pole, temperature control normally closed switch K2 one end, the K2 other end and connecting resistance R1 one end, diode D1 positive pole, and it is anodal that the R1 other end connects LED1; The D1 negative pole also connects diode D2 negative pole, anodal, M one end of capacitor C3; The K1 other end also connects D2 positive pole, resistance R 2 one ends, and it is anodal that the R2 other end connects LED2, C1, C2, C3 negative pole, IC common port, LED1, LED2 negative pole, the M other end and ground connection; Be the power cathode input end, each element is installed in the enclosure, on the panel.
