Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, in particular to a radiator used for cooling electrical components. Background Art

[0002] Radiator is one of the most common devices in the prior art, and is often used for heat dissipation of structures such as circuit boards and batteries. Radiators in the prior art are generally divided into air-cooled and water-cooled. Water-cooled radiators generally use liquid refrigerant, which flows through a heat transfer plate through a pipe, and uses the continuously flowing liquid refrigerant to dissipate heat.

[0003] However, this type of water-cooled radiator in the prior art lacks an alarm mechanism at the welding and fixing positions of the pipes. Since the welding parts of the pipes are the most prone to leakage in the entire cooling system, once these welding positions slowly leak liquid or leak refrigerant, the circuit boards cooled by the device may be easily damaged or unnecessary dangers may be caused. Therefore, an improved radiator for cooling electrical components is needed to address this problem. Utility Model Content

[0006] Preferably, a collecting groove is provided on the inner side wall of the fixing ring, and the collecting groove can collect the refrigerant when leakage occurs at the welding point, thereby causing the conductivity of the first semiconductor Freon sensor and the second semiconductor Freon sensor to change.

[0007] Preferably, the first copper tube is a liquid inlet tube, and the second copper tube is a liquid outlet tube. The first copper tube is used as an inlet tube for the refrigerant, and the corresponding second copper tube is used as an outlet tube for the refrigerant.

The U-shaped aluminum tube, the connecting aluminum tube and the refrigerant flow channel of the aluminum substrate can be fixedly connected conveniently and quickly by welding, and the sealing effect can be ensured at the same time. The device is also provided with a detection mechanism at these welding positions, and this detection mechanism can be used to promptly alarm when leakage occurs at these welding points.

[0009] Preferably, a plurality of rivet nuts are evenly and fixedly disposed on the outer surface of the upper end of the aluminum substrate, and the rivet nuts are fixed to the holes originally opened on the surface of the aluminum substrate by riveting.

[0010] Preferably, the model of the first semiconductor Freon sensor and the second semiconductor Freon sensor is TGS3830; the working principle of the semiconductor Freon sensor is: TGS3830 is a metal oxide semiconductor gas sensor, mainly used to detect Freon, the sensitive element of this sensor is a tin dioxide (SnO2) semiconductor with low conductivity, but the conductivity increases with the increase of Freon gas concentration in the air; thus, it can be used to detect Freon leakage.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Once a leak occurs at the welding position of the utility model, the leaked Freon gas will cause the Freon concentration in the collecting groove to rise rapidly. After these Freon gases come into contact with the first semiconductor Freon sensor and the second semiconductor Freon sensor, the conductivity of the first semiconductor Freon sensor and the second semiconductor Freon sensor will change, which will cause the above-mentioned alarm to be energized and alarm, thereby promptly giving an alarm to notify the workers to carry out maintenance in time, thereby preventing accidents caused by refrigerant leakage.

[0013] 2. The utility model has a simple structure and does not require any other complex structure. It only needs to set a simple alarm mechanism at the welding position, which can be easily promoted and used. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The inner side wall of the fixing ring 7 is provided with a collecting groove 10, through which the refrigerant can be collected when leakage occurs at the welding point, and the refrigerant will increase the concentration of Freon in the collecting groove 10, so that the conductivity of the first semiconductor Freon sensor 8 and the second semiconductor Freon sensor 9 will change;

[0022] The first copper tube 5 is a liquid inlet tube, and the second copper tube 6 is a liquid outlet tube. The first copper tube 5 is used as an inlet tube for the refrigerant, and the corresponding second copper tube 6 is used as an outlet tube for the refrigerant.

[0025] The model of the first semiconductor Freon sensor and the second semiconductor Freon sensor is TGS3830; the working principle of the semiconductor Freon sensor is as follows: TGS3830 is a metal oxide semiconductor gas sensor, mainly used to detect Freon, the sensitive element of this sensor is a tin dioxide (SnO2) semiconductor, which has low conductivity, but the conductivity increases with the increase of Freon gas concentration in the air; thus, it can be used to detect Freon leakage;

[0026] Working principle: Before using the device, the first semiconductor Freon sensor 8, the second semiconductor Freon sensor 9, the power supply and the alarm need to be electrically connected in series, so that after the first semiconductor Freon sensor 8 and the second semiconductor Freon sensor 9 come into contact with the leaked Freon, their own conductivity changes, which can make the alarm automatically energized and alarmed;
