Abstract
An open reflection target micro-focus X-ray tube cab emit high-voltage heavy-current micro-focus X-rays with the maximum tube current reaching 3mA and the maximum tube voltage reaching 225KV, and thus the energy of X-rays is increased, and a relatively thick component under detection can be tested. A unique reflection target heat radiation apparatus ensures that the X-ray tube can work continuously with good heat radiation effect. A U-shaped water intake channel and a U-shaped water discharge channel in a target sleeve are communicated with a V-shaped water intake channel and a V-shaped water discharge channel in a water sealing block respectively. A long vertical column is disposed in the middle of the water sealing block and is inserted into a blind hole in the back of a target body and divides the target body into a water intake room and a water discharge room. The water intake room and the water discharge room are communicated with the V-shaped water inlet channel and the V-shaped water discharge channel. A 2mm gap is arranged between the long vertical column on the water sealing block and the bottom surface of the blind hole of the target body, and thus a slit is formed. The water passes through the slit, and water current in a certain flow becomes faster when the water passes through the slit, and the heat on the target body is quickly carried away, and the service life of the reflection target is prolonged.
