Cooling media；One temperature sensor, it is used for the temperature for detecting the cooling media；One controller, it receives the temperature and passed
The temperature of sensor transmission simultaneously controls the power output of the heating unit accordingly.
In one embodiment, the system also includes a switch, the switch and heating unit and a power sources in series, described
Switched on-off described in controller control.
In one embodiment, the heating unit coats the cooling unit or is placed in the cooling media.
According to the second aspect of the invention, there is provided an x-ray imaging equipment, including：One X-ray tube；One exposing unit, its
Expose the X-ray tube；Just like system described above.
In one embodiment, when the X-ray tube exposes, the controller controls the heating unit to stop heating institute
State cooling media.
After x-ray imaging device power-up, X-ray tube is heated to preset temperature by the system for heating X-ray tube,
Hereafter can directly scan, without extra exposure X-ray tube, so as to extend the life-span of X-ray tube.Set in x-ray imaging
After standby long-time does not scan, the cooling media of cooling unit is begun to cool down, and the temperature of X-ray tube is maintained at default by the system
It temperature, hereafter can directly scan, without extra exposure X-ray tube, be waited so as to avoid caused by extra exposure, and
Extend the life-span of X-ray tube.
Brief description of the drawings
The preferred embodiments of the present invention will be described in detail by referring to accompanying drawing below, and make one of ordinary skill in the art more
The above and other feature and advantage of the clear present invention, in accompanying drawing：
Fig. 1 is a kind of schematic diagram for being used to heat the system of X-ray tube according to one embodiment of the invention.
In above-mentioned accompanying drawing, used reference is as follows：

The controller of 102 cooling unit 112
104 motors 114 switch
106 heating units
Embodiment
To make the object, technical solutions and advantages of the present invention clearer, by the following examples to of the invention further detailed
Describe in detail bright.
Fig. 1 is a kind of schematic diagram for being used to heat the system 100 of X-ray tube 101 according to one embodiment of the invention.System
System 100 includes a cooling unit 102, a heating unit 106, a temperature sensor 110 and a controller 112.Cooling unit 102
With cooling media, cooling media is used for and the heat exchange of X-ray tube 101.In the present embodiment, cooling media is cooling oil.It is cold
But unit 102 includes a motor 104, for accelerating the flowing of cooling media.Heating unit 106 is used to heat cooling media.
In the present embodiment, heating unit 106 is a heating wire, and it is placed in cooling oil after insulation.In other embodiments, heating is single
Member 106 can also coat cooling unit 102.Temperature sensor 110 is used for the temperature for detecting cooling media.Controller 112 receives temperature
Spend the temperature that sensor 110 is sent and control the power output of heating unit 106 accordingly.In the present embodiment, system 100 is also wrapped
A switch 114 is included, switch 114 is connected with the power supply 108 of heating unit 106 and one, the break-make of the controlling switch 114 of controller 112.
For example, when temperature sensor 110 detects that the temperature of cooling oil is less than one first preset temperature (such as 30 DEG C), controller 112
Controlling switch 114 switches on power 108, and heating unit 106 begins to warm up cooling oil.When temperature sensor 110 detects cooling oil
Temperature higher than one second preset temperature (preset temperature of the second preset temperature >=first, such as 30 DEG C) when, the control of controller 112 is opened
