High-Temperature Cooling Water Jacket for Camera

The utility model discloses a high- temperature cooling water jacket for a camera in a furnace. The high-temperature cooling water jacket comprises a water jacket body (1), a water inlet pipe (2), a water outlet pipe (3) and a compressed air joint (4). A flow-guiding cavity (13) used for separating a water cavity into an upper layer and a lower layer and provided with flow-guiding ports is arranged in the water jacket body (1). The water outlet pipe (3) and the water inlet pipe (2) are respectively arranged at the upper layer and the lower layer of the water cavity. The compressed air joint (4) is connected with an inner cavity of the water jacket body (1). The high-temperature cooling water jacket for the camera in the furnace has following beneficial effects: by the flow-guiding cavity, the water cavity is separated into two layers and therefore water enters from the lower layer and flows out from the upper layer so that water fully flow in the jacket, with the result that a cooling effect is obviously improved; compressed air is used for sweeping in place of nitrogen gas in the prior art so that problems arising from assembly of the camera in the heating furnace such as short service time and high operation cost are well solved; and the high- temperature cooling water jacket is simple in structure, convenient in installation, stable and reliable in operation and is capable of substantially reducing cooling cost.
