3results about How to "Lower working environment" patented technology

The utility model belongs to the technical field of medical equipment, and particularly relates to a water purifier water storage tank disinfecting and killing device which comprises a water storage tank cover body and a disinfecting and killing lamp source, the disinfecting and killing lamp source is arranged in an installation through groove formed in the water storage tank cover body in the axial direction, and a heat dissipation assembly is arranged on the disinfecting and killing lamp source. At least one part of the heat dissipation assembly extends out of the mounting through groove towards one side of the cover face of the water storage tank cover body and is covered with a protective cover, and a plurality of through holes are formed in the protective cover and correspond to the heat dissipation assembly for air flow circulation. The heat dissipation assembly is arranged on the disinfection lamp source for heat exchange and heat dissipation, the working environment of the disinfection lamp source is greatly reduced, the service life of the disinfection lamp source is effectively prolonged, the working stability of the disinfection lamp source is effectively improved, through holes are formed in the protective cover to form airflow circulation, and heat flow is directionally and efficiently discharged out of the device.

The utility model belongs to instrument installation structure technical field especially relates to a in situ laser gas analysis instrument cooling installation structure. Including in situ laser gas analysis instrument head, cooling chamber, gas source input pipe, vortex pipe, gas output pipe, cooling chamber is casing structure, and the left and right sides are provided with power cord connecting hole and signal line connecting hole respectively, and the back is provided with meter head hole, and the front side is provided with observation window, and in situ laser gas analysis instrument head sets up in the middle of cooling chamber, and gas source input pipe is connected to vortex pipe high pressure gas entrance, and vortex pipe's cold gas output pipe is connected to air inlet hole, and gas output pipe is connected to air outlet hole. The application can effectively isolate and protect the meter head structure that is easily damaged under high temperature environment in high temperature environment, and then can continue to use it in high temperature environment, guarantee each electrical element in lower working environment, guarantee its data precision, improve its performance.

The application discloses an LPCVD heating furnace body, which comprises a heating furnace, a quartz tube arranged in the heating furnace, a furnace tail sealing ring arranged outside the end of the quartz tube, and a flange structure arranged between the quartz tube and a furnace cover. An airflow guide device is arranged axially inside the end of the quartz tube, the axial length of the airflow guide device covers at least the axial position of the sealing ring, the airflow guide device has an airflow guide channel inside, and the inner end outer wall of the airflow guide device is connected and sealed with the inner wall of the quartz tube at the corresponding position. The hot airflow can pass through the airflow guide channel without directly contacting the position of the sealing ring, so that the working environment of the sealing ring is reduced by about 80-120 DEG C compared with the previous one, and the service life of the sealing ring can be effectively prolonged. In addition, the flange structure adopts an independent cooling water pipe design, the cooling water pipe generating scale can be conveniently disassembled and replaced, and the cooling effect and service life of the flange are avoided from being affected.
