The invention belongs to the technical field of electricity, and particularly relates to nano-modified transformer oil and a preparation method thereof. The transformer oil is prepared from 0.15 to 0.8% of modified aluminium nitride nano-particles and 0.2 to 1.0% of modified alpha-Al2O3 nano-particles in percentage by weight. The nano-modified transformer oil is prepared by the following steps: adding aluminium nitride nano-particles and a silane coupling agent into an organic solvent to carry out sonic oscillation for 1 to 2h, then adding methyl methacrylate, carrying out water bath reaction at 60 to 80 DEG C for 10 to 12h, ball-milling, carrying out rotary evaporation for removing the organic solvent, drying, obtaining powder, then carrying out Soxhlet extraction with methylbenzene, and then carrying out devolatilization, thus obtaining the modified aluminium nitride nano-particles; modifying alpha-Al2O3 nano-particles with a sodium laurate solution to obtain the modified alpha-Al2O3 nano-particles; adding the modified nano-particles into base oil, then adding a molecular sieve for adsorption, and filtering. The nano-modified transformer oil prepared by the method has excellent heat-conducting property and electrical performance.

The invention discloses a transverse vacuum heat collecting pipe solar steam generating method. A transverse vacuum heat collecting pipe solar steam generating device manufactured according to the method consists of a connecting device and a heat collecting pipe. The device is characterized in that: the heat collecting pipe is placed transversely; and the device comprises a multi-level water stop device communicated with the connecting device or the heat collecting pipe, and the water level state in the heat collecting pipe is changed together with the change of the state of the multi-level water stop device. The device has the advantages that: the heat collecting pipe is arranged horizontally, so that each part distributed along the axis has good working condition consistency; the heat transfer distance of an inner glass tube from a heating area to a water storage part is short; glass rather than a capillary material can be used for heat transfer, so that the problem of scaling of a capillary liquid absorbing material is avoided; the water stop device enables the water level state in each heat collecting pipe to be consistent when the connecting device is installed with an inclination angle along the axis; and by adopting a microcomputer control system, various complex functions can be realized, the performance of a two-phase stream heat exchange and collection device is greatly improved, and the device can be in seamless transition with a production process. An embodiment is provided by combining the drawing.

The invention discloses an internal glass finned-plate tube solar energy steam producing device which comprises an internal glass finned-plate tube and a union box, wherein the union box comprises a water incoming / outgoing connector and a steam outlet pipeline; the device is characterized in that the horizontal error of both ends of the internal glass finned-plate tube is less than plus or minus 15mm; the device comprises a multi-water-level water retaining device, and the state of water levels in heat collecting tubes changes with the change of the state of the multi-water-level water retaining device. The internal glass finned-plate tube solar energy steam producing device has the beneficial effects: the heat collecting pipes are horizontally arranged and all parts which are distributed along an axial lead have good working condition consistency. The small exterior of the diameter of the internal glass finned-plate tube is covered by a metal plate; an internal glass tube and a metal layer can be used for directly transmitting heat to a water storage area from a heated area without using a capillary material to pump water so as to avoid the scale formation problem of the capillary material. A multi-water-level water retaining device is adopted for conveniently withdrawing water at a low water level and leading the heat collecting tubes to simultaneously feed water at a high water level. A microcomputer control system can realize various complex functions, substantially increases the performance of the steam producing device and is seamless jointed with a productive technology. An embodiment is provided in conjunction with figures.
