The invention discloses a simultaneous co-injection forming device, belonging to the field of plastic product forming technology. The device is characterized in that a middle sliding block and a cylinder of the device are connected with each other; the middle sliding block can reciprocate with the cylinder; a runner on the middle sliding block can be communicated with an internal layer resin runner on a positioning plate and a central column; the runner on the middle sliding block can be communicated with an external layer resin runner on the positioning plate and a clapboard; the resin which enters the external resin runner passes through a spiral concave trough which is changed from depth to shallowness to flow forwards by uniformly wrapping the central column, and finally flow out from a nozzle outlet by wrapping the internal layer resin, thus realizing the co-injection forming of two resins at the same time. The simultaneous co-injection forming device has the effects and the benefits of improving the shifting control currency of the device, improving the uniformity and the bonding strength of the external layer material and the internal layer material of the product, and solving the technical problem of the product which is produced by one-time forming at a single working position when the injection forming machine injects different external layer material and internal layer material. The core material can be high-strength recyclable material, thus meeting the requirement of energy-saving and exhaust-reduction.

The invention discloses a double-row pile supporting structure. The double-row pile supporting structure comprises front row piles and rear row piles, wherein front row crown beams are arranged at thetops of the front row piles, and rear row crown beams are arranged at the tops of the rear row piles; rigid-frame beams are arranged between the front row piles and the rear row piles; the front rowpiles, the rear row piles and the rigid-frame beams together form a plane truss structure; connecting web members vertically arranged at intervals are arranged between adjacent front row pile bodies and back row pile bodies; front row web members vertically arranged at intervals are arranged between adjacent pile bodies of the front row piles; and a spatial triangle truss column structure is formed between every two adjacent front row pile bodies and the corresponding rear row piles. According to the double-row pile supporting structure, the spatial triangle truss column structure supporting system with the pile bodies connected with the web members solves the existing problems of limited action effects of a dual-row pile spatial system and poor bending resistance of single-row piles, effective connection between the front row piles and the rear row piles is achieved, the space integrated structure is formed, lateral rigidity of the double-row piles is enhanced, and the bending resistance of the structure supporting system is improved.

The invention provides a tower-type porous air supply temperature control device for a data machine room, and the device comprises a temperature control chamber which is internally provided with a porous air supply channel located at a central position, and a tower-type rack disposed around the porous air supply channel; a hot air channel which is arranged above the temperature control chamber; aserver which distributed on the tower-type rack in a tower type, wherein a porous air supply channel upper top cover is arranged on the upper top surface of the porous air supply channel, a porous airsupply channel air inlet is formed in the lower bottom surface of the porous air supply channel, and porous air supply channel air outlets are uniformly formed in the surface of the porous air supplychannel. The problem of low space utilization rate is solved by the optimization of the space arrangement of equipment such as the server and a memory, and the air supply volume of the data machine room is reduced while the structure is compact, so the energy consumption of the fan is reduced, and the uniformity of air flow and temperature distribution in the machine room is improved by adoptingthe perforated plate for air supply.

The invention discloses a cooling pipe. The cooling pipe comprises a first spray nozzle, a second spray nozzle, an outer pipe and an inner guide pipe; the two ends of the first spray nozzle are through, the two ends of the second spray nozzle are through, the first spray nozzle and the second spray nozzle are coaxially arrayed to form an opposite portion with an annular water spraying port, the inner diameter of the second spray nozzle is larger than that of the first spray nozzle, and the annular water spraying port extends in the flowing direction of liquid to form a first containing cavity;the outer pipe is coaxially connected to the second spray nozzle, the inner guide sleeve is coaxially sleeved with the outer pipe, and a second containing cavity is formed in a hollow portion betweenthe inner surface of the outer pipe and the outer surface of the inner guide pipe; a first through hole for liquid to flow in is formed between the first containing cavity and the second containing cavity, and a second through hole for liquid to flow in is formed between the second containing cavity and the inner guide pipe.
