The invention discloses a novel vacuum-tube type solar collector in the field of the solar collectors. The novel vacuum-tube type solar collector comprises a cold-water tank and a hot-water tank through a plurality of vacuum collector tubes. The cold-water tank and the hot-water tank are mounted on a bracket. The hot-water tank is disposed at the top end of each vacuum collector tube, and a hot-water outlet is formed on the top portion of the hot-water tank. The cold-water tank is disposed at the bottom end of each vacuum collector tube, and a cold-water inlet is disposed on the cold-water tank. An opening is formed at each of two ends of each vacuum collector tube, the upper end of each vacuum collector tube is inserted into a hot-water tank device, and the lower end of each vacuum collector tube is inserted into a cold-water tank device. Provided with the cold-water tank and the hot-water tank at the same time, the novel vacuum-tube type solar collector is simple in structure. The whole heat-collecting process is good in flowing characteristic, the hot-water outlet is high in temperature and easy to regulate, and therefore novel vacuum-tube type solar collector is applicable to occasions with water continuously flowing in and out.

The invention discloses a flow electroporation device and a system. The system comprises a flow electroporation device, an injection pump and a voltage source, wherein the flow electroporation device comprises a substrate, electrodes arranged on the substrate, a channel for limiting fluid to flow, a top cover of an inlet and an outlet of fluid, the electrodes are arranged in a crossing way; each pair of electrodes comprise an anode and an cathode which are oppositely arranged, and the channel is arranged on the electrodes; the top cover is arranged above the channel, and the injection pump isconnected to the inlet and the outlet of the top cover in the flow electroporation device through a pipeline and is used for controlling the flow rate of the fluid; and the voltage source is connected with the electrodes through electric connecting pieces and is used for setting and producing pulse voltage. The flow electroporation system utilizes the fluid channel and the injection pump connected with the fluid channel to realize the continuous flow of various suspensions in the fluid channel, so that the fast treatment of a large number of samples can be continuously realized in the processthat cells are electroporated.

The invention discloses a countercurrent solid-state distillation tower with a spiral slide, which belongs to the field of biological energy technology and process equipment. A steam chamber is arranged at the bottom of the tower body, and a steam distributor is used to isolate the steam chamber from the tower body, and the spiral slide is fixed. Installed on the inside of the tower body and above the steam chamber, there is a central conduit in the center of the tower body, which is inserted directly into the bottom of the tower and isolated from the steam chamber; the gas outlet of the central conduit is connected to the vacuum pumping device, and the central conduit There is an air outlet on the upper part of the tower, and the stripped steam enters the central conduit from the air outlet and is discharged out of the tower; a spiral slide is installed on the inner wall of the tower body. The structural design of the spiral slide used in the present invention can realize the continuous flow of solid granular materials and full contact with steam, so that the solid-state distillation process can realize continuous production and improve production efficiency; and the residence time of materials in the tower can be controlled, both It not only takes into account the advantages of simple operation of batch distillation, but also ensures the need of continuous production.

The invention relates to an intelligent digital set top box with an efficient cooling function. The intelligent digital set top box comprises a body. The body comprises a water storage tank, a water inlet pipe, a water outlet pipe and a set top box. A circuit board, a PLC and a cooling mechanism are set in the set top box. A water storage mechanism is set in the water storage box. The cooling mechanism comprises a cooling pipe, a reciprocation plate, a reciprocation assembly and a plurality of abutting assemblies. Each abutting assembly comprises a first motor, a first drive shaft, a bushing and an abutting block. The water storage mechanism comprises a clapboard, a circulation assembly and a backflow assembly. According to the intelligent digital set top box with the efficient cooling function, through utilization of the cooling mechanism, the cooling pipe abuts on the circuit board, the cooling pipe is driven to move, and water solution in the cooling pipe absorb heat at each part ofthe circuit board, so the cooling is realized. Through utilization of the water storage mechanism, the opening and closing of the water inlet pipe is controlled. Through utilization of a first waterpump, the water solution flows into the cooling pipe continuously, so the cooling capability is ensured, a cooling effect is improved, and the practicability of equipment is improved.

The invention discloses a cotton-thread-based passive micro-fluid fuel cell, which comprises an anode carbon paper and a cathode carbon paper; the cotton-thread-based passive micro-fluid fuel cell is characterized in that a first cotton thread and a second cotton thread are arranged on the anode carbon paper and the cathode carbon paper; the first cotton thread and the second cotton thread are isolated by a third cotton thread; one end of the first cotton thread is inserted to a first inlet culture dish, anode electrolyte is stored in the first inlet culture dish; one end of the second cotton thread is inserted to an inlet culture dish, and cathode electrolyte is stored in a second inlet culture dish; one end of the third cotton thread inserted to a third inlet culture dish, and isolating liquid is stored in the third inlet culture dish; the other ends of the first cotton thread, the second cotton thread and the third cotton thread are inserted to an outlet culture dish; the faces where the anode carbon paper and the cathode carbon paper are in contact with the cotton threads are coated with an anode catalyst layer and a cathode catalyst layer. By means of the capillary force of the cotton thread and the gravity, the continuous flow of the cathode fluid and the anode fluid is realized. The cotton-thread-based passive micro-fluid fuel cell can be widely applied to energy source, chemical industry, environment-friendly, and other domains.
