The structure of fan frame includes a channel to induct airflow from an opening to another opening. Inner circumference wall pathway of at least one opening is extended and outspread towards outside along radial by using the axis of the heat sink or channel as center in order to increase air effluent or influent area. Thus, in and out air quantities are increased largely without need of changing other assembling condition so as to raise heat dispersion.

An electronic device comprises a shell. The shell comprises two opposite side walls, a first end wall and a second end wall, wherein the first end wall and the second end wall are opposite. A first partition and a second partition are arranged between the first end wall and the second end wall at intervals, a plurality of first fans are fixed to the middle of the second partition, a plurality of second fans are fixed to two ends of the second partition, air flow generated by the first fans and the second fans is opposite in direction, the first end wall, the first partition and the second end wall are respectively provided with a plurality of vent holes, the first fans lead the air flow into the space between the first partition and the second partition from the vent holes of the first end wall and the first partition and lead out the air flow from the vent holes in the middle of the second end wall through the second partition, and the second fans lead the air flow into the space between the first partition and the second partition from the vent holes in two ends of the second end wall. As the air flow generated by the first fans and the second fans of the electronic device is opposite in direction, the air flow generated by the first fans and the second fans within unit time is increased, and the radiating effect of the electronic device is improved.

An embodiment of the present invention provides an electronic device, wherein the electronic device is a portable computer or a tablet computer, and the electronic device includes: a main body, including a casing and at least one functional module arranged in the casing, on the electronic device A bracket is also provided, and the bracket is connected to the casing, wherein the body can be placed on a plane through the bracket; the detector is arranged in the body, and the detector includes a first detection subunit for obtaining a trigger information , and determine whether the trigger information satisfies the preset condition, and generate a first determination result; the first adjustment member is connected to the bracket, and adjusts the position and / or height of the bracket according to the first determination result, thereby increasing the heat dissipation space of the electronic device , improve the heat dissipation speed of the electronic equipment, and can select the corresponding heat dissipation space according to the heat dissipation conditions, and improve the heat dissipation effect of the electronic equipment.

The invention discloses a nitration reactor for producing p-nitrotoluene from toluene, which comprises a reaction kettle and an agitation reinforcement assembly, the agitation reinforcement assembly is installed in the reaction kettle, and the agitation reinforcement assembly plays the role of enhancing the uniformity of material stirring in the reaction kettle , in the present invention, under the action of the upward carrying force and centrifugal force of the auger, the material will be continuously thrown upwards obliquely, and the thrown material will be blocked by the spiral heat exchange plate and then squeezed along the bottom surface of the spiral heat exchange plate. Falling down obliquely, and the agitating blades of the helical heat exchange plate and the auger are helical, so that the materials at different depths of the reactor can be subjected to the double mixing effect of extrusion and stirring, which greatly improves the mixing degree of the materials. It is beneficial to improve the generation of nitrate. The present invention installs a spiral heat exchange plate in the reaction kettle, and a heat exchange channel is opened inside the spiral heat exchange plate, which is convenient for heat exchange with the reactants in the reaction kettle to achieve the effect of cooling, and the low temperature is conducive to Nitrate formation.

The invention discloses a ventilation control system for a laboratory. The system comprises a main air inflow pipe, an air inflow pipe branch, an air inflow device, a main exhaust pipe, an exhaust pipe branch and an exhaust device and is characterized in that an air adjusting heat exchange segment used for adjusting the air flow and heat exchange is arranged on the exhaust pipe branch and located in the air inflow pipe branch; the air adjusting heat exchange segment comprises a connecting shaft, a first torque motor, a rotating bearing, a gear sleeve, a transmission gear set and connecting cylinders, and the connecting cylinders are sequentially arranged from left to right. In the rotating process of a plurality of inner air adjusting heat exchange fins, a spiral channel can be formed, the size of the channel and the size of an opening of the channel change regularly, and therefore the air flow of the exhaust pipe branch can be adjusted, and in a similar way, the air inflow of the air inflow pipe branch can be adjusted; in the rotating process of the inner air adjusting heat exchange fins, the contact area of air in the channel and the inner air adjusting heat exchange fins is unceasingly increased, and therefore heat exchange between the exhaust pipe branch and the air inflow pipe branch can be achieved through the inner air adjusting heat exchange fins and outer air adjusting heat exchange fins, and the temperature difference of air in the exhaust pipe branch and air in the air inflow pipe branch is reduced.

The invention discloses an air outlet method for realizing a front-blade-free automobile air conditioner, which comprises the following steps that: 1) original air at an air outlet passes through an air door to realize the first adjustment of the air direction, and the air door realizes the adjustment of the upward or downward air direction of the original air; 2) the wind direction is guided to the edge of a shell when the adjusted wind direction passes through a rib structure; and 3) the guided wind direction flows to the inner side of the arc-shaped or circular shell, and the final wind outlet angle of the wind direction is realized through the reflection of the wind direction after the wind is blown to the shell. According to the air outlet method, the structural design of front and rear blades in a traditional middle air outlet mechanism in the prior art is thoroughly changed, front blades are omitted, up-down and left-right air direction adjustment can be conveniently achieved, the problems are solved that the front blades frequently swing and get loose, and the front blades influence the air speed and the air volume.
