Technical realization elements of engine box integrated gas flow distribution device

Technical realization elements:

3. The purpose of this utility model is to provide an engine box-type integrated gas flow distribution device, so as to overcome the disadvantages of poor stable air pressure and high temperature of the air flow conveyed by the air intake pipe of the existing engine.

4. In order to achieve the above object, the present utility model provides an engine box type integrated gas flow distribution device, including: an upper box provided with an air inlet, which is connected with an air inlet pipe; a middle box, which Is arranged below the upper box, the top surface of the middle box and the bottom surface of the upper box are communicated through a plurality of first through holes arranged at intervals; the cooling core is detachably installed on the In the middle box; and the lower box, which is arranged below the middle box, the top surface of the lower box and the bottom surface of the middle box are connected by a plurality of second through holes arranged at intervals, and the lower box An air outlet is provided on the front side or the rear side.

5. Preferably, in the above technical solution, the air inlet is arranged on the left side or the right side of the upper box.

6. Preferably, in the above technical solution, the number of the air outlets of the lower box corresponds to the number of cylinders of the engine one-to-one, and all the air outlets are spaced apart along the left and right directions.

7. Preferably, in the above technical solution, a mounting hole is respectively provided on the left and right sides of the middle box, the cooling core is arranged transversely between the two mounting holes, and the cooling core is connected to the Each of the mounting holes is connected by a mounting flange.

8. Preferably, in the above technical solution, the cooling core includes a cooling water inlet, a cooling water outlet, and several groups of cooling tube groups, and two ends of each group of the cooling tube group are respectively connected to the cooling water inlet and the cooling water The cooling water outlet is connected, and all the cooling tube groups are spaced apart along the up and down direction. Each group of the cooling tube groups includes a number of cooling tubes spaced apart in the front and back direction. The cooling pipes are staggered.

9. Preferably, in the above technical solution, the upper box, the middle box and the lower box are integrally formed.

10. Compared with the prior art, this utility model has the following beneficial effects:

11.1. The upper box of the gas flow distribution device of the present invention is a gas diffusion and preliminary surge tank, the middle tank is a cooling exchange and secondary surge tank, and the lower tank is a tertiary voltage stabilizer and air flow distribution tank, which is compressed after pressurization. The gas diffuses and achieves primary voltage stabilization, and then flows into the middle box through the first through hole, exchanges heat with the cooling core in the middle box to realize gas cooling, and realizes the second voltage stabilization in the middle box, and finally passes through the lower box For the third time of stabilization and delivery, the gas is delivered to the engine's air intake system through the air outlet of the lower box to provide the engine with gas with stable pressure and suitable temperature, which facilitates the combustion of the engine and reduces fuel consumption.

12.2. All the cooling tube groups of the present invention are spaced in the vertical direction, and the cooling tubes of the two adjacent groups of cooling tube groups are staggered and distributed, so that the air flow can change the direction of the air flow and increase in the process of flowing in the up and down direction. The heat exchange area between the large airflow and the cooling pipe.
