Forced convection device for tube-and-fin radiator

Abstract

The invention belongs to the field of radiator device equipment, and particularly discloses a forced convection device for a tube-and-fin radiator. The device consists of fins, heat pipes and guide rudders; a plurality of forming holes are punched in parallel fins according to the position structures of the heat pipes, so that the heat pipes are arranged in the forming holes in a sleeving manner for fixing; the guide rudders are symmetrically and fixedly mounted on the two side walls of each heat pipe; the guide rudders are low-resistance aircraft airfoil profiles and are mounted at certain angles; the sum of the mounting angles of the two symmetrical guide rudders on the two sides of each heat pipe is 360 degrees; air among the fins can form two air helixes which are parallel to each other and are in the same rotating direction in the vertical direction; forced convection is formed at the tangent part of the two air helixes. According to the forced convection device disclosed by the invention, a heat exchange effect of wall surfaces of the heat pipes as well as the fins and the air is strengthened on the basis of ensuring normal flow of the air; meanwhile, the rotating of the air in flow channels is realized through the mounting directions, so that the air in adjacent two flow channels rotates in the same direction, forced air convection is realized, and the radiator can adapt to the change of a variety of conditions.

Description

technical field [0001] The invention belongs to the field of radiator equipment, and more specifically relates to a forced convection device for a tube-fin radiator, which can improve the working performance of the radiator of the engine cooling system in the engine compartment of an engineering vehicle. Background technique [0002] Because diesel engine has a series of advantages such as low speed, high torque and high power, it is widely used as a power source in engineering vehicles. Since diesel is used as its main energy source, the heat brought by fuel combustion needs to be dissipated to the environment in time. The role of the engine cooling system is to ensure that the cylinder temperature of the diesel engine remains within a reasonable range. If the cylinder temperature is too high, the oil film seal will be damaged, and even "burning cylinder" will occur; if the cylinder temperature is too low, there will be The combustion efficiency is low, and the fuel consum...

Problems solved by technology

In current product design, the heat pipes of tube-fin radiators are usually flat tubes. However, with the continuous improvement of vehicle design requirements, its application is usually limited by the fixed structure, and the effect is limited.
