How can the air cooler be installed for optimum cooling?

In hydraulic engineering machinery, the air cooler generally adopts an aluminum plate fin cooler which is structured like an engine cooling water tank.

According to the thermal principle, there are two main factors affecting the heat dissipation effect: (1) heat dissipation area; (2) air flow rate. In practice, other heat dissipation methods can be fully utilized to enhance the cooling effect. Specific to other types of products in the same industry, when a certain machine is determined by structure, position, etc., the area of the cooler is basically determined. To improve the cooling effect, the flow rate and direction of the air are the focus.


A comprehensive range of mechanical equipment coolers can be installed: the air cooler can be mounted in a flat or vertical position.


In the case of paperback, the drive mechanism (motor or hydraulic motor) can be placed in the upper or lower part of the air cooler; for the cooling direction, the mechanism recooler can be driven first, or vice versa; depending on the temperature difference between the equipment and the environment, design and manufacture The focus of consideration.


The vertical installation method mainly considers the direction of the hot air to be taken away by the air cooler, so the degree of freedom of installation is large as long as the hot air does not affect other components or the motion characteristics conflict. The vertical installation is generally installed on the equipment with the outer casing protection. When the machine is running, the internal temperature of the equipment is higher than the external temperature, and the heat of the cooler is radiated through the surface of the radiator. At this time, if the external cooling air is from top to bottom, the radiator is removed. Due to the cooling of the wind speed, the convection heat is also well utilized, and the heat absorption of the radiator is utilized. This type of installation has its advantages: when the dust in the construction environment air is serious, it can effectively prevent the dust from being adsorbed on the air cooler fins and reduce the heat dissipation effect.


To sum up: To achieve a good cooling effect of the air cooler, first try to use the largest heat dissipation area; secondly, increase the cooling air speed; again, it is combined with other methods as much as possible.
