Air Cooler hermeticity and tube box construction

Air Coolers are usually referred to as forced air cooling and water coolers for cooling with water as the cooling source. Most of the coolers that exchange heat with air require the addition of fins and can be used with the Table Air Cooling Fan, so let's take a look at the hermeticity and tube box construction of the Air Cooler. Here are some answers.

The Air Cooler's hermetic design solution.

The Air Cooler's gas-side over-flow channel should maintain a tight seal to prevent damage to the exhaust air volume. Its air permeability can cause uneven cooling of substances in the duct to teach and increased energy consumption of the centrifugal fan, etc. Because warm air leakage also continues to cause a partial circulation system of warm air, reducing the high efficiency of the Air Cooler. The sealing of the Commercial Air Cooler should therefore be given full attention, and the sealing of the Air Cooler includes the following dimensions: firstly, the sealing of the components themselves, the finned tube radiator on both sides of the tube should be connected to the barrel, and a windshield should be added to the upper and lower sides to avoid gas leakage; the distance between the centrifugal impeller and the blowing barrel should not exceed 0.5% of the diameter of the centrifugal impeller. Secondly, the hermeticity between the components, the contact area between the blowing barrel, the wind frequency, the pipe teaching, and the blinds should avoid a gap, otherwise, the hermeticity should be carried out. When the gap between the tube teaching and the structure, the blowing barrel, and the expansion tank is lower than 5mm, a soft rotary seal can be used for hermeticity.

Description of the construction of the Air Cooler tube box.

The Air Cooler tube box is one of the main components of the Air Cooler and its structural form determines the pressure resistance of the Air Cooler. This is easy to form, easy to produce, easy to work with, and has a good working capacity under pressure. The disadvantage is that the connection between the heat exchanger tube and the barrel is made by deep hole welding, which makes it difficult to control the welding quality. The total number of wire plugs is high and the machining accuracy is difficult to ensure, thus the seal is not strong. Second, combined with the column tube type tube box. The Characteristic is to bear the pressure working ability is good, but loading and unloading handling and testing complicated, heat transfer tube head maintenance difficult. Third, is the cover plate-type flange tube box. Characteristic is that the quality of the heat transfer tube head of the tube box is easy to ensure, and easy to repair, but because of the choice of removable gaskets to complete the sealing, the processing accuracy of the protruding surface is high, and the pressure bearing capacity is low.
