Meltblown Fabric Low-Temperature Cooling Device (Air Cooler)

Some reasons for meltblown fabric becoming brittle and hard
Uneven spinning, insufficient air volume from the air cooler! This causes uneven heat dissipation, generating internal stress leading to brittleness! It can be improved by adjusting the melt volume of the extruder, adjusting the temperature of the hot air blower, and increasing the air volume of the air cooler!

The meltblown fabric cooling air cooler produced by Baochiyuan has a large air volume and adjustable outlet temperature of 5-20 degrees, making it a great helper for solving your problems.

Detailed Introduction

Meltblown Fabric Low-Temperature Cooling Device (Air Cooler)

I. Working Principle of Meltblown Fabric Low-Temperature Cooling Device (Air Cooler)

According to the principle of the refrigeration system, the low-temperature, low-pressure liquid refrigerant exchanges heat with the surrounding air in the evaporator. The evaporator absorbs heat from the air, evaporating into a low-temperature, low-pressure gas. During the evaporation process, the refrigerant temperature remains unchanged. The low-temperature, low-pressure gaseous refrigerant enters the compressor, where it is compressed into a high-temperature, high-pressure gas. It then enters the condenser, where it exchanges heat with the indoor medium. Part of the heat from the high-temperature, high-pressure gas is absorbed by the medium, raising its temperature. The refrigerant releases heat and condenses into a high-temperature, high-pressure liquid in the condenser, with the temperature remaining constant during the condensation process. It then enters the expansion valve for throttling, which is a rapid cooling process. The refrigerant becomes a low-temperature, low-pressure liquid. After this process, the refrigerant re-enters the evaporator for heat exchange and evaporation, thus completing the entire refrigeration system cycle. This cycle continues continuously, allowing the air to be continuously cooled. The cooled air is then blown by the fan to the area requiring cooling.

II. Classification of Air Coolers

1. By Cooling (Heat Dissipation) Method

A. Water-cooled air cooler: (Shell and tube type) condenser equipped with a cooling tower for heat dissipation.

B. Air-cooled air cooler: (Finned type) condenser dissipates heat through the unit's own fan.

Air Cooler Selection: Generally chosen based on cooling capacity (air volume and temperature), selecting the appropriate water-cooled or air-cooled air cooler.

Characteristics of Air-cooled Type: Named after its heat dissipation method, it contains a finned condenser inside the unit for heat dissipation, eliminating the need for an additional cooling water tower. Installation and mobility are very convenient. However, it requires good ventilation in the workshop environment; otherwise, it will directly affect the cooling effect.

Characteristics of Water-cooled Type: Water-cooled air coolers require additional installation of a cooling water tower and a water pump to extract hot water for heat dissipation to achieve efficient cooling效果.
