Double-purpose radiating fin system for refrigeration and heating

Abstract

The invention relates to the field of heating, ventilation and air conditioning and particularly discloses a double-purpose radiating fin system for refrigeration and heating. The double-purpose radiating fin system comprises a porous medium heat radiating unit, a metal heat radiating unit and a condensed water collecting device, wherein the porous medium heat radiating unit is arranged directly facing an environment and human bodies in a room, the metal heat radiating unit is arranged between the porous medium heat radiating unit and a wall body, and the condensed water collecting device is arranged at the lower part of the porous medium heat radiating unit and/or the lower part of the metal heat radiating unit. Under the working condition of refrigeration, condensed water on the porous medium heat radiating unit is absorbed by the main body of the porous medium heat radiating unit, and condensed water on the metal heat radiating unit is guided into the condensed water collecting device under the action of gravity and is further drained. The problem about the condensed water in the prior art is overcome without reducing the heat transferring efficiency of radiating fins, and indoor humidity can also be automatically regulated.

Description

technical field [0001] The invention relates to the field of heating, ventilating and air-conditioning, in particular to a cooling and heating radiator system. Background technique [0002] Indoor radiators, also known as radiators, are a common heating device for buildings. Heat sinks can be divided into cast iron heat sinks, steel heat sinks, copper-aluminum composite heat sinks according to different materials; according to different shapes, they can be divided into column type, plate type, fin type, etc. Radiating fins are widely used in winter heating due to factors such as energy saving, little impact on indoor humidity, and convenient installation. [0003] However, the existing cooling fins can only be used for heating in winter. In summer, when the air temperature near the refrigeration equipment is lower than the dew point temperature, the water vapor in the air will condense on the surface of the refrigeration equipment to form condensed water. The condensed wat...

[0003] However, the existing cooling fins can only be used for heating in winter

In summer, when the air temperature near the refrigeration equipment is lower than the dew point temperature, the water vapor in the air will condense on the surface of the refrigeration equipment to form condensed water. The condensed water will affect the heat transfer efficiency of the heat sink surface, and it will also cause mildew and affect the indoor environment.

Another important restrictive factor for heat sink cooling in summer is the low efficiency caused by the temperature difference of water supply
