Problems solved by technology
[0003] Although the dew point indirect evaporative cooling technology can reduce the air temperature below the wet bulb temperature, the existing dew point plate-fin indirect evaporative cooler is based on the ordinary evaporative cooler, and only the air side and the flow channel of the heat exchanger have been modified. Improvement, the heat exchange efficiency is low, and there is still a certain gap between the treated air temperature and the dew point temperature, and further optimization design is needed

Embodiment Construction
[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] figure 1 The structure of an embodiment of the indirect evaporative cooler of the present invention is shown, including a plate-fin cooler core, a direct evaporative cooler and a water supply device. The core of the plate-fin cooler is composed of a pre-cooling section A and a cooling section B. The direct evaporative cooler C is set on the upper part of the pre-cooling section A of the plate-fin cooler, and the upper part of the pre-cooling section A of the plate-fin cooler core is ventilated The air pipe 6 connected at the mouth communicates with the direct evaporative cooler C. The water supply device is composed of pre-cooling section, cooling section, direct evaporative cooler, water storage tank, water pump, water distributor and so on.

The invention discloses a porous functional ceramic dew point plate-fin indirect evaporative cooler, comprising a plate-fin indirect evaporative cooler, the cooler module is composed of a plate-fin cooler module precool section and a plate-fin cooler module cooling section, a direct evaporative cooler is arranged on the upside of the plate-fin cooler module precool section, the upside of the plate-fin cooler module precool section intercommunicates with the bottom of the direct evaporative cooler through an air duct. The evaporative cooler of the invention implements a heat and moisture exchanging with a secondary air near the dew point through the water near the air dew point, which makes the out wind temperature approach to the dew point further and the water scatter more uniformity, the heat and moisture exchanging efficiency is enhanced largely.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration, and relates to an evaporative cooler suitable for air-conditioning, in particular to a porous functional ceramic plate-fin indirect evaporative cooler capable of reducing the air temperature to a temperature close to the dew point. Background technique [0002] In recent years, air conditioning, as an effective means to adjust the indoor environment and air quality of buildings, has achieved unprecedented rapid development. However, due to the shortage of energy and the increase of air-conditioning energy consumption, coupled with the increasingly serious environmental pollution and the improvement of people's requirements for living comfort, there is an urgent need to develop energy-saving, environmentally friendly, healthy and economical air-conditioning and refrigeration equipment. Evaporative cooling technology has become an important direction in the field of air c...
