Problems solved by technology

Among them, the corrugated plate water cooling type is to bend the metal plate into large corrugations in the horizontal direction, and form small corrugations in the vertical direction. The dehumidification liquid and treatment air are dehumidified in the upper and lower large corrugated channels, and the cooling water is taken away through the small corrugated channels in the horizontal direction. The latent heat generated by the dehumidification channel, this method has a compact structure and high efficiency, but there are problems such as non-hydrophilic metal materials, high price, poor corrosion resistance, and inconvenient channel isolation and sealing.

Embodiment 1

[0025] As shown in Figures 1 to 3, the heat and mass exchanger 1 of the present invention includes several plastic sheets 2 with oblique corrugations, and adjacent plastic sheets 2 are arranged alternately according to the corrugation direction, for example: the first layer of plastic sheets 2a and the second layer of plastic sheets The direction of corrugation of layer plastic sheet 2b is opposite, the direction of corrugation of the third layer of plastic sheet 2c is identical with the direction of corrugation of first layer of plastic sheet 2a, and so on. The two sides of each plastic sheet 2 are respectively bonded with the support frame 3 arranged on both sides, and the top and bottom of each plastic sheet 2 are respectively bonded with the support flat top 4 arranged at the top and bottom, and the support flat top 4 On the one hand, it is used as the reference plane during installation, and on the other hand, it is used as the interface between channels. On the left side...

Embodiment 2

[0028] In this embodiment, between every two layers of plastic sheets 2, only the passage in the same direction is kept unimpeded, such as: the passage of odd number or the passage of double number runs through, and another passage of double number or passage of single number is sealed, so that in the same passage exchange of the same nature.

Embodiment 3

[0030] In this embodiment, all passages between every two layers of plastic sheets 2 are kept unimpeded, that is, single-number passages and double passages are merged into one passage, and exchanges of the same nature are also carried out in the same passage.

[0031] As shown in Figures 2 and 4, in the above-mentioned embodiments, the corrugation angle α of the oblique corrugations on the plastic sheet 2 is the angle between the supporting flat top 4 and the oblique corrugations. If the corrugation angle α is too large, the water flow will be fast but The distribution is uneven, the corrugation slope angle is too small, and the water flow will be blocked when the water flow is slow. The best angle is to make the water form a thin liquid film on the surface of the plastic sheet 2, so the corrugation slope angle α is generally 25°~75°, The best range is 30°~60°. The wave height h of oblique corrugation is generally 4-9mm, and the optimal range is 5-7mm. If the wave height h is...

Abstract

The invention relates to a corrugated plate water evaporative cooling heat and mass exchanger, which is characterized in that the invention comprises a plurality of plastic sheets which are provided with twill weaves, the adjacent plastic sheets are mutually alternatively arranged according to the direction of the corrugation. The two sides of the plastic sheet are respectively bounded with supporting frames which are arranged on the two sides of the plastic sheet into a whole, and the top portion and the bottom portion of the plastic sheet are respectively bounded with a supporting flattop which is horizontally arranged on the top portion and the bottom portion of the plastic sheet into a whole. The invention can be widely applied to a cooling dehumidifying system of an air-conditioner. The positive and negative of each layer of corrugated plastic medium are alternatively bounded in the direction of the corrugation, which can not only exchange two different quality of humid heat in two channels simultaneously, but also utilize the heat exchange between the adjacent channels to cooling down the temperature when in dehumidifying. The invention has a good fluid distribution, the surface area S of the rate of heat and mass exchange can achieve 350-700m2 / m3, void ratio beta can achieve 90-95%. The invention can be widely applied in a new generation of dehumidifying evaporating cooling, or evaporating and indirect evaporating cooling air-conditioning systems.

Description

technical field [0001] The invention relates to a heat and mass exchanger, in particular to a corrugated plate water evaporation cooling type heat and mass exchanger. Background technique [0002] At present, people generally use air conditioners as the main tool for temperature and humidity adjustment, but air conditioners consume a lot of energy, have little fresh air, are prone to bacteria, and have serious cross-infection. In addition, indoor chemical decoration materials volatilize various toxic gases, resulting in deterioration of indoor air quality. It has become the focus of increasing attention that affects the physical and mental health of residents. Water evaporative cooling technology is one of the oldest cooling methods. In nature, when water evaporates adiabatically, it always takes away a large amount of latent heat. This part of latent heat can be converted from the sensible heat of the air, thereby reducing the temperature of the air itself for heatstroke pr...
