It should be noted that the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
Referring to fig. 1 to 3, an embodiment of the present invention provides a condensation-proof cold radiation system with a dehumidification system, which includes a dehumidification system, an air outlet 1 connected to the dehumidification system, and a cold radiation plate 2; wherein, the dehumidification system comprises an air inlet fan, a ventilation pipeline 3 and a dehumidifier; a plurality of ventilation pipes 3 are arranged in parallel; the air inlet fan and the dehumidifier are respectively arranged at the air inlet end of the air exchange pipeline 3; the plurality of air outlets 1 are arranged on both sides of the ventilation duct 3 along the extending direction thereof; the cold radiation plate 2 is installed in the side of the ventilation pipeline 3, the installation direction of the cold radiation plate is just opposite to the air outlet 1, and the air outlet direction of the air outlet 1 is parallel to the plate surface of the cold radiation plate 2, so that dry fresh air forms an air curtain on the surface of the cold radiation plate 2.
Different from the prior art, the utility model discloses directly blow off dehumidification system's dry air to cold radiation board 2's surface, form the air curtain, the air humidity who reduces cold radiation board 2 surfaces continuously locally prevents effectively that the condensation. The dryness of the air blown out by the dehumidification system is ensured by the dehumidifier. Moreover, the process is very rapid, and only tens of seconds or even seconds are needed after the dehumidification system is started, so that a local dry environment can be created on the surface of the cold radiation plate 2, and the cold radiation plate 2 can rapidly work with high cooling power at the initial starting stage. Therefore, on one hand, the comfort of indoor cooling is improved, and the indoor temperature can be cooled more quickly; on the other hand, the energy loss is reduced. The utility model discloses a dehumidification system mainly is applied to the cold radiation board and starts the initial stage, and after the new trend system gradually reduces the humidity of room air to the setting value like prior art, dehumidification system need not work again, and the optional is closed.
The air of the air curtain slowly falls to the ground from the cold radiation plate 2 along with the reduction of the flow speed, and indoor air circulation is formed. The process has no wind feeling, the human body can not feel obvious air flow, and the comfort is higher. And the dehumidification system belongs to an auxiliary system that is different from the new trend system outside, and its air that blows off, its own temperature is lower, and in-process when its slowly descends to ground also helps indoor cooling through the heat convection effect. In addition to the conventional flat design, the outer shape of the cold radiation plate 2 can also be preferably curved inward or outward, which also corresponds to the hydrodynamic principle described above.
It should be noted that the cold radiation plate 2 of the present invention is not necessarily used as a ceiling but may be vertically installed as a wall panel. The utility model discloses a cold radiation system also has use value in the half empty wall more than liftoff 2 meters, theory of operation with as when the ceiling equivalence.

The air curtain formed by the dry air blown out by the dehumidification system also applies the principle of hydrodynamics. The dry air blown out from the air outlet 1 flows along the surface of the cold radiation plate 2, and the fluid itself has viscosity, and can generate adhesion on the surface of the cold radiation plate 2 to form a boundary layer. Therefore, the drying air blown out through the outlet port 1 does not require a too high flow rate. When the air outlet 1 is arranged right, the dry air is blown out oppositely, meets the cold radiation plate 2 near the middle part, then the flow speed is reduced, the dry air is diffused to the periphery, and then the dry air slowly descends.

Since the specific structure of the cold radiation plate 2 is different from the prior art, it is illustrated in the drawings of the specification by omitting schematic drawings.
It should be noted that although the liquid-cooled heat source is the mainstream of the current cold radiation system, it is not excluded to use other solid-state heat sources. If the peltier effect is currently used in research and development, the solid-state refrigerating device which generates temperature difference by electrifying two conductors can also be used as a cold source of the utility model.
Example two
The difference between this embodiment and the first embodiment is the arrangement of the air outlets 1, and according to the fluid mechanics principle, the flow of the drying air produces different effects.

At this time, the opposite side of each air outlet 1 is not provided with another air outlet 1 which is arranged oppositely, and the sprayed drying air can not influence the flowing of the drying air coming oppositely. The dry air ejected from each air outlet 1 forms an air channel, and the flow directions of the adjacent air channels are opposite. The drying air flowing toward each other at the adjoining boundary of the adjacent wind tunnel slows down the flow rate and forms a swirling turbulence. The swirling turbulence stays in the middle of the cold radiation plate 2 for a longer time, becoming a part of the air curtain. Until a portion of the kinetic energy of the drying air in the turbulent flow is exhausted, the flow rate is further slowed down, and this portion of the drying air slowly descends to the ground.
This scheme is applicable to the less occasion of interval width is arranged to ventilation duct 3, and can further reduce the initial velocity of flow of dry air through 1 spun in air outlet, can reduce the quantity that sets up of air outlet 1 again.

And the air curtain is formed by applying the fluid mechanics principle, and the dry air blown out by the dehumidification system through the air outlet 1 is attached to the surface of the cold radiation plate 2. The dry air of air curtain forms heat convection with cold radiation board 2, finally slowly descends to indoor nearly ground surface, starts the auxiliary air circulation of initial stage at the system, not only improves the cooling efficiency, and does not have the sensation of wind, and the travelling comfort is strong.
The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention.
