Detailed Description

Embodiments of the present utility model will be described below with reference to specific examples.

The utility model is explained in detail by the concrete implementation structure, which is as follows: referring to fig. 1, 2 and 3, the water collecting tray for the surface cooler of the fan coil unit provided by the embodiment of the utility model comprises a screw 1, a water leakage hole 5, a sealing strip 6, a water collecting tray 7, a clamping ring 14 and other accessories and connectors connected with the surface cooler;

when the air conditioner is assembled, the structure of the surface cooler 3 is the same as that of the prior art, and the upper panel 11, the water collecting tray 7, the front side plate 10 and the rear side plate 8 are respectively connected and fixed together through the screws 1 to form a box structure, wherein the air inlet part of the left box body of the surface cooler 3 is an air inlet 12, and the air outlet part of the right box body is an air outlet 8; the shell formed by the above components is placed in the water condensation plate 2 and is fixedly connected through the screw 1. When the water collecting tray 7 is manufactured, the water collecting tray is preferably formed by adopting a metal plate through processes such as bending, mould pressing, punching and the like, and the cross section structure of the water collecting tray is trapezoid or V-shaped.

In operation of the present utility model, as shown in FIG. 1, the airflow path direction is: the air flow sequentially flows through the air inlet 12, the surface cooler 3 and then is sent to corresponding use places through the air outlet 9;

when the utility model operates, the operating principle is as follows: condensed water generated by the surface cooler 3 is gathered in a rib rolling groove 13 in the bottom area of the trapezoid or V-shaped surface where the heat exchange fins of the surface cooler 3 are in contact with the water collecting tray 7, the rib rolling groove 13 is a concave arc-shaped semicircular groove formed by pressing the water collecting tray 7 downwards through punching equipment, and the arc radius of the rib pressing groove is 3-5 mm; the depth of the groove is 5-7 mm, and the groove has certain water storage and water storage functions; the condensed water is dripped into the condensed water tray 2 through the water leakage holes 5 arranged in the rib rolling grooves 13, and finally is discharged through the water outlet 4. The aperture and the number of the water dripping holes are determined according to the model of the fan coil unit, the length of the surface cooler and the humidity condition of the running environment, and the preferred size is 3-6 mm of the aperture of the water dripping holes; the pitch of the holes is 100-300 mm.

After the structure is arranged, the sealing strip 6 is arranged in the rib rolling groove 13, the sealing strip is a cylindrical or circular tube-shaped bar, the diameter is 4-6 mm, and the sealing strip 6 is made of light foam or plastic tube shell or rubber tube shell, the density of the sealing strip is less than that of water, and the density of the preferable material is about 1/2-1/3 of that of the water; when the amount of the condensed water is large, the sealing strip 6 floats above the condensed water to enable the water leakage hole 5 to be leaked in a naked manner so as to realize liquid discharge. The utility model arranges the concave arc-shaped rib rolling groove 13 at the air flow downstream position of the bottom of the air outlet end side of the surface cooler 3, when the unit operates, the condensed water is forced to be accelerated to drop into the condensate pan 2 by the water leakage hole 5 through the pressurization of the air flow, and finally is discharged through the water outlet 4.

The advantages and disadvantages of such a structure disclosed above are: when no condensed water exists in summer or heating operation is performed in winter, the sealing strip can overcome the lateral thrust of the airflow after flowing through the surface cooler 3 due to dead weight so as to avoid air leakage at the water dripping hole 5; however, when the condensed water is excessive, the sealing strip 6 may be impacted out of the rib groove 13, and in order to prevent the problems, the utility model fixes the sealing strip 6 by arranging a plurality of clamping rings. As shown in fig. 3, the clamping ring 14 is fixed with the water collecting tray 7 through the screw 1, and the sealing strip 6 is fixed in the rib rolling groove 13 and keeps a gap of 2-3 mm with the sealing strip 6 so as to prevent the sealing strip 6 from being separated from the rib rolling groove 13; at the moment, the central line of the sealing strip 6 in the length direction is 1-2 mm lower than the chord height dimension corresponding to the circular arc of the bar rolling groove 13; the sealing strip 6 can be ensured to seal the water leakage hole 5 in a natural state, and the water is restrained by the clamping ring 14 when the water flow is large.

The utility model has simple structure and convenient installation and use, and is an ideal water collecting tray of the surface cooler of the fan coil unit.
