Description
Technical Field
The utility model relates to a heat insulating layer containing polyurethane; the utility model discloses still relate to a device that contains polyurethane, for example an air conditioner water collector.
Background
In an air conditioning system, a heat exchanger generates condensed water in the working process, and a traditional solution is to arrange a water pan below the heat exchanger so as to lead out the condensed water. However, since the temperature of the condensate is generally low (typically lower than the operating environment), the accumulation of the condensate in the drip tray may cause the temperature of the drip tray to drop, which in turn causes the hotter water vapor in the operating environment to condense on the cooler outer surface of the drip tray, eventually resulting in the condensate hanging outside the drip tray. This phenomenon is commonly referred to as secondary condensation in air conditioning systems. Because the condensed water that the secondary condensation produced hangs outside the water collector, consequently can't be derived by the water collector. If the air conditioning system is used for a long time, the condensed water may accumulate in the system and cause the interior of the product to be wet, thereby causing corrosion or sanitation problems and reducing the use experience of the product. Therefore, it is necessary to add a heat insulating layer to the water collector to enhance the heat insulating performance of the water collector, thereby preventing secondary condensation.
The conventional water collector heat insulation layer is Polyethylene (PE) sponge, uses the polyethylene sponge gets up in order to form the heat insulation layer with water collector base body periphery is enclosed, prevents the secondary condensation. Generally, the polyethylene sponge is manually cut and then manually attached to the base body of the water pan. Due to the requirement of the drainage function of the water receiving tray and the limitation of the design space, the geometric structure of the water receiving tray is generally complex. This makes the manual application of the polyethylene sponge more difficult. Therefore, in the actual production process, the polyethylene sponge heat-insulating layer manually attached consumes manpower and wastes materials, and the attaching effect is not ideal, so that the phenomenon of glue failure or separation is easy to occur.
In order to solve the above technical problems, various measures have been proposed. Chinese patent CN206113266U discloses an insulating layer of an air conditioner, which can be used for a water pan. The heat insulation layer is of a double-layer sponge structure. The first sponge layer is arranged on the outer side of the water pan base body and mainly plays a role in heat insulation. And the second layer is arranged on the outer side of the first sponge layer and is directly contacted with air, and is mainly used for blocking moisture in the air. And an adhesive for connection is arranged between the first sponge layer and the water pan base body and between the first sponge layer and the second sponge layer. The first and second sponge layers may be Polyurethane (PU) foam. Compared with the traditional technical scheme, the technical scheme improves the heat insulation performance and the water insulation performance of the heat insulation layer, but does not solve the problems of material waste and manpower consumption in the traditional technical scheme. In addition, the production process is complicated due to the multilayer structure and the application of the adhesive. Finally, the adhesive may also cause the problem of exceeding the Total Volatile Organic Content (TVOC).
Chinese patent CN209431632U discloses a water pan, which has a heat preservation cavity structure. The heat preservation cavity structure is formed by enclosing an inner plate and an outer plate of the water receiving plate, and heat preservation materials are filled in the heat preservation cavity and can be polyurethane foam. Chinese patent CN203413796U discloses a water pan similar to CN209431632U, which also has a thermal insulation cavity structure. The two patent applications all solve the problem of extravagant material, consumption manpower among the traditional technical scheme through the mode that changes the water collector structure. But the cavity structure of the water pan improves the structural complexity of the water pan, further complicates the production process and reduces the production efficiency.
Chinese patent CN201731600U discloses a water pan with a heat insulating layer, which is made of polyurethane foam. The heat insulation layer is arranged on the inner wall of the water pan base body and is in direct contact with the condensed water. Meanwhile, in order to enhance the heat insulation performance of the water pan, a layer of heat insulation cotton is arranged between the heat insulation layer and the water pan base body. Arrange the inside of water collector in with adiabatic layer, solved extravagant material among the traditional technical scheme, consumed the problem of manpower. However, since the condensate is in direct contact with the insulation layer, the design places extremely high demands on the water-resistant and water-barrier properties of the insulation layer. Although the integrally formed polyurethane insulation layer reduces the structural complexity of the drip tray to some extent, the multi-layer laminated structure is still not suitable for mass production.
Chinese patent CN201944997U discloses a V-shaped water pan, which comprises an inner plate and an outer plate. A heat insulation cavity structure is enclosed between the inner plate and the outer edge, and polyurethane foam can be filled in the heat insulation cavity to ensure the heat insulation performance of the water pan. The main innovation point of the V-shaped water pan is that the inner plate and the outer plate are both V-shaped so as to ensure the smoothness of drainage. Similar to the water pan with the cavity structure, the embodiment also has the problems of complex production process and low production rate.
In summary, there is a need to develop a heat insulating layer suitable for a water pan of an air conditioning system, which has strong heat insulating capability, strong water resistance and water isolation capability, small pollution, simple structure and process, manpower and material saving, and easy production, so as to solve the current technical problems.

Or the air-conditioning water pan is in a round basin shape, the radius of the bottom is 0.075m, the radius of the top (namely the opening part) is 0.10m, and the height of the side plate (according to the vertical distance between the bottom and the top) is 0.10 m. Coating a polyurethane layer with the thickness of 7 mm on the substrate; after foaming, the polyurethane core density (i.e., the density at 3.5mm in the thickness direction of the polyurethane layer) was 22.6kg/m3The overall density of the polyurethane layer was 37.0kg/m3And the surface is compact.
Fig. 4a shows a schematic cross-sectional view of a preferred embodiment of an air conditioner water pan base 302 with voids in the surface. In order to prevent the condensed water from penetrating through the air-conditioning water pan 300, the gap does not penetrate through the air-conditioning water pan base 302. Because the gap on the surface of the air-conditioning water pan base body 302, the polyurethane layer 301 can protrude in the foaming process to form a bulge and enter the gap on the surface of the air-conditioning water pan base body 302, so that the polyurethane layer 301 and the air-conditioning water pan base body 302 form a riveting structure, and firm combination is formed. Although the gaps on the surface of the air conditioning drain pan base 302 are uniformly distributed in fig. 4a, it should be noted that the gaps on the surface of the air conditioning drain pan base 302 may be non-uniformly distributed.
Fig. 4b is a partially enlarged schematic view of the surface gap of the air-conditioning water pan base 302 shown in fig. 4 a. In order to enhance the bonding of the polyurethane layer 301 and the air-conditioning water-receiving tray base 302, the inner surface of the gap 305 that does not penetrate the air-conditioning water-receiving tray base 302 is rough, for example, has grooves, wherein the groove 305c opens toward the polyurethane layer, and the grooves 305a and 305b do not open toward the polyurethane layer. Thus, when the polyurethane is foamed, the protrusions of the polyurethane layer 301 extend into the grooves 305a and 305b, and then the connection strength between the polyurethane layer 301 and the air-conditioning water pan base body 302 can be further enhanced.
It should be noted that the description of fig. 4a-4b with respect to the substrate surface voids and grooves therein applies equally to the aforementioned thermal insulation layer.
While various preferred embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and changes may be made without departing from the scope of the invention as defined in the appended claims.
