Description

Technical Field

[0001] The utility model belongs to the technical field of composite boards, and particularly relates to a novel anti-cold bridge rock wool composite board specially used for various dehumidifiers. Background Art

[0002] In the field of industrial air conditioning, the panel is an important component of air conditioning insulation, and the performance of the air conditioning unit is usually determined by the panel.

[0003] There are two types of air conditioning panels commonly used on the market:

[0004] 1) Polyurethane foam board: It usually consists of two layers of metal sheets inside and outside to form a cavity. AB material (polyurethane foam material) is injected for chemical reaction to fill the cavity and achieve the purpose of insulation.

[0005] 2) Rock wool insulation board: It usually consists of two layers of metal sheets inside and outside the cavity, and the purpose of insulation is achieved by filling it with rock wool.

[0006] However, in actual use, it is found that the two existing air conditioning panels still have the following problems:

[0007] 1) The polyurethane used in polyurethane foam boards is not easy to degrade, so it pollutes the environment greatly. More and more countries and regions are gradually abandoning panels and products that use polyurethane as thermal insulation materials. If polyurethane foam boards continue to be used as the thermal insulation structure of air conditioners, it will seriously affect the sales of products and reduce corporate benefits.

[0008] 2) Polyurethane foam board has problems such as large internal heat generation and average high temperature resistance, and its resistance to moisture and heat is even worse. When the polyurethane foam board encounters high temperature, it is prone to secondary foaming, deformation, bulging and other phenomena, which will cause the panel to deform and be damaged, and lose its original thermal insulation effect.

[0009] 3) Currently, the highest fire protection grade of polyurethane can only reach Class B, while European countries generally require Class A fire protection grades for air conditioning panels. Therefore, polyurethane foam panels cannot meet the needs of European projects well, and thus cannot achieve the effect of increasing efficiency for enterprises.

[0010] 4) Although rock wool has better thermal insulation performance than polyurethane, it has almost no stickiness. Over time, under the action of gravity, rock wool will gradually slide downward, forming airspace above the panel, which will significantly affect the thermal insulation performance of the unit. In order to solve this problem, during the production process of the panel, it is necessary to use a hard connection method to fix the rock wool to improve the strength of the panel, but this structure will bring another problem that affects the thermal insulation effect of the panel, that is, the panel is prone to cold bridge effect.

[0047] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0048] The most critical concept of the utility model is that the inner and outer panels are respectively covered on the outside of the rectangular frame formed by the first profile to form a hollow panel structure, which can avoid the cold bridge effect caused by the direct contact between the inner and outer panels; and the second profile is arranged in the panel structure, which can not only effectively support the inner and outer panels to improve the overall strength, but also support the rock wool to avoid the rock wool from sliding and deforming and affecting the thermal insulation performance of the panel.

[0049] Please refer to Figures 1 to 7 The utility model provides a new type of anti-cold bridge rock wool composite board for various dehumidifiers, including a first profile 1, a second profile 2, an inner plate 3, an outer plate 4 and rock wool 5;

[0050] A plurality of first profiles 1 are connected end to end to form a rectangular frame;

[0051] The inner plate 3 and the outer plate 4 are respectively covered at both ends of the rectangular frame in the thickness direction to form an internal hollow panel structure;

[0052] The second profile 2 is arranged in the panel structure and separates the panel structure to form a storage space;

[0053] The rock wool 5 is arranged in the storage space.

[0054] Furthermore, the rock wool 5 is vertical wire rock wool.

[0055] Furthermore, the number of the first profiles 1 is four, and the first profiles 1 are connected end to end to form a rectangular frame.

[0056] Specifically, the first profile 1 and the second profile 2 are both partition materials with a thermal conductivity less than or equal to 0.17W / m·K, such as PVC. The thermal conductivity of this type of material is much smaller than that of metal parts, thereby providing structural support for the subsequent panels to effectively isolate the cold bridge effect; and the rock wool 5 used in the present application is vertical fiber rock wool. Compared with ordinary horizontal fiber rock wool, the vertical fiber rock wool fibers are finer, the uniformity between fibers is higher, the density is higher, and the thermal conductivity is lower, so it is not only superior to the horizontal fiber rock wool in terms of thermal insulation and sound absorption effects; at the same time, in the subsequent process of bonding the rock wool 5, the glue can better penetrate into the interior of the vertical fiber rock wool to enhance the bonding strength, instead of only allowing the glue to bond to the surface like the horizontal fiber rock wool, resulting in reduced bonding strength and then slipping.

[0057] From the above description, it can be seen that the beneficial effects of the utility model are: providing a new type of anti-cold bridge rock wool composite panel dedicated to a variety of dehumidifiers, by respectively covering the inner and outer panels 4 at the two ends in the thickness direction of the rectangular frame formed by the first profile 1 to form a hollow panel structure, the cold bridge effect caused by the direct contact between the inner and outer panels 4 can be avoided; and the second profile 2 is arranged inside the panel structure, which can not only effectively support the inner panel 3 and the outer panel 4 to enhance the overall strength, but also play a supporting role for the rock wool 5; compared with the existing air-conditioning panel, the design of using polyurethane as the thermal insulation structure is cancelled, and the problem of affecting the thermal insulation performance of the panel due to the sliding and deformation of the rock wool 5 is solved, so that the panel can ensure the thermal insulation effect while also complying with the design concept of green environmental protection, energy saving and high efficiency.

[0058] Furthermore, the first profile 1 includes a first component 11, a second component 12 and a third component 13 which are connected in sequence and form a U-shaped groove structure;

[0059] The notch of the first profile 1 is arranged toward the inside of the panel structure.

[0060] Specifically, the first component 11 is a U-shaped groove structure formed by the first component 11, the second component 12 and the third component 13; barbs are provided on the inner side wall of the first component 11 away from the second component 12 and on the inner side wall of the third component 13 away from the second component 12, and the barbs are arranged toward the second component 12, so that the rock wool 5 can be better clamped inside the first profile 1, thereby achieving an anti-falling effect.

[0061] From the above description, it can be seen that the first profile 1 and the second profile 2, whose grooves are both arranged toward the interior of the panel structure, can play a limiting role for the rock wool 5 placed inside the panel structure, thereby improving the stability of the rock wool 5 without adding additional fastening devices, thereby avoiding the rock wool 5 from slipping and deforming during use.

[0062] Furthermore, an air leakage prevention component 14 is provided on a side of the second component 12 facing away from the first component 11 .

[0063] Specifically, after the inner panel 3 and the outer panel 4 complete the covering work on the rectangular frame formed by the first profile 1, the first profile 1 only exposes the anti-air leakage component 14, thereby ensuring the airtightness of the formed panel structure and further providing protection for the thermal insulation performance of the panel structure.

[0064] Further, the air leakage prevention assembly 14 includes at least two air blocking strips 141;

[0065] The extension direction of the wind blocking strip 141 is parallel to the length direction of the second component 12;

[0066] The wind blocking strip 141 is disposed toward a side facing away from the first component 11 .

[0067] Furthermore, a limiting protrusion 15 is provided on the side of the second component 12 facing away from the first component 11;

[0068] The limiting protrusion 15 is arranged at a right angle to the second component 12 .

[0069] From the above description, it can be seen that after the first profile 1 forms a rectangular frame, a circle of limiting structures composed of limiting protrusions 15 will naturally be formed on the periphery of the rectangular frame; when the air-conditioning insulation panel is subsequently constructed, the limiting protrusions 15 can provide structural support for the positioning and fixing work between the panels; and when the panel is constructed, there is usually a gap between the limiting protrusions 15 and the second component 12, so an anti-leakage component 14 with multiple wind-blocking strips 141 is arranged on the second component 12, which can not only effectively improve the air tightness between adjacent panels, but also indirectly increase the friction between the panels, thereby avoiding the decomposition of the panels during use, thereby affecting the insulation effect.

[0070] Furthermore, the limiting protrusion 15 is a hollow structure.

[0071] Specifically, a hollow structure is also provided between the air leakage prevention component 14 and the second component 12, so as to reduce the cost and facilitate the production and processing of the manufacturer.

[0072] From the above description, it can be seen that designing the limiting protrusion 15 as a hollow structure can not only effectively reduce the overall weight of the panel and reduce production costs, but also reduce the thermal conductivity here, thereby further avoiding the cold bridge effect; and during the panel processing, the hollow structure can also effectively reduce the processing difficulty.

[0073] Furthermore, a mounting positioning groove 6 is provided on a side of the second component 12 facing away from the first component 11;

[0074] The slot direction of the installation positioning slot 6 is perpendicular to the opening direction of the first profile 1 .

[0075] Specifically, the notch of the installation positioning groove 6 is arranged in a direction away from the first component 11 .

[0076] From the above description, it can be seen that the installation positioning groove 6 can not only further reduce the weight of the panel to reduce costs, but also when fixing adjacent panels, the screws can directly penetrate the bottom of the installation positioning groove 6 and fix them to other panels, and the screws can also be hidden inside the installation positioning groove 6, thereby ensuring the aesthetics of the panel after installation.

[0077] Further, the second profile 2 is a groove-shaped structure;

[0078] The notch of the second profile 2 is arranged toward the inside of the panel structure;

[0079] A reinforcing member 21 matching the groove shape of the second profile 2 is disposed inside.

[0080] Specifically, the reinforcement 21 is any structure that can improve the overall rigidity strength, such as a reinforcing rib, or a channel steel built into the second profile 2, and the groove of the second profile 2 is provided with a limiter extending into the groove to prevent the reinforcement 21 from separating from the second profile 2, thereby reducing the strength of the panel structure.

[0081] From the above description, it can be seen that the second profile 2 with a groove structure provides structural support for the embedded reinforcement 21, and the reinforcement 21 arranged inside the second profile 2 can effectively improve the deformation resistance of the second profile 2, thereby indirectly improving the strength of the panel.

[0082] Furthermore, a side of the inner plate 3 located inside the panel structure and a side of the outer plate 4 located inside the panel structure are both provided with an adhesive layer;

[0083] The rock wool 5 is disposed between the inner plate 3 and the outer plate 4 and connected to the inner plate 3 and the outer plate 4 via an adhesive layer.

[0084] Specifically, the bonding layer is a sticky substance composed of AB glue. In addition to the high bonding strength, high hardness, high chemical resistance and other properties of general epoxy resin, the bonding agent also has an anti-yellowing effect, that is, after A and B are mixed, they will be completely dry in 5 minutes under an environment of 25 degrees. The higher the temperature, the shorter the drying time. It can bond plastic to plastic, plastic to metal, and metal to metal. After bonding, peeling requires a knife or hot melt separation. Therefore, the bonding effect between the rock wool 5 and the internal and external panels 4 can be continuously guaranteed without external force damage. At the same time, because the internal and external panels 4 always press the rock wool 5 tightly, the stability of the rock wool 5 can be better improved to prevent the rock wool 5 from sliding in the panel structure.

[0085] From the above description, it can be seen that this design can further improve the stability of the rock wool 5 in the panel structure. By matching the support of the second profile 2 with the bonding connection form, the problem that the rock wool 5 is easy to slip, thereby affecting the thermal insulation performance of the panel, can be better solved.

[0086] The novel anti-cold bridge rock wool composite board specially used for various dehumidifiers of the utility model can be used for heat preservation work of air-conditioning units.

[0087] Please refer to Figures 1 to 7 , Embodiment 1 of the present utility model is:

[0090] The working principle of the utility model is as follows: first, the first profile 1 is preliminarily formed into a rectangular structure by connecting the ends; then, the second profile 2 is staggered and connected, and after the reinforcement 21 is embedded in the interior of the second profile 2, the second profile 2 is fixed in the rectangular structure formed by the first profile 1; then, the rock wool 5 is preliminarily clamped in the frame structure surrounded by the first profile 1 and the second profile 2, and AB glue is evenly applied to the parts of the inner plate 3 and the outer plate 4 that need to contact the rock wool 5; finally, the inner plate 3 and the outer plate 4 with glue are bonded to the two ends of the rock wool 5 in the thickness direction, and the frame structure formed by the first profile 1 is completely wrapped around the inner plate 3 and the outer plate 4, thereby completing the insulation panel manufacturing process.

[0091] To sum up, the utility model provides a new type of anti-cold bridge rock wool composite panel specially used for various dehumidifiers. By respectively covering the inner and outer panels at the two ends in the thickness direction of the rectangular frame formed by the first profile to form a hollow panel structure, the cold bridge effect caused by the direct contact between the inner and outer panels can be avoided; and the second profile is arranged inside the panel structure, which can not only effectively support the inner and outer panels to improve the overall strength, but also support the rock wool; compared with the existing air-conditioning panel, the design of using polyurethane as the thermal insulation structure is cancelled, and the problem of affecting the thermal insulation performance of the panel due to the sliding and deformation of rock wool is solved, so that the panel can ensure the thermal insulation effect while also complying with the design concept of green environmental protection, energy saving and high efficiency, and after the inner and outer panels complete the covering work of the rectangular frame formed by the first profile, the first profile only exposes the air leakage structure, thereby effectively improving the airtightness of the panel structure, and then providing guarantee for the thermal insulation performance of the panel structure.
