Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner boxes, and mainly relates to an air conditioner box for low-temperature anti-condensation, easy and quick disassembly and assembly. Background Technique

[0002] Under the condition of low-temperature air supply of the air conditioner box, the external environmental temperature where the air conditioner box is installed is basically above 25°C, resulting in a large temperature difference between the inside and the outside of the box. If the cold bridge breaking effect of the box is not good, the low temperature inside is transmitted to the outer surface of the box. When the surface temperature is lower than the environmental dew point temperature, condensation will occur on the surface of the unit. If the box leaks air, the ambient air in the negative pressure section enters the low-temperature environment of the box, and condensation will occur on the inner surface of the box. The cold air flow inside the positive pressure section leaks to the outside of the box, directly leading to low-temperature condensation on the outer surface of the box. The condensation inside and outside the box directly affects the internal and external environments of the unit, causing corrosion of the box or internal and external components, thereby reducing the strength and sealing performance of the box and causing energy loss. How to improve the thermal resistance of the box and reduce air leakage has become the primary problem to be faced in development.

[0003] For the air conditioner box, the design of easy and quick disassembly is also crucial. When repairing, replacing parts or cleaning, being able to quickly disassemble the box can greatly improve work efficiency and reduce downtime. While solving the problems of large temperature difference heat transfer and sealing, the utility model continues to retain the convenient disassembly and assembly performance of the conventional air conditioner box, which has become the main purpose of development. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and to provide an air conditioner box for low-temperature anti-condensation, easy and quick disassembly and assembly. The combination design of the skeleton and the heat preservation panel for cold bridge breaking, supplemented by the line and surface sealing screw locking process, solves the heat preservation and sealing performance of the low-temperature air supply unit box body, and at the same time maintains the modular design of the air conditioner unit and the industrialization requirement characteristics of quick disassembly and assembly.

[0005] The purpose of the utility model is completed by the following technical solutions. An air conditioner box for low-temperature anti-condensation, easy and quick disassembly and assembly, includes a skeleton, a panel, a middle column and a tee joint. The connection parts between the panels are assembled into a box body structure by using the middle column, the skeleton or the tee joint; among them, the skeleton includes an outer aluminum bone, a heat-insulating plastic A and an inner aluminum bone. The cross-section of the outer aluminum bone is L-shaped, and the cross-section of the inner aluminum bone is square. The two sides of the outer aluminum bone and the two sides of the inner aluminum bone are respectively connected and integrally formed through the heat-insulating plastic A, and a heat-insulating cavity is formed between the two sides of the outer aluminum bone, the two sides of the inner aluminum bone and the heat-insulating plastic A.

[0006] Furthermore, the panel adopts a sandwich structure, including steel plate A, steel plate B and plastic edging. The two sides of steel plate A and steel plate B are provided with stepped plastic edging. Steel plate A and steel plate B are clamped into the plastic edging, and high-density polyurethane foam is injected into the space formed by steel plate A, steel plate B and plastic edging; the sealing screw passes through the plastic edging and is fixedly connected with the inner aluminum skeleton.

[0007] Furthermore, the middle column includes a square pipe and heat-insulating plastic B, and is installed in the space formed between two stepped plastic edgings. The sealing screw passes through the plastic edging and is fixedly connected with the middle column.

[0008] Furthermore, the tee joint includes connector A, connector B and connector C. The cross-section of connector A is square. Connector A, connector B and connector C form a connection assembly.

When the temperature difference between the inside and outside of the box body is 40 degrees, there is no condensation on the surface. It is an air-conditioning box body with high temperature difference resistance.

[0012] 2. The utility model includes a skeleton, a panel, a middle column and a tee joint. The skeleton adopts a combined structure of outer aluminum skeleton, heat-insulating plastic A and inner aluminum skeleton. The heat-insulating plastic A is stepped. When the skeleton is combined with the panel, a part of the skeleton and the plastic edging are joined together to form a structure with an approximately square cross-section; when the middle column is combined with the panel, a space for accommodating the middle column is just formed between two stepped plastic edgings; the panel of the box body is segmented and strengthened by the middle column, so that the combination of the box body can be mass-produced conveniently in a modular form.

[0013] 3. The tee joint structure is newly designed and is made of reinforced nylon with internal steel wires injection molded. It can connect the aluminum alloy skeletons in the three directions of length, width and height to form a box body frame, improve the forming efficiency of the box body and avoid the generation of corner gaps.

[0026] As Figure 5 shown, the skeleton 1 includes an outer aluminum bone 1-1, a heat-insulating plastic A 1-2, and an inner aluminum bone 1-3. The cross-section of the outer aluminum bone 1-1 is L-shaped, and the cross-section of the inner aluminum bone 1-3 is square. The two sides of the outer aluminum bone 1-1 and the two sides of the inner aluminum bone 1-3 are respectively connected and integrally formed through the heat-insulating plastic A 1-2, and a heat-insulating cavity 1-4 is formed between the two sides of the outer aluminum bone 1-1, the two sides of the inner aluminum bone 1-3, and the heat-insulating plastic A 1-2.

The surface of the aluminum alloy profile is subjected to anodizing treatment, hardened into a film and corrosion-resistant, and integrally formed with the heat-insulating plastic to achieve the purpose of high strength and high thermal resistance.

[0027] As Figure 6 shown, the panel 2 adopts a sandwich structure, including a steel plate A 2-2, a steel plate B 2-4, and a plastic edging 2-1. Stepped plastic edgings 2-1 are provided on both sides of the steel plate A 2-2 and the steel plate B 2-4. The steel plate A 2-2 and the steel plate B 2-4 are clamped into the plastic edging 2-1, and high-density polyurethane foam 2-3 is injected into the space formed by the steel plate A 2-2, the steel plate B 2-4, and the plastic edging 2-1 to form a 100-mm thick insulation layer; the sealing screw 5 passes through the plastic edging 2-1 and is fixedly connected to the inner aluminum bone 1-3.

[0030] The low-temperature anti-condensation and easy-disassembly and assembly type air-conditioning box of the present utility model is used for producing, filtering, and conveying low-temperature air. It is widely used in low-temperature environment industries. For example, in the food processing industry, the refrigeration temperature needs to be controlled at 0°C to 8°C, and the relative humidity is maintained at 75% to 85%, which can ensure the freshness and taste of food; the freezing temperature needs to be controlled at -24°C to -18°C, and the relative humidity is maintained at 85% to 95%, which can effectively control the growth of microorganisms and cell activities in frozen food and maintain the quality and safety of food. The cold drying of biological medicinal materials also needs to control the temperature at about -20°C to -10°C. Under the demand for large-area air supply, in the normal temperature area of the low-temperature air supply unit, the temperature difference between the inside and outside of the box reaches 35 to 40°C. The low-temperature air supply demand puts forward higher requirements for the heat preservation performance and sealing performance of the box of the air supply unit.
