Description

Technical Field

[0002] In the field of industrial dehumidification equipment, the design of the unit box structure has long faced the technical dilemma that strength and sealing cannot be achieved at the same time. The current mainstream air handling unit (AHU) boxes are mainly divided into two structural forms: framed and frameless, but both have significant defects:

[0003] (1) For the framed structure units, the following technical problems exist:

[0004] Structural problems: (1) Dependence on welded metal profile frames; (2) An average of 120 to 150 welding joints are required for a single unit; (3) The self-weight of the frame accounts for 35% to 40% of the total weight of the equipment.

[0005] Assembly defects: (1) The sealing plate needs to be drilled and tapped separately; (2) Welding thermal deformation results in out-of-tolerance flatness of the sealing surface; (3) On-site installation and adjustment take more than 60% of the total working hours.

[0006] (2) For the frameless structure units, the following technical problems exist:

[0007] Sealing failure problems: (1) The groove inlay fit gap significantly exceeds the EN1886 standard; (2) The air leakage rate generally exceeds the GB / T14294 limit value.

[0008] Reliability defects: (1) The connection loosening rate is high after 2000 hours of operation; (2) A large amount of condensate accumulates at the box splicing joints.

[0080] In some embodiments, the depth of each mounting groove is 1 mm to 1.5 mm.

[0081] The housing 2 of the present invention includes a sealing plate 21. Further, in order to improve the applicability of the dehumidification device, the housing 2 of the present invention may further include a connecting plate and a support frame.

Refer to Figure 5 .

[0099] In some embodiments, surface cooling components 62 are provided between the 1st to the (N - 1)th runner assemblies 11, and the heat exchange tubes of the surface cooling components 62 are inclined at an angle of 15° to 30° with respect to the partition 5 to enhance air flow disturbance and improve heat exchange efficiency.

[0100] In some embodiments, heating components 61 are provided between the 1st to the Nth runner assemblies 11, and the power density of the heating components 61 is distributed in a gradient along the air flow direction, for example: increasing or decreasing step by step. Preferably, the power density decreases step by step along the air flow direction to match the decreasing characteristic of the air moisture content and avoid overheating at the end.

[0101] It can be seen that the partition 5 of the present invention can not only accurately separate the treatment channel and the regeneration channel of the air duct 8 between adjacent runner assemblies 11 to prevent air flow interference, but also serve as a stable installation platform to carry the heating component 61 and the surface cooling component 62, greatly reducing the space occupied by the dehumidification equipment and achieving a balance between miniaturization and high performance. For example, a two-stage dehumidification device more than ten meters long can be reduced to 6 m to 8 m. Even in a cramped production workshop, the multi-stage dehumidification device of the present invention can be deployed to control the temperature and humidity of the workshop environment.

Herein, the preset area is the connection. Preferably, the fifth preset area is the periphery of the connecting plate.

[0106] In some embodiments, in order to disperse stress concentration, the corrugation direction of the corrugated sealing strip is perpendicular to the force direction of the connecting member; in order to elastically deform to compensate for installation errors and assembly clearances, the corrugation height of the corrugated sealing strip is set to be 3 mm to 5 mm; in order to reduce fatigue wear under dynamic conditions and extend the service life of the corrugated sealing strip, the corrugation direction of the corrugated sealing strip forms an angle of 75° to 90° with the axis of the connecting member; in order to ensure that the corrugated sealing strip still maintains a rebound rate of ≥90% after being compressed for a long time, the compression rate of the corrugated sealing strip is set to be 30% to 60% to adapt to the pre-tightening force of the fastening bolt of 20 N·m to 50 N·m.

[0107] In some embodiments, the corrugated sealing strip is made of foamed sponge, ternary foam or ethylene propylene diene monomer (EPDM) rubber. Further, the corrugated sealing strip is a three-layer composite structure, including, in sequence: a first layer, a second layer, and a third layer. Among them, the first layer is an EPDM rubber layer with a thickness of 0.2 mm to 0.5 mm, which can improve the aging resistance of the corrugated sealing strip; the second layer is a foamed silica gel buffer layer with a thickness of 2 mm to 4 mm, which not only has good flexibility to achieve thermal deformation compensation, effectively avoiding sealing failure caused by physical deformation, but also can absorb vibration energy, with the shock absorption effect increased by 60%, to ensure the stable and reliable operation of the dehumidification device; the third layer is a pressure-sensitive adhesive layer with a thickness of 0.1 mm to 0.3 mm, which can achieve zero-gap bonding.

[0108] In actual application, one side of the first adhesive layer of the present invention is bonded to the partition 5, and the other side of the first adhesive layer is bonded to the frame 112 of the runner assembly 11.

One side of the third adhesive layer is bonded to the heating assembly 61, and the other side of the third adhesive layer is bonded to the second side of the partition 5 opposite to the first side.

[0109] In addition, the adhesive layer is a sealing adhesive layer, and different types of adhesive layers can be selected according to different working conditions. For example: a silicone sealing adhesive layer, with a temperature resistance range of -60°C to 250°C, suitable for high and low temperature alternating environments.

[0110] In some embodiments, in order to balance the bonding strength and flexibility of the adhesive layer, the thickness of the adhesive layer is set to be 0.5 mm to 1.2 mm. In addition, in order to enhance the tear resistance of the adhesive layer, a fiberglass mesh cloth can be added to the surface of the adhesive layer, for example: 80 g / m 2 to 100 g / m 2 .
