Furthermore, the hydraulic rods can be adjusted to accommodate different thicknesses of plywood, reducing the risk of high-temperature contact, thus combining practicality and safety.

Description

Technical Field

[0001] This utility model relates to the field of plywood heat dissipation technology, specifically a plywood layered heat dissipation device. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneers glued perpendicular to each other. Plywood is one of the commonly used materials for furniture and one of the three major types of engineered wood products. After processing, plywood needs to be placed on a heat dissipation rack for heat dissipation.

[0003] However, existing plywood cooling racks have significant shortcomings. When in use, the plywood is placed directly on the rack's placement board, and heat dissipation mainly relies on the convection air generated by the fan. However, in this method, the bottom of the plywood is completely blocked by the placement board, preventing it from fully contacting the air. This results in uneven heat dissipation rates between the upper and lower surfaces, with the upper surface cooling faster and the lower surface cooling slower, affecting the overall heat dissipation efficiency. Furthermore, the temperature difference between the upper and lower surfaces causes the wood fibers to expand and contract at different rates. The upper surface contracts rapidly due to cooling, while the lower surface remains relatively expanded due to its higher temperature. This uneven deformation can cause the plywood to bend and warp, and in severe cases, irreversible deformation may occur, rendering it unusable. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a plywood layered heat dissipation device is provided, comprising: a frame, two pairs of mounting rods are fixedly connected between the top and bottom of the frame, a plurality of lower cooling plates are fixedly installed between the inner walls of opposite sides of the two pairs of mounting rods, and an upper cooling plate is provided above each of the lower cooling plates; connecting rods are fixedly connected at the four corners of the plurality of upper cooling plates, the connecting rods respectively penetrate the upper cooling plates, a top plate is fixedly installed between the top ends of the four connecting rods, a hydraulic rod is fixedly installed on the top of the frame, and the output end of the bottom of the hydraulic rod is connected to the top of the top plate.

[0006] Furthermore, both the lower cooling plate and the upper cooling plate have cooling chambers inside.

[0012] The advantages of this invention are that after hot pressing, the plywood is placed on the lower cooling plate, and the hydraulic rod drives the upper cooling plate to press down and fit together.

[0021] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 and Figure 2 The plywood layered heat dissipation device shown includes: a frame 1, two pairs of mounting rods 11 fixedly connected between the top and bottom of the frame 1, multiple lower cooling plates 12 fixedly installed between the inner walls of opposite sides of the two pairs of mounting rods 11, and upper cooling plates 13 provided above each of the lower cooling plates 12; connecting rods 14 fixedly connected at the four corners of the multiple upper cooling plates 13, the connecting rods 14 passing through the upper cooling plates 13 respectively, a top plate 15 fixedly installed between the top ends of the four connecting rods 14, and a hydraulic rod 16 fixedly installed on the top of the frame 1, the output end of the bottom of the hydraulic rod 16 being connected to the top of the top plate 15.

[0024] When the plywood is processed after hot pressing and then cooled, the plywood is placed on the lower cooling plate 12. Then, the hydraulic rod 16 is pushed out to move the top plate 15 downward. The connecting rod 14 drives the upper cooling plate 13 downward, so that the upper cooling plate 13 presses down on the top of the plywood. The upper cooling plate 13 and the lower cooling plate 12 absorb the heat generated by the plywood, so that the plywood can be cooled evenly. The brake casters at the bottom of the frame 1 can be moved easily. When it is moved to the desired position, the brake is stepped on to fix the casters and prevent the frame 1 from moving when the plywood is placed.

[0025] The frame 1 is equipped with a power supply and a power cord, which are connected to a power socket for power supply. The frame 1 is also equipped with a hydraulic system to control the extension and retraction of the hydraulic rod 16.

[0026] As attached Figure 3 , Figure 4 and Figure 5 As shown, both the lower cooling plate 12 and the upper cooling plate 13 have cooling chambers 2 inside. Each of the lower cooling plate 12 and the upper cooling plate 13 has a liquid outlet 21 on one side and a liquid inlet 22 on the other side. The liquid outlet 21 and the liquid inlet 22 are respectively connected to the cooling chambers 2. A coolant tank a3 is located on one side of the frame 1. A water pump 31 is fixedly installed on the top of the coolant tank a3. The input end of the water pump 31 is fixedly connected to a pumping pipe 32, and the output end of the water pump 31 is fixedly connected to... A delivery hose 33 is connected, and the bottom end of the extraction pipe 32 extends into the coolant tank a3. One end of the delivery hose 33 is connected to the inlet 22. A coolant tank b34 is provided on the other side of the frame 1. A return hose 35 is fixedly connected to the top of the coolant tank b34. One end of the return hose 35 is connected to the outlet 21. A transfer pipe 36 is connected between the back sides of the coolant tank a3 and the coolant tank b34. Cooling fans 37 are fixedly installed on the opposite sides of the coolant tank a3 and the coolant tank b34.

[0027] Coolant is injected through the filling ports at the top of coolant tanks a3 and b34. After the water pump 31 starts, the liquid inside coolant tank a3 is drawn out through the extraction pipe 32 and delivered to the inlet 22 through the delivery hose 33. The coolant enters the cooling chamber 2, and the heat generated by the plywood is directly transferred to the lower cooling plate 12 and the upper cooling plate 13. The coolant in the cooling chamber 2 carries away the heat from the lower cooling plate 12 and the upper cooling plate 13, thereby dissipating heat and cooling the plywood. The coolant that has carried away the heat exits from the outlet. The coolant is discharged from tank 21 and flows into coolant tank b34 through return hose 35. As the coolant absorbs heat and flows into coolant tank b34, the coolant level in coolant tank b34 rises and flows back to coolant tank a3 through transfer pipe 36 to form a circulation. Coolant tanks a3 and b34 are made of aluminum, and the heat of the coolant is directly dissipated to the outside. After the cooling fan 37 is turned on, the airflow on one side surface of coolant tanks a3 and b34 can be accelerated, thereby improving the cooling efficiency of the coolant and preventing the coolant from overheating.

[0028] In a preferred embodiment, both coolant tank a3 and coolant tank b34 are provided with filling ports 4 at the top, and each filling port 4 is threaded with a sealing cap 41. Both coolant tank a3 and coolant tank b34 are provided with drain pipes 42 near the bottom on the front side, and each drain pipe 42 is provided with a valve 43.

[0029] Furthermore, coolant can be added to coolant tanks a3 and b34 through filling port 4, and coolant can be discharged through drain pipe 42. Coolant is discharged after opening valve 43, and coolant is prevented from flowing out after valve 43 is closed.

[0030] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control functions, and the existing publicly available power connection technologies are not described in detail in the text.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
