Description

Manufacturing Method of insulation panel with improved insulation performance and a refrigeration-container using it The present invention relates to a method for manufacturing a panel with improved thermal insulation performance and a refrigeration tower using the same. More specifically, the invention relates to an insulating panel that improves the thermal insulation effect by blocking the leakage of cold air or the inflow of outside air through the assembly and connection parts of the panel, and a refrigeration tower using the insulating panel. Generally, when transporting and temporarily storing various food products such as milk, dairy products, frozen desserts, meat, seafood, and vegetables, special vehicles equipped with so-called refrigerated trucks with refrigeration capabilities are used to prevent quality degradation, such as improving hygiene, preventing spoilage, and maintaining freshness. When constructing a refrigeration tower, individual spaces are partitioned using walls assembled by connecting flat insulation panels in horizontal or vertical directions. These insulation panels are generally installed by inserting insulation material into the outer frame, and since they are installed in addition to existing walls, floors, and ceilings, they must be securely fixed, and they must be constructed so that insulation is provided at the installation site to prevent condensation or freezing caused by the temperature difference of the refrigeration tower. However, when constructing a refrigeration tower, since multiple flat insulation panels are connected to form curved parts such as the rear door, door, or wheel guard of the refrigeration tower, there was a problem in that cold air inside the refrigeration tower leaked out or outside air was drawn in due to gaps between the connected insulation panels, thereby degrading the refrigeration performance inside the refrigeration tower. In addition, since each insulation panel is connected by a connecting member, there is also a problem where internal cold air leaks through the gaps in the connecting member penetrating the insulation panel, thereby degrading the insulation performance. As an example of solving this problem, Korean Registered Utility Model Publication No. 20-0202508 (August 30, 2000) discloses a structure for an insulation assembly for a refrigerated truck that can increase the insulation efficiency inside the refrigerated truck by using materials such as lightweight insulation materials, aluminum sheets, and plywood to improve the insulation performance of the refrigerated truck. However, even in this case, the problem of internal cold air leakage occurring when connecting insulation assemblies to curved sections still exists. If, in order to solve these problems, a method for manufacturing panels with improved thermal insulation performance and a refrigeration tower using the same are provided, By manufacturing insulation panels into curved shapes using vacuum forming and attaching and laminating insulation materials to match the desired shape, or by spraying and laminating insulation foam, it will be possible to prevent cold air leakage from inside the refrigeration tower and the inflow of outside air during panel assembly, thereby enhancing insulation performance. In addition, the inventor arrived at the present invention by noting the possibility that the insulation performance could be improved by providing an additional guide bushing to the connecting member for connecting the insulation panels to prevent cold air from leaking through the gap of the connecting member.
