Description

Technical Field

[0001] The utility model belongs to the technical field of air curtain machines, and particularly relates to a high-efficiency air curtain machine. Background Technique

[0002] An air curtain machine is an air purification device that blows out the high-temperature heat generated on the surface of a heater (the heater is composed of several PTC ceramic chips) through a powerful air flow generated by a high-speed motor driving a cross-flow or centrifugal air wheel to form a heat-containing curtain of air, and is widely used in places such as shopping malls, supermarkets, hotels, restaurants, warehouses, factories, and logistics centers to create a more comfortable and healthy environment for people's life and work.

[0003] At present, there are various styles of air curtain machines on the market, and generally, they adopt a structure in which multiple circles of fins are arranged axially on the outer surface of the heating pipe, and the fins wound around the heating pipe are used to increase its contact area with the surrounding environment, so that heat can be transferred to the air more quickly.

[0004] However, in the actual use process, the above structure is prone to the following problems: 1. During its heat dissipation process, it needs to first transfer the heat of the heat medium in the heating pipe to the surface of the heating pipe, then transfer the heat from the surface of the heating pipe to the fins, and finally transfer the heat from the fins to the air. Therefore, its entire heat conduction path is relatively long, and there is an easy problem of energy loss. Content of the Utility Model

[0005] The technical problem solved by the utility model is to provide a high-efficiency air curtain machine that can effectively shorten the heat conduction path and make full use of the energy contained in the heat source, and has the advantages of high energy utilization efficiency, energy conservation and environmental protection.

[0006] To solve the above technical problems, the technical solution provided by the present utility model is as follows: A high-efficiency hot air curtain machine, which includes a machine shell. An air inlet is provided at the top or side wall of the machine shell, and an air inlet fan is installed at the air inlet; an air outlet is provided at the bottom of the machine shell; a heating component is installed in the inner cavity of the machine shell at a position between the air outlet and the air inlet. The heating component includes a lower heating box installed at the inner bottom of the machine shell and an upper heating box installed at the inner top of the machine shell. At least two inclined finned tubes are arranged in parallel along the length direction between the top surface of the lower heating box and the bottom surface of the upper heating box. The inner cavity of the inclined finned tube is communicated with the inner cavities of the upper heating box and the lower heating box, and the inner cavities of the inclined finned tube, the upper heating box and the lower heating box are filled with a superconducting liquid; an electric heating tube is installed in the inner cavity of the lower heating box, and the end of the electric heating tube extends out of the machine shell and is connected with a power supply component. At this time, since the present utility model directly pours the superconducting liquid into the inclined finned tube, during its heat dissipation process, it can directly transfer the heat of the superconducting liquid in the heating tube to the surface of the inclined finned tube, and then transfer the heat from the inclined finned tube to the air, thereby effectively shortening the entire heat conduction path, reducing heat loss, making full use of the energy contained in the heat source, and further improving the heat conduction efficiency of the entire hot air curtain machine. At the same time, compared with the traditional fin structure, the inclined finned tube structure of the present utility model also has the beneficial effect of being convenient for cleaning.

[0007] Further, two layers of filter nets are arranged between the lower heating box and the upper heating box. The inclined finned tube is located between the two layers of filter nets, and the air passing through the inclined finned tube is filtered by the filter nets to prevent floating dust from accumulating on the surface of the inclined finned tube.

[0008] Further, a filter cover is provided outside the air inlet fan, and the air entering the air inlet fan is filtered by the filter cover to effectively reduce the impurities entering the machine shell.

[0009] Further, a liquid filling port is provided on the upper heating box, and liquid filling treatment is carried out through the liquid filling port.

[0010] Further, an exhaust port is provided on the upper heating box, and an exhaust valve is installed on the exhaust port, and exhaust treatment is carried out through the exhaust valve at the exhaust port.

[0011] Further, a left support frame is connected between the left ends of the upper heating box and the lower heating box, and a right support frame is connected between the right ends of the upper heating box and the lower heating box. Each of the left support frame and the right support frame is provided with a vertical linear module. A horizontal connecting plate is connected between the power output ends of the two vertical linear modules. The horizontal connecting plate is located outside the filter net on the air inlet side of the inclined finned tube. A horizontal linear module is installed on the horizontal connecting plate. A horizontal sliding plate is installed at the power output end of the horizontal linear module. A dust suction nozzle is arranged on the side of the horizontal sliding plate facing the filter net. A cleaning brush is arranged inside the dust suction nozzle. The air outlet end of the dust suction nozzle is connected to a dust suction machine through a dust suction hose. The dust suction machine is installed on the side of the horizontal sliding plate or the horizontal connecting plate away from the filter net. After the present utility model is used for a period of time, the cleaning brush can be controlled to move horizontally and vertically by controlling the vertical linear module and the horizontal linear module to move in corresponding directions, so as to clean the filter net. Moreover, the dust and the like generated during the cleaning process can be directly sucked into the dust suction machine through the dust suction nozzle, avoiding secondary pollution to the inner wall of the machine shell.

[0012] As can be seen from the above technical solutions, the present utility model has the following advantages: 1. Since the superconducting liquid is directly poured into the inclined finned tube of the present utility model, during its heat dissipation process, it can directly transfer the heat of the superconducting liquid in the heating tube to the surface of the inclined finned tube, and then transfer the heat from the inclined finned tube to the air, thereby effectively shortening the entire heat conduction path, reducing heat loss, making full use of the energy contained in the heat source, and further improving the heat conduction efficiency of the entire hot air curtain machine; 2. After the present utility model is used for a period of time, the cleaning brush can be controlled to move horizontally and vertically by controlling the vertical linear module and the horizontal linear module to move in corresponding directions, so as to clean the filter net and ensure that the air can pass smoothly; moreover, the dust and the like generated during the entire cleaning process can be directly sucked into the dust suction machine through the dust suction nozzle, avoiding secondary pollution to the inner wall of the machine shell.
