Description
Technical Field
[0001] The utility model relates to the technical field of electric heating tubes, in particular to an explosion-proof PTC electric heating tube for commercial air conditioners. Background Art
[0002] Commercial air conditioners are composed of one or more cold and heat source systems and multiple air conditioning systems. The principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air conditioning system to offset the cooling load of the indoor environment. The heating system provides the required heat for the air conditioning system to offset the heat load of the indoor environment. Most commercial air conditioners are bidirectional, that is, they can both cool and heat. However, due to the limitations of the heating cycle itself, the working efficiency during heating is not as high as that during cooling, especially in cold areas. Therefore, auxiliary electric heaters are often required. PTC electric heaters have the characteristics of high heat exchange efficiency and good safety, and are widely used in air conditioners. There are two ways to install electric heaters in air conditioners: vertical installation and horizontal installation.
[0003] When some existing air-conditioning indoor units are cooling, condensed water is easy to accumulate on the surface of the heat sink of the electric heater. The condensed water is not collected and discharged, so the condensed water on the electric heater will accumulate at the bottom of the electric heater on the fixing device. In this way, when the air-conditioning indoor unit is running, the electric heater will pose a safety hazard. At the same time, if the air conditioner is not turned on for a long time, the surface of the heat sink will easily oxidize and form oxide scale.
[0004] Therefore, it is necessary to invent an explosion-proof PTC electric heating tube for commercial air conditioning to solve the above problems. Utility Model Content

[0026] The utility model is provided with a movable adjustment component, through which the heat sink 4 can be rotated under force, so that the heat sink 4 is in an inclined state, and the condensed water generated by the air-conditioning indoor unit during refrigeration can be moved along the upper surface of the heat sink 4, thereby avoiding accumulation of water on the heat sink 4 and causing the surface of the heat sink 4 to oxidize and form oxide scale. At the same time, the movement of the telescopic end of the electric push rod 5 can increase the inclination angle of the heat sink 4, thereby accelerating the flow of condensed water, which helps to discharge the condensed water generated by the air-conditioning indoor unit during refrigeration.
[0027] A collecting assembly is provided on one side of the first PTC electric heating tube holder 1, and the collecting assembly includes a collecting box 9, which is fixedly connected to the first PTC electric heating tube holder 1.
