Description

Technical Field

[0001] The utility model specifically relates to a composite aluminum foil heater with a PE film. Background Art

[0002] An electric heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, has high heating power, and is widely used. An aluminum foil heater is a heating device that uses aluminum foil as a heating element. This type of heater usually uses aluminum foil as a heating film.

[0003] The existing aluminum foil heaters have a relatively fixed shape after production. In actual use, due to the different shapes of the devices to be heated, the aluminum foil heater cannot make good contact with them, and the thermal conductivity is poor. In addition, the heating power of the aluminum foil heater is usually small. In the case of poor thermal conductivity, it is difficult to complete the heating of the predetermined position and device, which affects the scope of application. For this reason, we propose a composite aluminum foil heater with PE film. Utility Model Content

[0010] Preferably, a reserved groove is formed on the outer surface of the silicone rubber layer, and the reserved groove is evenly distributed at multiple locations along the length direction of the silicone rubber layer.

[0011] Preferably, the outer diameter of the silicone rubber layer is 0.2-1 mm.

[0012] Preferably, an adhesive layer is provided on the outer surface of the flexible heating component, and the aluminum foil layer and the flexible heating component are fixed via the adhesive layer.

[0014] Preferably, a plurality of folding lines are provided, and two ends of the folding lines are respectively aligned with the edges of the aluminum foil layer.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] By providing a flexible heating component, an aluminum strip and folding lines, the device can be quickly bent and shaped to avoid the heater being fixed in shape and not being well adapted to different occasions. The device is easy to adjust and can be bent arbitrarily according to actual needs to improve the good contact and heat conduction effect with the position to be used. The PE film and the reflective layer can be well waterproof and insulated. When the aluminum foil layer is broken, it can attract the attention of others, thereby increasing the convenience of later maintenance and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a composite aluminum foil heater with a PE film, comprising:

[0023] Aluminum foil layer 1, a flexible heating component 4 is arranged inside the aluminum foil layer 1, which is convenient for bending at any position, so that the aluminum foil layer 1 can better contact with the position to be heated according to the actual use position, and the two ends of the flexible heating component 4 are provided with connecting terminals 3;

[0024] The aluminum strip 5 is fixed to the inner edge of the aluminum foil layer 1 for shaping during folding, so as to better maintain the shape of the aluminum foil layer 1 after folding;

[0025] The folding line 2 is arranged on the front surface of the aluminum foil layer 1 to facilitate better folding and bending operations.

[0026] In this embodiment, preferably, the flexible heating component 4 includes a heating wire 41, a silicone rubber layer 42, a PE film 43 and a reflective layer 44. The heating wire 41 is arranged on the inner side of the silicone rubber layer 42. The material of the heating wire 41 is preferably nickel-chromium alloy or iron-chromium-aluminum alloy. The outer surface of the silicone rubber layer 42 is provided with a protective PE film 43. The outer surface of the PE film 43 has a reflective layer 44, which is convenient for better waterproofing and insulation effects. After the aluminum foil layer 1 is broken, it can well attract the attention of others through the reflective layer 44, which is convenient for maintenance and repair.

[0027] In this embodiment, preferably, a reserved groove 45 is opened on the outer surface of the silicone rubber layer 42, and the reserved grooves 45 are evenly distributed in multiple locations along the length direction of the silicone rubber layer 42 to facilitate better bending.

[0028] In this embodiment, preferably, the outer diameter of the silicone rubber layer 42 is 0.2-1 mm.

[0029] In this embodiment, preferably, an adhesive layer 7 is provided on the outer surface of the flexible heating component 4, and the aluminum foil layer 1 and the flexible heating component 4 are fixed by the adhesive layer 7, which facilitates connection and fixation.

[0030] In this embodiment, preferably, Velcro 6 is provided on the front and rear surfaces of the aluminum foil layer 1. The Velcro 6 is rectangular, so as to better connect and fix the adjacent edges of the aluminum foil layer 1 after bending and folding.

[0031] In this embodiment, preferably, a plurality of folding lines 2 are provided, and both ends of the folding lines 2 are respectively aligned with the edges of the aluminum foil layer 1 to facilitate better folding convenience.

[0032] The working principle and use process of the utility model are as follows: when in use, the edge of the aluminum foil layer 1 can be bent at any position through the aluminum strip 5, so that the aluminum foil layer 1 can better contact the object to be heated, and further after bending, the stability of the bent position can be further maintained through the cooperation of any two Velcro strips 6. During the bending process, the silicone rubber layer 42 can be better deformed through the reserved groove 45 on the outer surface, and the heating wire 41 can be protected by the elastic energy of the silicone rubber layer 42, so that a smooth bend is formed at the bend, and the damage of the heating wire 41 caused by excessive bending angle is reduced. Furthermore, the PE film 43 can be well waterproof, provide certain insulation support, and ensure the insulation stability during heating. When the aluminum foil layer 1 is broken, the reflective layer 44 can well attract the attention of others, which is convenient for maintenance and replacement at a later time.
