Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to a compressor heating belt. Background Technology

[0002] Chinese Patent Publication No. CN204152781U, published on February 11, 2015, discloses an electric heating belt for an air conditioner compressor crankcase. It includes: a heating belt body containing a heating wire; a power cord, one end of which is electrically connected to the heating wire inside the heating belt body, and the other end connected to a power source; two clips, each located at one end of the heating belt body; and a tension spring, one end of which is connected to one of the clips, and when the heating belt body is wound around the compressor crankcase, the other end of the tension spring is engaged with the other clip. Similarly, Chinese Patent Publication No. CN209129822U, published on July 19, 2019, discloses a durable heating belt, including: a heating belt body, clips, a tension spring, and a temperature sensing unit. The heating belt body has a heating wire inside; two buckles are respectively located on the heating belt end caps at both ends of the heating belt body; the buckles are U-shaped, that is, the buckles include a base and a pair of symmetrically arranged wings connected to the base; the pair of wings are adapted to connect with the heating belt end caps; a gap is formed between the base and the heating belt end caps; a tension spring, when the heating belt body is wound around the compressor crankcase, the two ends of the tension spring are adapted to engage with the bases of the two buckles; the temperature sensing unit includes a terminal block connected to the power cord, a component box connected to the terminal block on one side, a thick wire on the other side of the component box, a thin wire connected to the terminal block, and a glass-sealed thermistor inside the heating belt body.

[0003] Both types of compressor heating belts use heating wires. The heating wires are not easy to position during installation. Therefore, the heating belts need to be processed by extrusion (the straightened heating wires are pulled out of the extrusion die, and the silicone rubber is extruded out of the extrusion die at the same time). Then, the appropriate length is cut as needed, and a portion of the silicone rubber is cut off from both ends of the cut heating belt to expose the heating wires, which are then connected to the lead wires. Further, another layer of silicone rubber is used to wrap the ends. The process is complicated.

[0004] In addition, the heating wire itself heats up slowly, and because it is narrow, it covers a very narrow area, resulting in poor heating effect.

[0005] Also, the heating wire should not be bent at a large angle, otherwise it will easily break. Utility Model Content

[0006] The purpose of this invention is to provide a compressor heating belt that has a reasonable structure, heats up quickly and evenly, is flexible, and will not break.

[0007] The purpose of this utility model is achieved as follows: A compressor heating belt includes a silicone rubber belt body with connecting portions at both ends. A nano heating film is disposed inside the silicone rubber belt body, and an lead wire is electrically connected to the nano heating film, with the lead wire extending out of the silicone rubber belt body.

[0008] The objective of this utility model can also be achieved by the following technical measures: As a more specific embodiment, the nano-heating film is elongated and comprises two pieces; each nano-heating film has electrodes at both ends, wherein the electrodes at one end of the two nano-heating films are connected in series via a conductive bridge, and the electrodes at the other ends of the two nano-heating films are electrically connected to the lead wires respectively. Alternatively, the nano-heating film is a single piece, elongated and comprised of electrodes at both ends, with the lead wires electrically connected to the electrodes.

[0009] As a further embodiment, the electrode extends along the width of the nano-heating film; two leads extend from the same end of the silicone rubber strip.

[0010] As a further embodiment, the nano-heating film is an electric heating film of polyimide, carbon nanotubes and graphene, with a thickness of 5 micrometers to 150 micrometers; the electrode is a conductive coating or a copper foil layer.

[0011] As a further embodiment, the silicone rubber strip includes a thin strip segment and thickened heads located at both ends of the thin strip segment, the nano-heating film is wrapped inside the thin strip segment, and both ends of the nano-heating film extend into the thickened heads.

[0012] As a further embodiment, the connecting part includes connecting ears and a tension spring. The connecting ears are provided in two and are respectively riveted to the thickened heads at both ends of the silicone rubber strip. The rivets used for riveting are separated from the nano heating film. The tension spring has hooks at both ends and the connecting ears have hanging holes for connecting with the hooks.

[0013] As a further embodiment, the lead wire extends from the thickened head end of one end of the silicone rubber tape. The thickened head has a wrapping head at the root of the exposed portion of the lead wire. The wrapping head is integrally formed with the thickened head and wraps around the root of the lead wire.

[0014] As a further improvement, the upper and lower sides of the thickened head transition smoothly with the upper and lower slopes of the thin strip segment. Therefore, the heating strip has a symmetrical structure front to back (upper to lower), making assembly easier.

[0015] As a further embodiment, the silicone rubber strip is composed of two halves; or, the thin strip segment of the silicone rubber strip and the nano heating film are co-extruded and formed, and the thickened heads at both ends are secondary processed and connected to the two ends of the thin strip segment.

[0016] The beneficial effects of this utility model are as follows: (1) The compressor heating belt uses a nano heating film for heating, which has a fast heating speed, a large heating area, and a more even temperature. The nano heating film has a certain toughness and plasticity, making the heating belt softer and able to be bent at an angle without breaking the internal heating element. It has a long service life and more flexible storage and transportation options.

[0017] (2) The nano heating film of this compressor heating belt is easy to lay flat. Therefore, the silicone rubber belt can be composed of two halves, with the nano heating film sandwiched in the middle for fixation, making the processing more convenient. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1, see Figures 1-5 As shown, a compressor heating belt includes a silicone rubber belt body 1, with connecting parts at both ends of the silicone rubber belt body 1. A nano heating film 2 is disposed inside the silicone rubber belt body 1, and an lead wire 3 is electrically connected to the nano heating film 2, with the lead wire 3 extending out of the silicone rubber belt body 1.

[0027] The nano-heating film 2 is elongated and consists of two pieces; each nano-heating film 2 has electrodes 21 at both ends, wherein the electrodes 21 at one end of the two nano-heating films 2 are connected in series through a conductive bridge 22, and the electrodes 21 at the other end of the two nano-heating films 2 are electrically connected to the lead wire 3 respectively.

[0028] The electrode 21 extends along the width of the nano-heating film 2; two lead wires 3 extend from the same end of the silicone rubber strip 1.

[0029] The nano-heating film 2 is an electric heating film of polyimide, carbon nanotubes and graphene, with a thickness of 5 micrometers to 150 micrometers; the electrode 21 is a conductive coating or a copper foil layer.

[0030] The silicone rubber strip 1 includes a thin strip segment 11 and thickened heads 12 located at both ends of the thin strip segment 11. The nano heating film 2 is wrapped inside the thin strip segment 11, and both ends of the nano heating film 2 extend into the thickened heads 12.

[0031] The connecting part includes connecting ears 4 and tension springs 5. Two connecting ears 4 are provided and riveted to the thickened heads 12 at both ends of the silicone rubber strip 1. Rivets 6 are used for riveting and are separated from the nano-heating film 2. Hooks 51 are provided at both ends of the tension springs 5, and hanging holes 41 are provided on the connecting ears 4 for connecting with the hooks 51. Specifically, the thickened heads 12 of the silicone rubber strip 1 have through holes 14 that avoid the lead wire 3. The rivets 6 pass through the through holes 14 and the connecting ears 4 before riveting.

[0032] The lead wire 3 extends from the thickened head 12 at one end of the silicone rubber tape 1. The thickened head 12 is provided with a wrapping head 13 at the root of the exposed part of the lead wire 3. The wrapping head 13 is integrally formed with the thickened head 12 and wraps the root of the lead wire 3.

[0033] The upper and lower sides of the thickened head 12 transition with the upper and lower sides of the thin strip 11.

[0034] The silicone rubber tape 1 is composed of upper and lower halves; wherein, after the lower half is formed, it is attached with such... Figure 3 The nano heating film 2 shown is then attached to the upper half that is not completely dried, and then pressed together to form a whole, so that the nano heating film 2 is tightly wrapped inside the silicone rubber tape 1.

[0035] Its working principle is as follows: The heating strip is wrapped around the outer circumference of the air conditioner compressor, especially around the crankshaft. The hooks 51 at both ends of the tension spring 5 are hooked onto the hanging holes 41 of the connecting lugs 4 at both ends of the heating strip, thus tightening the heating strip. When the two lead wires 3 are energized, the nano heating film 2 heats up, thereby ensuring that the compressor can operate in a low-temperature environment.
