Description

Technical Field

[0001] This utility model relates to the field of gas pipeline technology, specifically to an antifreeze and heat-insulating electric heating hose. Background Technology

[0002] The main function of the oil-gas separator outlet pipe assembly is to heat the oil vapor and unburned CO and other fuel gases separated by the oil-gas separator and send them to the turbocharger intake to mix with air. After being pressurized, the mixture enters the cylinder for secondary combustion. In cold northern regions, the low winter temperatures can easily cause the oil-gas separator outlet hose to freeze, blocking the outlet and leading to oil-gas separator malfunction, affecting engine reliability and emissions.

[0003] Therefore, this application proposes an electrically heated antifreeze hose, which consists of two main parts: an AEM rubber hose and an electric heating element. An electric heater provides stable heating to the hose, and the internal electric heating element converts electrical energy into heat energy, effectively solving the problems mentioned above. Utility Model Content

It solves the problem that the low temperature in winter can easily cause the oil-gas separator outlet hose to freeze, block the gas outlet, and thus cause the oil-gas separator to malfunction, affecting the reliability and emissions of the engine.

The lead wire is made of high-temperature resistant RV silicone-coated copper core wire, and the heating wire is made of 24V Teflon core spiral heating wire.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1This embodiment describes an antifreeze and heat-insulating electrically heated hose, comprising an electrically heated antifreeze hose body 1. The body 1 consists of an AEM rubber tube 101, a silicone heat-shrinkable tube 102, and a flame-retardant braided mesh tube 103. An electric heater is installed inside the hose body 1. Specifically, the electric heater is composed of a connector, leads, and a heating wire 104. The connector is a male connector 107, and the leads are red and blue leads 106. A flexible thin-film temperature sensor (±0.5℃ accuracy) and a piezoresistive pressure sensor (range 0-10MPa) are embedded in the inner wall of the AEM rubber tube 101. Data is transmitted to the controller via the red and blue leads 106. This allows for real-time monitoring of engine coolant temperature and pipeline pressure, preventing the risk of hose rupture.

[0018] It should be noted that the male connector 107 is fixedly connected to the electric heating antifreeze hose body 1 by a corrugated tube 105, and the lead wire is located inside the corrugated tube 105. The red and blue lead wires 106 are made of high-temperature resistant RV silicone-coated copper core wire, and the heating wire 104 is made of 24V Teflon core spiral heating wire. The heating wire 104 is directly and smoothly fixed to the surface of the AEM rubber tube 101 using special adhesive tape. A flame-retardant braided mesh tube 103 is wrapped around the heating wire 104, and a silicone heat-shrinkable tube 102 covers both ends of the heating wire 104, effectively reducing heat loss and improving insulation efficiency. During use, 24V DC power is transmitted to the heating wire 104 through the red and blue leads 106. Heat is generated through resistance. The Teflon core spiral structure increases the heat dissipation area. Heat from the heating wire 104 is transferred to the internal medium via the AEM rubber tube 101. The silicone heat-shrinkable tube 102 covers both ends of the heating wire 104, reducing heat convection loss and improving insulation efficiency. The flame-retardant braided mesh tube 103 allows a small amount of heat radiation to penetrate, maintaining the surface temperature of the tube. A Kevlar fiber braided layer can be added outside the flame-retardant braided mesh tube 103 to resist puncture by sharp objects.

[0019] Additionally, a capacitive humidity sensor is integrated into the inner wall of the silicone heat shrink tubing 102 to detect condensation buildup and trigger the heating dehumidification mode. A 15A / 250V double-pole circuit breaker is integrated into the male connector 107 to momentarily cut off power in case of overcurrent. A conductive coating is added to the outer layer of the red and blue leads 106 to monitor insulation resistance in real time.

[0020] It is worth mentioning that the electrically heated antifreeze hose body 1 in this application consists of two main parts: an AEM rubber hose 101 and an electric heating component. An electric heater provides stable heating to the hose, converting electrical energy into heat energy through an internal heating element. This heat energy is then transferred to the hose and the medium inside through heat conduction, thereby increasing their temperature. This heating method ensures that the hose and the oil vapor, fuel gas, and other media inside will not freeze due to low temperatures in cold environments, effectively preventing the freezing of the oil-gas separator outlet hose in winter and ensuring the safety and stability of the oil-gas separator. Simultaneously, the design of the electrically heated antifreeze hose also considers insulation and protection requirements, with an outer flame-retardant braided mesh hose 103 and a silicone heat-shrinkable tube 102 to ensure effective heat transfer and safe system operation. The product features excellent antifreeze insulation and a long service life, and is widely used in diesel engine oil-gas separator systems, with even broader application prospects in outlet pipeline antifreeze insulation.

[0021] The working principle of the above embodiments is as follows:

[0022] Use thermally conductive tape to smoothly wrap the heating wire 104 around the outer wall of the AEM rubber tube 101, then insert the flame-retardant braided mesh tube 103 to cover the area of ​​the heating wire 104, leaving a 5cm gap at both ends. Wrap the silicone heat shrink tube 102 around both ends of the heating wire 104, heat it to 150℃ to shrink it and form an airtight seal, then weld the red and blue leads 106 to the male connector 107, insert the corrugated tube 105 and fix it.

[0023] In use, 24V DC power is transmitted to the heating wire 104 through the red and blue leads 106. The resistance effect generates heat. The Teflon core spiral structure increases the heat dissipation area. The heat from the heating wire 104 is transferred to the internal medium through the AEM rubber tube 101. The silicone heat shrink tube 102 covers both ends of the heating wire 104 to reduce heat convection loss and improve heat preservation efficiency. The flame-retardant braided mesh tube 103 allows a small amount of heat radiation to penetrate and maintain the surface temperature of the rubber tube.

[0024] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections.

[0025] Any connection method that can achieve its beneficial effect can be implemented. In addition, all electrical components in this embodiment are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing public power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
