Abstract
The invention belongs to the technical field of aviation, and relates to a heating device special for an aircraft lubricating oil tank. At present, most of existing heating devices adopt an insertion type structural form, and as aviation lubricating oil belongs to combustible liquid, the existing heating devices can be in direct contact with lubricating oil, so that fire hazards are caused. The invention provides a heating device for heating a heating component and lubricating oil after the heating component is isolated from the lubricating oil by utilizing a thermal radiation principle. The high-efficiency heat transfer of the heating device is ensured; the heating device can be used independently or simultaneously in multiple groups according to heating requirements, and has the advantages of simple structure, convenience in disassembly and good interchangeability.
Description
Technical Field
The invention belongs to the technical field of aviation, and relates to a heating device special for an aircraft lubricating oil tank.
Background
The lubricating oil tank heating device is mainly used for keeping the temperature of lubricating oil in the lubricating oil tank within a certain range in a low-temperature environment, so that the lubricating oil system can normally work in the low-temperature environment. The heating device generally includes a heating assembly, a mounting base, and wires.
At present, most of existing heating devices adopt an insertion type structure form, as shown in fig. 1, a heating assembly is directly inserted into liquid of a lubricating oil tank to heat the liquid, and as aviation lubricating oil belongs to combustible liquid, the existing heating devices can be in direct contact with the lubricating oil, so that fire hazards are caused.
Disclosure of Invention
The invention overcomes the defects in the prior art and provides the heating device which utilizes the heat radiation principle to isolate the heating component from the lubricating oil and then heats the lubricating oil.
The utility model provides a be exclusively used in heating device of aircraft lubricating oil tank, the device is through heating outside the lubricating oil tank, including controller and install the housing part at the lubricating oil tank surface, is equipped with a plurality of heating plates in the surface of this housing part, installs the platinum resistor that detects heating plate surface temperature on the heating plate surface, and when reaching first settlement temperature value, the platinum resistor sends outage signal to the controller.
The outer surface of the shell part is also provided with a temperature relay for detecting the surface temperature of the shell part, when a second set temperature value is reached, the temperature relay sends a power-off signal to the controller, and the second set temperature value is higher than the first set temperature value.
The housing part is shaped to match the profile of the lubricant tank and has a sleeve at the end which is connected to the lubricant tank.
And a lead wire communicated with the heating sheet is arranged on the shell component.
The shell part is made of aluminum alloy materials.
Has the advantages that: the invention provides a heating device, wherein the shell part of the heating device is made of an aluminum alloy material, and has better manufacturability and thermal conductivity; the platinum resistor and the temperature relay can effectively ensure that the heating device always works in a safe temperature range; the sleeves at the two ends are matched with the T-shaped bolt and the nut on the oil tank for use, so that the gap between the heating device and the bottom of the oil tank can be conveniently adjusted, the good contact between the heating device and the oil tank is ensured, and the efficient heat transfer of the heating device is ensured; the heating device can be used independently or simultaneously in multiple groups according to heating requirements, and has the advantages of simple structure, convenience in disassembly and good interchangeability.
