Description
Technical Field
The utility model belongs to the water heater field, concretely relates to thick film cartridge heater.
Background
A water heater is a heating device commonly used by people, and the heater conventionally generates heat in the form of combustible gas and burning biomass particles to heat water for use or heating. The mode of adopting above-mentioned burning heating can produce waste gas and particulate matter, and is big to air pollution. Therefore, heaters using electric energy for heating are becoming more and more popular in people's lives.
Among them, the water storage type water heater is most widely used. However, most of the heating elements of the water storage type water heaters adopt an electric heating pipe to directly heat the water body. The electric heating pipe of the water heater adopting the heating mode is directly contacted with water, scale is easy to be formed on the surface, and pipe explosion and leakage accidents can occur after long-term use. And the storage type water heater needs to be opened in advance for heating for a long time before being used. And the capacity of the water tank is limited, and the water temperature is gradually reduced along with the reduction of hot water in the water tank, so that the temperature is unstable.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problems existing in the prior art, the utility model aims to provide a thick film heating cylinder, which is a heating element of a water heater. The heating oil cylinder is arranged in the outer cylinder, the thick film heating component is tightly attached to the outer wall of the heat conduction oil cylinder, the upper end and the lower end of the outer cylinder are respectively provided with the sealing cylinder covers, the heating water pipe is arranged in the middle of the heat conduction oil cylinder, and the water inlet end and the water outlet end of the heating water pipe are respectively extended out of the sealing covers at the lower end and the upper end.
From this, fill the conduction oil in the conduction oil section of thick bamboo, the conduction oil has good thermal stability, thermal uniformity and insulating nature, thick film heating element heats the conduction oil rapidly during the heating, water carries out even intensification after the heat transfer through the conduction oil of heating water pipe after with the heating, avoid with the thick film heating element between the contact to prevent the electric leakage accident, and because thick film heating element separates with the water, consequently can not knot the incrustation scale yet. The heat conduction oil can play a certain buffering role even if no water exists in the heating pipe, and the thick film heating component is prevented from being dried.
In one embodiment, the part of the pipe body of the heating water pipe, which is positioned on the heat-conducting oil cylinder, is a spiral pipe. The spiral pipe is favorable for more uniform heat exchange between the heating water pipe and the heat conduction oil, and keeps the water temperature constant.
In one embodiment, the wall of the outer barrel is provided with a hollow heat insulation layer. The hollow heat insulation layer can delay the loss of heat and save energy.
The utility model discloses the beneficial effect who possesses: the utility model discloses a thick film cartridge heater is arranged in the water heater as heating element. Through filling the conduction oil in the conduction oil cylinder, utilize the good thermal stability of conduction oil, thermal uniformity and insulating nature, thick film heating element heats the conduction oil rapidly during the heating, water evenly heaies up after carrying out the heat transfer through the conduction oil of heating water pipe after with the heating, avoid with the thick film heating element between the contact to prevent the electric leakage accident, and because thick film heating element is separated with the water, consequently can not knot the incrustation scale yet. The heat conduction oil can play a certain buffering role even if no water exists in the heating pipe, and the thick film heating component is prevented from being dried.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1-3, a thick film cartridge heater is a heating element for a water heater. The heating oil cylinder comprises an outer cylinder 1, a heat conduction oil cylinder 2, a sealing cylinder cover 3, a thick film heating assembly 4 and a heating water pipe 5, wherein the heat conduction oil cylinder 2 is arranged in the outer cylinder 1, the thick film heating assembly 4 is tightly attached to the outer wall of the heat conduction oil cylinder 2, the upper end and the lower end of the outer cylinder 1 are respectively provided with the sealing cylinder cover 3, the heating water pipe 5 is arranged in the middle of the heat conduction oil cylinder 2, and the water inlet end and the water outlet end of the heating water pipe 5 are respectively extended out from the sealing covers 3 at the lower end and the upper.
From this, fill the conduction oil in heat conduction oil cylinder 2, the conduction oil has good thermal stability, thermal uniformity and insulating nature, thick film heating element 4 heats the conduction oil rapidly during the heating, water carries out even intensification after the heat transfer through the conduction oil after water heating pipe 5 and the heating, avoid with the thick film heating element 4 between the contact, thereby prevent the electric leakage accident, and because thick film heating element 4 is separated with the water, consequently can not knot the incrustation scale yet. Even if no water is in the heating water pipe 5, the heat conduction oil can play a certain buffering role, and the thick film heating component 4 is prevented from being dried.
The heating water pipe 5 is a spiral pipe at the part of the heat conducting oil cylinder 2. The spiral pipe is favorable for more uniform heat exchange between the heating water pipe 5 and the heat conduction oil, and keeps the water temperature constant.
