Abstract
The utility model provides a kind of volute containing thermal insulation layer, including volute body, coolant inlet, cooling liquid flowing channel, cooling liquid outlet.Wherein, the whirlpool enclosure interior is provided with cooling liquid flowing channel, and the both ends of the cooling liquid flowing channel are respectively the coolant inlet and the cooling liquid outlet, and thermal insulation layer is provided in the cooling liquid flowing channel.Volute provided by the utility model containing thermal insulation layer in cooling liquid flowing channel by being arranged thermal insulation layer, to reduce temperature when volute body running, to ensure that the operating temperature of turbine is not higher than 650 °.
Description
Technical field
The utility model is related to a kind of turbocharger, and in particular to a kind of volute containing thermal insulation layer.
Background technology
Turbocharger is the important component for improving power of IC engine, reducing consumption rate of fired oil, improving discharge.The energy increasingly
Today of shortage, environment worsening, exhaust gas turbocharge have become the only way which must be passed of internal combustion engine development.Cylinder for petrol engine
The exhaust gas temperature of discharge is up to 1000 DEG C or more, and turbocharger, under the conditions of continuous high temperature, volute often will appear high temperature
Phenomena such as creep, cracking.
Utility model content
The utility model provides a kind of volute containing thermal insulation layer, warm when in use to solve volute of the existing technology
Spend high problem.
In order to solve the above technical problems, the utility model provides a kind of volute containing thermal insulation layer, including volute body, cooling
Liquid entrance, cooling liquid flowing channel, cooling liquid outlet.Wherein, the whirlpool enclosure interior is provided with cooling liquid flowing channel, the cooling liquid stream
The both ends in road are respectively the coolant inlet and the cooling liquid outlet, and thermal insulation layer is provided in the cooling liquid flowing channel.
Preferably, the thermal insulation layer is sand core.
The advantageous effect that the utility model is brought：Volute provided by the utility model containing thermal insulation layer passes through in coolant liquid
Thermal insulation layer is set in runner, to reduce temperature when volute body running, to ensure that the operating temperature of turbine is not higher than 650 °.
Description of the drawings
Fig. 1 is the overall structure diagram according to the volute containing thermal insulation layer of the utility model embodiment.
Fig. 2 is the sectional view of the A-A in Fig. 1 according to the utility model embodiment.
Wherein, 1- volutes body, 2- coolant inlets, 3- cooling liquid flowing channels, 4- cooling liquid outlets.
Specific implementation mode
To keep the purpose of this utility model, technical solution and advantage clearer, below in conjunction with drawings and the specific embodiments,
The utility model is described in further detail.
Fig. 1 is the overall structure diagram according to the volute containing thermal insulation layer of the utility model embodiment.Fig. 2 is basis
The sectional view of A-A in Fig. 1 of the utility model embodiment.
As depicted in figs. 1 and 2, a kind of volute containing thermal insulation layer provided by the utility model, including volute body 1, cooling
Liquid entrance 2, cooling liquid flowing channel 3, cooling liquid outlet 4, the volute body 1 are internally provided with cooling liquid flowing channel 3, the cooling liquid stream
The both ends in road 3 are respectively the coolant inlet 2 and the cooling liquid outlet 4, are provided in the cooling liquid flowing channel 3 heat-insulated
Layer.
Furthermore, it is understood that the thermal insulation layer is sand core, when the volute body 1 molds, increase the mold of a secondary thermal insulation layer core,
The sand core is placed when casting can form the thermal insulation layer.Thus, temperature when reducing volute body running by thermal insulation layer,
To ensure that the operating temperature of turbine is not higher than 650 °.
In conclusion the volute provided by the utility model containing thermal insulation layer is heat-insulated by being arranged in cooling liquid flowing channel
Layer, to reduce temperature when volute body running, to ensure that the operating temperature of turbine is not higher than 650 °.
The above description is only the embodiments of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the right of the utility model.
