Structural design for eliminating abnormal waterflow sound of heat exchanger of automobile

Abstract

The invention discloses a structural design for eliminating abnormal waterflow sound of a heat exchanger of an automobile. The structural design comprises a cooling system, wherein the cooling systemcomprises a thermolator base, a water storage bottle, a bypass valve, the heat exchanger, a first pipeline for hermetically communicating with the thermolator base and the heat exchanger, a second pipeline for hermetically communicating with the thermolator base and the bypass valve, and a third pipeline for hermetically communicating with the thermolator base and a turbocharger, wherein the connection position of the bypass valve and the heat exchanger to the thermolator base is exchangable top and bottom; the second pipeline hermetically communicates with the upper right side of the thermolator; and the first pipeline hermetically communicates with the lower right side of the thermolator. According to the structural design, the hermetical communicating position of the heat exchanger andthe thermolator base is changed, so that layered bubbles are isolated so as not to enter into the heat exchanger through the first pipeline; and moreover, abnormal sound of a core body of the heat exchanger due to the bubbles when the automobile is cold started is avoided, and the driving experience is improved.

Description

technical field [0001] The invention relates to the technical field of a cooling system for an automobile turbocharged engine, in particular to a structural design for eliminating the abnormal sound of water flow in an automobile heat exchanger. Background technique [0002] Turbocharged engines are being used more and more because of their low fuel consumption and strong power. When a turbocharged engine needs to output a large torque, it generally needs to increase the number of revolutions of the engine to above 3000rpm, and after reaching the above number of revolutions, the temperature of the turbocharger and the engine is very high. The turbocharged engine cooling system is responsible for providing cooling for the turbocharged engine and ensuring the normal and reliable operation of the engine. Existing turbocharged engine cooling systems are usually water-cooled closed circulation systems. Such as figure 1 with figure 2 Shown: The cooling system of the turbochar...

Problems solved by technology

[0004] Therefore, when the car is restarted under the condition of a cold car, a large amount of air bubbles generated by the coolant will flow into the core of the heat exchanger through the cooling pipe, and the core of the heat exchanger will produce a "squeak" due to the rupture of the air bubbles. "The discontinuous sound of running water caused abnormal noise inside the vehicle, which seriously affected the driving experience of the drivers and passengers.
