AI Technical Summary

Technical Problem

Traditional oil coolers cannot ensure the stability of the oil pressure in the event of a failure, which affects the lubrication effect and leads to unstable operation of the diesel engine.

Method used

A cooler cover with integrated bypass function is designed. By setting a bypass valve between the front and rear oil passages of the cold front oil passages, the bypass valve is opened when the pressure exceeds the set pressure, and some engine oil directly enters the cold rear oil passages to avoid entering the cooler core, thereby maintaining the stability of the engine oil pressure.

Benefits of technology

In the event of a fault, the design of the bypass valve can effectively maintain the stability of the engine oil pressure, ensure that the lubrication effect is not affected, and ensure the stable operation of the diesel engine.

Description

Technical Field

[0001] The utility model relates to the technical field of engine oil coolers, in particular to a cooler cover with an integrated bypass function. Background Art

[0002] The oil cooler plays a vital role in the lubrication system. It plays a decisive role in ensuring the temperature of the oil entering the engine body, and ensuring the cooling of the oil is the basis for achieving this role. After the oil is cooled, the temperature drops and the pressure decreases. In addition, the oil cooler in the engine is mostly a plate-fin cooler with a high flow resistance. Therefore, the premise of ensuring the cooling of the oil is that the oil will not drop too much due to excessive flow resistance, resulting in insufficient pressure at each lubrication point of the diesel engine. Therefore, it is extremely important to ensure the stability of the oil pressure during the cooling process.

[0003] Traditional oil coolers come in different forms, but most of them use two media to achieve heat exchange through their respective inlets and outlets. If a malfunction occurs, such as oil blockage, the oil pressure cannot be guaranteed, which in turn affects the lubrication effect. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a cooler cover with an integrated bypass function, which can ensure the stability of the oil pressure in the event of a fault without affecting the lubrication effect, ensure the stable operation of the diesel engine, and effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cooler cover with an integrated bypass function, comprising an oil cooler cover, wherein the oil cooler cover comprises a front cold oil passage, a rear cold oil passage, a bypass valve, an oil cooler core inlet and an oil cooler core outlet, the front cold oil passage is communicated with the oil cooler core inlet, the oil cooler core inlet and the oil cooler core outlet are respectively arranged at two ends of the oil cooler core, the oil cooler core outlet is communicated with the rear cold oil passage, a bypass valve is arranged between the front cold oil passage and the rear cold oil passage, and the bypass valve is located between the front cold oil passage and the oil cooler core inlet.

[0006] As a preferred technical solution of the utility model, the rear cooling oil passage is communicated with the main engine oil passage of the engine body.

[0007] As a preferred technical solution of the utility model, when the pressure is normal, the bypass valve is closed, and the engine oil enters the oil cooler core through the front oil channel and the inlet of the oil cooler core to be cooled.

[0008] As a preferred technical solution of the utility model, when the pressure exceeds the set pressure, the bypass valve opens, and part of the oil does not pass through the oil cooler core, but directly enters the cold rear oil channel from the cold front oil channel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the cooler cover with integrated bypass function is reasonably designed, a bypass valve is arranged at the oil inlet passage of the oil cooler cover, and the pressure is set at an oil pressure that satisfies the normal lubrication of various components of the lubrication system. When the pressure is exceeded, the bypass valve opens, and the oil passes through the bypass valve and directly enters various lubrication points for lubrication; when the pressure is lower than the set pressure, the bypass valve closes, and the oil enters the main oil passage of the engine after being cooled by the oil cooler, thereby achieving stable oil pressure in the event of a fault.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-2 The utility model provides a technical solution: a cooler cover with an integrated bypass function, comprising an oil cooler cover, the oil cooler cover comprising a front cold oil passage 1, a rear cold oil passage 2, a bypass valve 3, an oil cooler core inlet 4 and an oil cooler core outlet 5, the front cold oil passage 1 is communicated with the oil cooler core inlet 4, the oil cooler core inlet 4 and the oil cooler core outlet 5 are respectively arranged at two ends of the oil cooler core, the oil cooler core outlet 5 is communicated with the rear cold oil passage 2, the rear cold oil passage 2 is communicated with the main oil passage of the engine body, a bypass valve 3 is arranged between the front cold oil passage 1 and the rear cold oil passage 2, and the bypass valve 3 is located between the front cold oil passage 1 and the oil cooler core inlet 4.

[0015] Under normal pressure conditions, the bypass valve 3 is closed, and the oil is input into the oil cooler body through the front oil channel 1. After the oil enters the oil cooler core through the oil cooler core inlet 4 and is cooled, it flows into the rear oil channel 2 from the oil cooler core outlet 5 and then enters the main oil channel of the engine body.

[0016] After the pressure exceeds the set pressure, the bypass valve 3 opens, and part of the oil entering from the cold front oil channel 1 flows into the cold rear oil channel 2 through the bypass valve 3 without entering the oil cooler core. When the oil pressure gradually decreases to the normal oil pressure, the bypass valve 3 closes, realizing the bypass function of the oil cooler cover and ensuring the stability of the oil pressure when oil blockage occurs.
