Automatic gearshift gearbox is the most popular type of car transmission. As with any active working mechanism, it requires full and complete cooling. What is needed for cooling the ATCP heat exchanger

What is needed for cooling the ATCP heat exchanger

The box is equipped with a large amount of thermal energy (under normal conditions the temperature of the transmission fluid is 10 °C higher than the temperature of the antifreeze liquid in the engine). Therefore, the requirements for maintaining a constant temperature in the ACPT hydraulic environment are very high. In the case of a medium operating environment, an ATF liquid cooling medium is used for the additional cooling radiator of the engine cooling system.

A thermal fluid for transmission fluid is a kind of "reinsurance" for a producer who understands that a car that they have created will want to "try out" in marginal modes

In regions with a high temperature of air and in cars, where the natural abundance of gearboxes is difficult to make noise, an additional heat exchanger is provided to allow for more intense cooling. The condition of noise reduction from the work of transmission is especially relevant for executive cars, and these cars have been equipped with powerful engines and, as a consequence, designed for their capacity by gearboxes. Therefore, the additional heat exchanger is most often found in the design of large, high-value sedans and sports, where all the nodes are designed to operate in extreme operating modes.

Location of the APCIP heat exchanger

In modern cars, the rear heat exchanger (heat exchanger) is most likely to be integrated into the power cooling radiator. The additional heat exchanger shall be installed where the flow of the running air is usually before the engine cooling radiator.

The heat exchanger is not able to handle its direct functions, it also creates an additional obstacle to the flow of the transmission fluid

Before getting into the heat exchanger, the transmissive oil does a long way. The oil-filter is placed in the oil filter pan through the ACPR pallet and the oil pass through the control valves, then into the shell of the control valves, and then to the working pistons of the bags, then passes through the hydraulic transformers from which it enters the heat exchanger. The chilled transmissive oil comes back to the ACPR pallet.

Questions of operation of the ATCP heat exchanger

As a general rule, the state of the ACPR heat exchanger is not very much the case even after the transfer of the gearshift gearbox. The heat exchanger may be contaminated not only from the outside but also from the inside. If it is "beaten" outside, the ability to heat the box is reduced as the area of contact with the air is decreasing. If on the inner surface of the tubes a flare is made, it stops passing through itself the transmission fluid in sufficient volume. As a result, the effect of a hydraulic converter overflow may occur-a full or partial lock on that device may occur. In this case, the gearshift is broken. Inside the heat exchanger, creates dangerous conditions in the work of ACPR: the friction protectors that replace the ACPR, are rapidly heated and quickly heated, and the wear products fall into the transmission filter by clogging it. All this could lead to premature rerepairs of the ACPR.

Operating characteristics of the HCOC heat exchanger

There is a simple and many-tested method of cleaning the heat exchanger from the inside. It requires special equipment to be pummalized through a cleaning machine. In order to connect to the stand, the rubber tubes must be disconnected from the cooling system. The hose assemblies are attached to the mounting hardware. The pressure pump shall be actively brainwashing the heat exchanger with the special liquid, then with the air compressor the internal volume of the heat exchanger dried.

For effective prevention, it is recommended to launder the heat exchanger from the inside whenever the ATF liquid is replaced in the automatic box

There are two ways to clean the heat exchanger from the outside. If access to it is not complicated by attachments (such as a bumper), it can be washed with water with the help of "kerher", without taking off the car. If this is not possible, the heat exchanger must be removed. In general, this method is preferable, as it allows the removal of all the debris in the sludge.
