Heat conduction, heat convection and heat radiation. The transfer of energy between matter itself or when matter comes into contact with matter is called heat conduction, which is the most common form of heat transfer. For example, the way the heat sink base is in direct contact with the heat sink is thermal conduction. Thermal convection refers to the heat transfer method in which flowing fluid (gas or liquid) takes away heat. In the cooling system of a computer case, a common method is forced convection heat dissipation in which a cooling fan drives the flow of gas. Thermal radiation refers to the transfer of heat by ray radiation, and the most common daily radiation is solar radiation. These three heat dissipation methods are not isolated. In daily heat transfer, these three heat dissipation methods all occur at the same time and work together.
Hydraulic oil radiators are used in construction machinery that uses hydraulic oil as the power transmission medium, such as: excavators, concrete pumps, fine mortar pumps, boom pumps, vehicle-mounted pumps, pile drivers, trenchers, and rotary diggers. Drilling rigs, pavers, trenchless equipment, air compressors, road rollers, etc. This series of products is mainly used in the circuit of hydraulic systems. During operation, the high-temperature oil in the hydraulic system flows through the hydraulic oil cooling device, and performs efficient heat exchange with the forced flow of cold air in the heat exchanger, reducing the oil temperature to the operating temperature to ensure that the main engine can continue to operate normally, so that the work can successfully launch.
During the installation process of the small crane, the ground clearance and radiator problems need to be solved:
These all involve safety issues, so pay more attention to them. In order to ensure the ground clearance after the installation of the small crane, the connection between the rear part of the engine and the transmission input shaft should be appropriately raised. The front and rear connecting brackets are thickened by 3 respectively. The water inlet of the radiator is on the upper part, one on the left and one on the left. , respectively connected to the water outlet pipes of the cylinder heads on the left and right sides of the engine. There is only one water inlet of the radiator in the upper middle, which is connected to the water outlet pipes of the cylinder heads on both sides through the thermostatic device in the middle. Among them, because the small crane radiator is installed at the lower part of the cab, the connection method and fixing device are not easy to change, so it is very difficult to replace the radiator. Use the original radiator. Notice that the original radiator is convenient for replenishing cooling water. There is a water inlet in the middle of the upper part, which is led out through a section of water adding pipe. This inlet can be used as a water inlet, connected to the water outlet of the engine, and one of the two original water inlets can be sealed. The other one is led out with a section of water pipe to replenish cooling water. The location of the water outlet pipe is the same, at the bottom, without any modification.
Small crane radiator material:
The radiator material refers to the specific material used for the radiator. Each material has different thermal conductivity properties. They are arranged from high to low thermal conductivity, namely silver, copper, aluminum, and steel. However, it would be too expensive to use silver as a heat sink, so the best solution is to use copper. Although aluminum is much cheaper, it obviously does not conduct heat as well as copper (about 50% less). Commonly used heat sink materials are copper and aluminum alloys, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, difficult to process, too heavy (many pure copper radiators exceed the weight limit), has small heat capacity, and is easily oxidized. Pure aluminum is too soft and cannot be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than that of copper. Some radiators take advantage of their own strengths and embed a copper plate in the base of the aluminum alloy radiator. For ordinary users, using aluminum heat sinks is enough to meet heat dissipation needs.
