Yuchai Heavy Industry’s three patents were granted by the State

The "YC20 hydraulic excavator" appearance patent, "Paper excavator accessory quick change device" patent, and "Hydraulic excavator water radiator" patent filed by Yuchai Heavy Industries have successfully passed the review of the State Intellectual Property Office of the People's Republic of China. Grant design patents and utility model patents respectively.

The appearance of YC20 hydraulic excavator is a new appearance designed by Yuchai Heavy Industry Engineering and technical personnel according to the company's hydraulic excavator appearance upgrade plan. The appearance of the excavator is smooth, the working light is embedded in the driving shed, and it is a smiley face in front of the driving shed. The bonnet protection board represents the best “B” letter shape.

The quick exchanging device of the hydraulic excavator working device is a new mechanism developed by technical personnel of the Yuchai Heavy Industry Engineering Machinery Research Institute. The excavator driver can realize the attachment of the working device by activating the mechanism on the device through the operation of the mechanism. Installation; The use of a crowbar to pull the lever mechanism on the quick-change device can achieve the disassembly of the working device; one person only needs about 3 minutes to complete the work device attachment replacement, to achieve the purpose of easy and quick replacement. The device has the advantages of high efficiency, reliable performance, simple structure, convenient manufacture and low cost.

The hydraulic excavator water radiator is a new structure developed by the technical staff of the Yuchai Heavy Industry Engineering Machinery Research Institute. This structure eliminates the shutters on the cooling belt and punches the cooling belt into waves, effectively increasing the cooling area. And can effectively prevent dust and debris clogging; and easy to clean and maintain, with a simple structure, easy to manufacture, easy to install and use, practical advantages.

Heat Exchanger

A heat exchanger is a device used to transfer heat, usually to transfer heat from one fluid to another without them mixing. A heat exchanger usually consists of a number of parallel pipes in which one fluid flows through the pipe and another fluid flows through the outside of the pipe. In this way, heat can be transferred from one fluid to another for heating or cooling purposes. Heat exchangers are widely used in many industries, such as chemical, pharmaceutical, food processing, air conditioning and heating systems, etc.

Heat exchanger usually consists of the following components:
1. Heat exchange pipe: Pipe used to transfer heat, usually made of metal materials, such as copper, stainless steel, etc.
2. Heat exchange surface: A surface used to transfer heat, usually consisting of metal sheets or pipes. The greater the surface area, the higher the heat transfer efficiency.
3. Housing: Housing, usually made of metal or plastic, used to secure heat exchange pipes and surfaces.
4. Seals: Seals used to prevent media leakage, usually made of rubber or silicone rubber.
5. Support: A support used to support a heat exchanger, usually made of steel or cast iron.
6. Import and export pipes: pipes used for medium entry and exit, usually made of metal or plastic.
7. Cleaning hole: A hole used to clean the inside of the heat exchanger, usually located on the upper or side of the heat exchanger.
8. Insulation layer: Insulation layer used to keep the temperature of the heat exchanger stable, usually made of glass wool or polyurethane foam.
