Modine Company has launched its new EVantage series of electric compressors and valves for commercial vehicles.

EVantage High-Voltage (HV) Electric Compressor: A highly adaptable, intelligent product that plays a critical role in the electric vehicle’s refrigeration circuit, regulating the flow of coolant to the battery pack or the air for the cabin heating, ventilation, and air conditioning (HVAC) system. Designed to be lightweight yet robust, it ensures stable performance and electrical integrity even under harsh operating conditions.

Functions and Advantages of the Hydraulic Retarder Heat Exchanger

The hydraulic retarder’s heat exchanger is the core cooling component of the device, and its functions and advantages are critical for ensuring vehicle braking safety and enhancing operational efficiency.

Installation and Maintenance of Oil Coolers

Oil coolers are widely used oil‑cooling devices in power systems and are also suitable for applications in metallurgy, chemical processing, mining, light industry, and heavy industry. Now, let’s take a closer look at the installation, operation, and maintenance of oil coolers.

Causes of leakage in oil coolers, whether water or oil leaks

During the operation of the unit, the oil cooler supplied by the manufacturer may experience leaks at the bottom end cover—either water or oil. Such failures are particularly common during startup and shutdown. Let us now explain the underlying causes.

What are the advantages of an oil cooler?

To ensure adequate cooling of the turbine oil during operation, the tandem oil cooler consists of two oil coolers of equal surface area and a three-way valve, allowing one unit to operate while the other serves as a standby. When high oil temperature or elevated inlet water temperature results in reduced cooling efficiency, both units may be put into service simultaneously. Alternatively, during routine cleaning or maintenance of the oil cooler, the standby unit can be activated without shutting down the system.

What are the characteristics of an oil cooler?

Depending on the installation configuration, oil coolers are classified as vertical or horizontal types. Vertical oil coolers feature a compact footprint and ease of installation, while horizontal oil coolers offer lower pressure drop and superior resistance to water hammer. Therefore, selecting the appropriate type—vertical or horizontal—based on site constraints, available headroom, operational requirements, and other factors will better meet the needs of turbine‑generator sets and other equipment.

How to Select the Heating and Cooling Fluids for a Cooler

When using a cooler to handle the heating and cooling of materials, it is also necessary to consider the selection of the heating medium (heat source) and the cooling medium (cold source). A wide variety of fluids can serve as heating or cooling agents; common heating media for shell-and-tube coolers include saturated steam, flue gas, and hot water. Typical cooling media include water, air, and nitrogen. When choosing heating and cooling agents, the primary factors to consider are ease of procurement, adequate temperature levels, cost-effectiveness, and operational safety.

How is cooling carried out in plate heat exchanger manufacturing?

Plate heat exchangers feature a large heat-transfer surface area, a compact structure, and outstanding performance. In general, they are well suited for cooling low-viscosity, relatively clean oils and have already earned widespread recognition across many industries. So how exactly does this type of cooler operate? The following provides a detailed explanation. A plate heat exchanger is a type of shell-and-tube heat exchanger and is a commonly used oil-cooling device in power systems. It enables heat exchange between two liquid media with a temperature difference, thereby reducing oil temperature—particularly effective for turbine oil cooling—and ensuring the reliable operation of equipment such as steam turbines.
