Small intercooler

Types of Small Intercooler

A small intercooler is a heat exchange device used to cool compressed air before it enters the engine. The cooled air has a high density, and this helps to improve engine performance. Small intercoolers are ideal for small cars with small turbochargers. They are categorized based on their placement and design.

• Intercooler placement

  The first type is the air-to-air intercooler. This intercooler uses air flow to cool the compressed air. The small intercooler is placed after the turbocharger, and its core is surrounded by metal fins. When the car is in motion, air passes through the metal fins and cools the core. The degree of cooling depends on the ambient temperature and the intercooler's position relative to the airflow.

• Water-to-liquid intercooler

  Water-to-liquid small intercoolers are mostly used in racing cars. They have a higher cooling capacity than air-to-air intercoolers. The cooled air gets transferred to a reservoir filled with water. The water is then pumped through a small radiator. The radiator removes the heat from the water, which is then returned to the reservoir. The coolant in the reservoir is usually at a lower temperature than the air in the intercooler. This setup allows the water to absorb the heat from the air, which lowers the temperature of the air before it enters the engine.

• Intercooler design

  Bar and plate intercoolers are designed with a series of bars and plates that create channels. The compressed air and coolant flow through the channels. These intercoolers are durable and can withstand high pressure. They also have a lower pressure drop, which means they can maintain higher pressure in the intake.

• Tube and fin

  intercoolers have a simpler design with tubes and metal fins. The tubes are connected to the intercooler core and the metal fins, which are responsible for the heat transfer. Tube and fin intercoolers have a lower manufacturing cost and are lightweight. However, they are not very efficient and are suitable for applications where efficiency is not a top priority.

• Vertical and horizontal small intercoolers

  The vertical intercooler is designed to maximize the cooling effect by allowing the air to pass through the core from top to bottom. This creates a chimney effect that improves the cooling efficiency. On the other hand, horizontal intercoolers have a core that is wider than it is tall. This design maximizes the surface area of the core that is exposed to the oncoming air, resulting in better cooling.

Specifications and maintenance of small intercooler

Here are the specifications to be aware of when purchasing a small car intercooler:

• Size

  Small intercoolers are compact, but they still come in different sizes. The size is measured in terms of length, height, and width. A small intercooler has a length between 400 and 700 mm, a height of 200 mm, and a width of 100 mm. The dimensions affect the intercooler's performance and fit within the vehicle.

• Cooling method

  The small intercooler uses ambient air to cool the compressed air from the engine. The temperature drop is achieved through the heat exchange process. The temperature difference between the compressed air and the intercooler cools the compressed air.

• Material

  Intercoolers are made using aluminum, which is lightweight, and offers good thermal conductivity. The aluminum intercooler can quickly cool the compressed air without adding much weight.

• Core design

  The intercooler core is designed with parallel flow or bar and plate configurations. The cores enhance the air flow and cooling performance.

• Fin

  The intercooler fins are integral to heat dissipation. They are designed with louvered or offset patterns, which maximize the heat exchange surface area.

• Inlet and outlet size

  The intercooler inlet and outlet ports are compatible with the vehicle's intercooler piping. The inlet and outlet diameter range from 50 to 76 mm.

• Pressure drop

  Pressure drop is the reduction of pressure as the compressed air passes through the intercooler. For small intercoolers, the pressure drop is measured in bars and should be low, between 0.2 and 0.5 bar.

• Cooling capacity

  Cooling capacity refers to the intercooler's ability to cool the air. It is measured in watts or kilowatts. Small intercoolers have a cooling capacity of 2000 to 4000 watts.

• Heat transfer

  The heat transfer rate is the amount of heat transferred from the compressed air to the ambient air. It is measured in watts per degree Celsius. The heat transfer rate of small intercoolers is between 1000 and 2000 watts per degree Celsius.

• Tuning

  The intercooler is compatible with different tuning options. This is important for buyers who want to customize the intercooler for specific performance needs. The small intercooler can be used in vehicles with standard tuning or customized for high-performance vehicles.

Here are some small intercooler maintenance tips:

• Regularly inspect the small intercooler for leaks, physical damage, or blockages. Early detection of leaks can help prevent serious engine problems. Users should pay attention to the intercooler fins since they are easy to damage and can affect the cooling performance of the intercooler.
• Ensure nothing blocks the small vehicle intercooler since it can affect its cooling performance. Also, remove any debris, dirt, and bugs that may inhibit the intercooler's ability to cool the air.
• Ensure the small front intercooler is securely mounted to prevent vibrations that may cause physical damage to the intercooler.
• Check the intercooler piping for signs of wear, damage, or leaks. Replace damaged pipes and ensure all connections are tightly sealed to prevent leaks.
• Ensure the small turbo intercooler is properly aligned with the inlet and outlet pipes. Improper alignment can lead to increased pressure drop and reduced cooling efficiency.
• Ensure the small intercooler is periodically removed and cleaned to enhance its cooling performance. Use mild soap and water when cleaning the intercooler.
• Follow the manufacturer's instructions for maintenance and care. The guidelines ensure the intercooler is maintained in good working condition and enhances its lifespan.

How to Choose Small Intercoolers

Buying a small intercooler is not as straightforward as it may seem. There are several factors buyers need to consider to get the right intercooler for their needs. Here are some of them:

• Vehicle Specifications

  Choose intercoolers that are compatible with the pipe size and mounting options of the specific vehicle. Also, consider the vehicle's engine size and tuning modifications, if any. Cars with more powerful engines need larger intercoolers.

• Cooling Requirements

  Determine the cooling capacity required based on the boost levels and the type of small turbo intercooler configuration supported by the vehicle. A larger intercooler offers better cooling but may affect the space available for installation.

• Pressure Drop

  Small intercoolers with a larger cores have a lower pressure drop. This means they will not impede airflow from the turbo to the engine. When choosing an intercooler, consider the pressure drop to avoid losing power from the engine.

• Material and Construction

  Choose intercoolers made from strong materials like aluminum. Aluminum is resistant to corrosion and has a high strength-to-weight ratio. This makes intercoolers last longer and minimizes the added weight to the vehicle.

• Core Design

  Consider the type of small intercooler core configuration and its impact on cooling efficiency. Bar and plate cores are known for their durability and are ideal for applications that require strength. However, they are heavier than tube-and-fin cores.
