Fuel Cell System Water-Cooled Intercooler ZLQ Series 5~200kW High Efficiency Heat Exchange Low Flow Resistance Insulated Mounting

Quick Detail:

• Liquid-cooled intercooler developed for proton exchange membrane fuel cell (PEMFC) systems
• Applicable power range: covering 5~200kW fuel cell systems
• Working principle: forced cooling of the high-temperature air pressurized by the air compressor through the main cooling system water circuit
• Uses optimally matched cooling fins to improve heat exchange efficiency
• The heat exchanger uses a continuous brazing process, reducing weight while improving heat exchange efficiency
• Ion concentration precipitation inside the heat exchanger is controlled; after deionization treatment the ion concentration is always kept at an extremely low state
• Four fixing points use insulator mounting, ensuring an insulation level with the vehicle of >=200MOhm@500V
• Working temperature range: air side -30C~190C, coolant side -30C~92C
• Working pressure: air side / coolant side <=300kPa (up to 600kPa for a short time)
• The body is made of all-aluminum material (3003/4045/4343 aluminum alloy) with silver paint anti-corrosion treatment
• Complies with the standards QC/T 468-2010 Automotive Radiator and GB/T 23338-2018 Technical Conditions for Charge Air Coolers of Internal Combustion Engines

Description:

The ZLQ series water-cooled intercooler is installed between the air compressor and the fuel cell stack, and forcibly cools the charge air through the low-temperature coolant of the main cooling system. Its core heat exchange principle is as follows: high-temperature compressed air flows through the air-side channel, low-temperature coolant flows through the water-side channel, and the two perform efficient heat exchange through high-thermal-conductivity aluminum alloy fins and cooling tubes, reducing the air temperature to the allowable range at the stack inlet while keeping the system running stably at a constant temperature.

This series of intercoolers has the following outstanding features: first, an optimally matched cooling fin design maximizes the heat exchange area within a limited space; second, the continuous brazing process ensures a metallurgical bond between the components of the core, significantly improving heat exchange efficiency and structural strength; third, strict control of ion concentration precipitation ensures that the coolant ion concentration is always kept at an extremely low state after deionization treatment, avoiding contamination of the stack; fourth, the four fixing points use insulator mounting, insulating the heat exchanger housing from the fixing bolts and ensuring an insulation level with the vehicle of >=200MOhm@500V, meeting the high-voltage safety requirements of the fuel cell system.

FAQ

Q1: Can you provide samples for testing?
A: Yes, we support sample orders for vehicle installation testing and performance verification, and also accept mixed-model sample orders.

Q2: What is the delivery lead time?
A: Sample orders usually take 5-7 working days; bulk orders (depending on order quantity) generally take 15-30 working days.

Q3: Is there a minimum order quantity (MOQ) limit?
A: There is no strict MOQ limit; 3-piece sample trial orders are supported, and bulk order prices are more favorable.

Q4: Why does a fuel cell system need an intercooler?
A: After the air compressor pressurizes the air, the temperature can rise to 150~190C, while the PEMFC stack usually requires the inlet air temperature not to exceed 70C. High-temperature air directly entering the stack will accelerate membrane electrode aging and reduce system efficiency. The intercooler reduces the air to a suitable stack temperature through water-to-air heat exchange and is the core thermal management component ensuring stable system operation.

Q5: What is the material of the intercooler?
A: The whole body is made of aluminum alloy, including the header plate, cooling tubes, cooling fins, air chamber and water jacket, with silver paint anti-corrosion treatment, offering good thermal conductivity and corrosion resistance.

Q6: What are the insulation requirements of the intercooler?
A: The four fixing points use insulator mounting, insulating the heat exchanger housing from the fixing bolts, ensuring an insulation level with the vehicle of >=200MOhm@500V (ZLQ-066 series) or >=500MOhm@1000V (ZLQ-055 series), meeting the high-voltage safety requirements of the fuel cell system.

Q7: How should the intercooler be installed?
A: The intercooler should be installed horizontally with an installation torque of 15~20N.m. The mounting base structure should be able to withstand the vibration and impact of the heat exchanger. Pay attention to the center of gravity during installation; tilting or inverting is strictly prohibited to prevent impact or sharp lifting.

Q8: How to handle product failures?
A: We implement a strict quality control system, with an out-of-factory defect rate below 0.2%. During the warranty period, small batches of defective products will be replaced with new ones in the next order; batch quality problems will be negotiated for repair or replacement to ensure customer rights.
