Air to air heat exchanger manufacturer from china

Product Introduction

Air to air heat exchanger is a device with two independent airflow channels, which are design with a cross structure. Channel A discharges indoor air, while Channel B sends fresh outdoor air into the room. Cold and hot air exchange heat in the heat exchanger, reducing the operating load of the air conditioner and achieving energy-saving and emission reduction effects

The main material used for this type of heat exchanger is plain aluminum foil, which is pressed into the desired shape using a hydraulic press, then manually stacked to form a heat exchanger core, and finally reinforced with a metal frame, usually made of galvanized iron plate or stainless steel

This type of heat exchanger does not consume any electricity and does not actively convert heat between two types of air. Therefore, it must be install for use in air purification equipment or other heat recovery systems

Advantages of Air To Air Heat Exchanger

• Lightweight design

The raw material of this heat exchanger is 90% plain aluminum foil, with a thickness of only 0.1mm. A large heat exchanger with dimensions of 800 * 800 * 1200mm weighs less than 49kg. This lightweight design is beneficial for installation and cost control

• Efficient heat transfer capability

Due to the high plasticity of aluminum foil material, each aluminum foil has many small waves. When the airflow passes through these small waves, it will fully contact the aluminum foil and quickly transfer heat, achieving efficient heat transfer efficiency,

• Compatible with both cooling and heating environments

Because this air to air heat exchanger has two independent channels, the two types of air do not mix or cross or flow, making it perfectly compatible with cooling and heating environments, and can be quickly switched without additional costs

• Long term service life

The heat exchanger frame is stainless steel material, and its overall structure is very sturdy. It does not require any maintenance or additional costs during use, and there is no need to worry about its service life. In theory, it can be uses continuously without a scrap period

Production process of air-to-air heat exchanger

Aluminum foil compression molding

Aluminum foil is press by a special stamping machine to form a unique pattern, which adopts scientific design. When two aluminum foils are stacking, a channel with a height of 5-10mm is form in the middle, and the airflow will flow from the middle of this channel,

An automat device produces these aluminum foils, which are install on feeding machines. Stamping machines press the desired pattern, and a moving device moves the aluminum foil according to the set length. Finally, the cutting device cuts the excess material and cuts the required length No workers are required to participate in this production process. You can check the video below to learn about this production process

Aluminum foil stacking

This process requires the participation of workers to stack aluminum foil according to the design requirements to form a complete heat exchanger core. Usually, aluminum foil is cross stacking to give the heat exchanger two independent channels, so that the two types of air will not cross mix at any time

Installation Framework

When the core assembly of the heat exchanger is completion, it is necessary to install a frame to reinforce it. The installation frame needs to place glass glue on the inside of the column because the corner position of the core needs to be sealed. Finally, the column and metal plate are connected by rivets. At this point, a complete air to air heat exchanger is manufactured

Our services

1. We manufacture this heat exchanger according to your size requirements, including the pitch size of the aluminum foil, the length and width size of the aluminum foil, and the height size of the core. We accept a minimum size of 200mm and a maximum size of 1200mm. If you accept the splicing size, the maximum size of our heat exchanger is 2200 * 2200mm

2. If you have your own brand, we accept placing your brand logo in the most prominent position of the heat exchanger, which can be laser printed or sticker printed, but you need to authorize your brand to be produced in our factory

3. We offer customized services for air to air heat exchangers made of different materials. Currently, we accept customized services for stainless steel, aluminum, and copper materials. The connection of stainless steel materials is using welding technology, which incurs higher manufacturing costs

4. We have cooperative relationships with globally renowned shipping companies for sea transportation services. No matter which country you are in, we can deliver heat exchangers to your factory at a much lower shipping cost than our competitors
