Microchannel heat exchanger – specialized equipment used in refrigeration and climatic systems and designed for rapid dissipation of thermal energy. In essence, it is a set of corrugated plates, in the normal state, pressed against each other.
Compared to the traditional exchanger
Microchannel heat exchangers have significant advantages over traditional heat exchangers. They are stronger, more compact, and, with a smaller internal volume (up to 77% less than in classic maintenance), have higher efficiency. All this is achieved due to the following design features of the heat exchanger:
- it consists of plates with microchannels (i.e., with a large total area of the inner surface), to which specially-shaped fins are attached by soldering;
- manifolds with dividing baffles ensure the most efficient distribution of the refrigerant through the microchannels;
- the heat exchanger is completely made of aluminum.
There is no risk of galvanic corrosion in microchannel heat exchangers. An additional advantage is the ability to change the geometry of the heat exchanger. Only a microchannel heat exchanger manufacturer provides the device able to withstand the stresses and harsh environments found in automotive air conditioners.
Peculiarities of microchannel type
In approaches of microchannel type, it is critical that the heat exchanger is planned and made to endure the impact of flooding by condensate. If not, the presence of condensate in the hotness exchanger will influence execution and impact the existence of the unit.
If the system is appropriately planned, this strategy for guideline can enjoy specific benefits. One of them is that the condensate is cooled somewhat comparative with the consolidating temperature prior to leaving the heat exchanger. This essentially decreases how many glimmers steam is produced in the condensate pipe downstream of the condensate channel. Thus, this prompts a decline in heat misfortunes and an improvement in the activity of the whole condensate procedure.
