Peltier Cooler Efficiency
H height of the thermoelectric element in millimeters.
Peltier cooler efficiency. тв product abbreviation thermoelectric battery cooler. Such an instrument is also called a. с length of the rib of the thermoelectric element basis in millimeters. The following video shows taking the peltier module from the above water dispenser and doing this peltier cooling efficiency test.
Cui devices line of high performance thermoelectric modules delivers superior cooling performance and a longer cycle life with its innovative arctec structure ranging in size from 20 mm to 50 mm with profiles as low as 3 15 mm these peltier modules are available with a δtmax up to 95 c th 50 c and current ratings from 2 0 a to 12 5 a. For example in the module tb 161 1 4 1 5. It has the additonal feature of showing a little water being turned to ice while sitting on the peltier module for just a few minutes. N number of thermocouples in the cooler.
Tec controllers are used for thermoelectric cooling and heating in combination with peltier elements. All three points are discussed in this article. Thermoelectric cooling uses the peltier effect to create a heat flux at the junction of two different types of materials. Peltier modules efficiency heavily depends on the temperature differential.
With the doubled heat flow of the second case the efficiency might be 85. Avoid it if possible. The efficiency of a peltier element application depends on the coefficient of performance cop which depends on the operating point the thermal design and the tec controller supply type. If you try to make both sides too different in temperature the cop will reach zero meaning your peltier is wasting electricity and outputting heat without actually doing work i e.
An universal abbreviation is used to notate single stage coolers. For example most peltier modules can handle up to 50ºc dt more or less. Video peltier module cooling the peltier effect. Running peltier devices at near their rated power is very inefficient and requires a lot of care to prevent thermal runaway and device destruction.
In this episode we discuss peltier coefficient of performance efficiency this video series was made in response to the many youtube tec peltier efficiency.
