Definitions
- thermoelectric devices relate to thermoelectric devices and their operation.
- Thermoelectric devices are solid state semiconductor devices that, depending on the particular application, can be either Thermoelectric Coolers (TECs) or Thermoelectric Generators (TEGs). TECs are solid state
- thermoelectric devices that utilize the Peltier effect to transfer heat from one side of the device to the other, thereby creating a cooling effect on the cold side of the device. Because the direction of heat transfer is determined by the polarity of an applied voltage, thermoelectric devices can be used generally as temperature controllers. Similarly, TEGs are solid state semiconductor devices that utilize the Seebeck effect to convert heat (i.e., a temperature difference from one side of the device to the other) directly into electrical energy.
- a thermoelectric device includes at least one N-type leg and at least one P-type leg. The N-type legs and the P-type legs are formed of a thermoelectric material (i.e., a semiconductor material having sufficiently strong thermoelectric properties). In order to effect thermoelectric cooling, an electrical current is applied to the thermoelectric device.
- thermoelectric devices The direction of current transference in the N-type legs and the P-type legs is parallel to the direction of heat transference in the thermoelectric device. As a result, cooling occurs at the top surface of the thermoelectric device, and the heat is released at the bottom surface of the thermoelectric device.

- FIG. 1 illustrates a thermoelectric refrigeration system 10 having a cooling chamber 12, a heat exchanger 14 including at least one Thermoelectric Module (TEM) 22 (referred to herein singularly as TEM 22 or plural as TEMs 22) disposed between a cold side heat sink 20 and a hot side heat sink 18, and a controller 16 that controls the TEM 22 according to some embodiments of the present disclosure.

- FIG. 1 illustrates a thermoelectric refrigeration system 10 having a cooling chamber 12, a heat exchanger 14 including at least one Thermoelectric Module (TEM) 22 (referred to herein singularly as TEM 22 or plural as TEMs 22) disposed between a cold side heat sink 20 and a hot side heat sink 18, and a controller 16 that controls the TEM 22 according to some embodiments of the present disclosure.
- TEM 22 Thermoelectric Module
- Thermoelectric Cooler (TEC) 22 Thermoelectric Cooler 22.
- the TEMs 22 are preferably thin film devices. When one or more of the TEMs 22 are activated by the controller 16, the activated TEMs 22 operate to heat the hot side heat sink 18 and cool the cold side heat sink 20 to thereby facilitate heat transfer to extract heat from the cooling chamber 12. More specifically, when one or more of the TEMs 22 are activated, the hot side heat sink 18 is heated to thereby create an evaporator and the cold side heat sink 20 is cooled to thereby create a condenser, according to some embodiments of the current disclosure.
- the cold side heat sink 20 facilitates heat extraction from the cooling chamber 12 via an accept loop 24 coupled with the cold side heat sink 20.
- the accept loop 24 is thermally coupled to an interior wall 26 of the thermoelectric refrigeration system 10.
- the interior wall 26 defines the cooling chamber 12.
- the accept loop 24 is either integrated into the interior wall 26 or integrated directly onto the surface of the interior wall 26.
- the accept loop 24 is formed by any type of plumbing that allows for a cooling medium (e.g., a two-phase coolant) to flow or pass through the accept loop 24. Due to the thermal coupling of the accept loop 24 and the interior wall 26, the cooling medium extracts heat from the cooling chamber 12 as the cooling medium flows through the accept loop 24.
- the accept loop 24 may be formed of, for example, copper tubing, plastic tubing, stainless steel tubing, aluminum tubing, or the like.
- the hot side heat sink 18 facilitates rejection of heat to an environment external to the cooling chamber 12 via a reject loop 28 coupled to the hot side heat sink 18.
- the reject loop 28 is thermally coupled to an outer wall 30, or outer skin, of the thermoelectric refrigeration system 10.
- thermoelectric refrigeration system 10 shown in Figure 1 is only a particular embodiment of a use and control of a TEM 22. All embodiments discussed herein should be understood to apply to thermoelectric refrigeration system 10 as well as any other use of a TEM 22.
- the controller 16 operates to control the TEMs 22 in order to maintain a desired set point temperature within the cooling chamber 12.

- the controller 16 is enabled to separately or
- the controller 16 may be enabled to separately control a first individual TEM 22, a second individual TEM 22, and a group of two TEMs 22.
- the controller 16 can, for example, selectively activate one, two, three, or four TEMs 22 independently, at maximized efficiency, as demand dictates.

- FIGS 2A-2C illustrate an architecture for driving multiple channels of a device in parallel.
- An Alternating Current (AC) or Direct Current (DC) offline power supply 32 outputs power to a DC to DC converter 34 which then provides power to a device 36.
- the device 36 contains two channels that are being powered in parallel.
- This DC to DC converter 34 may be bulky or expensive.
- Figure 2A shows an example where the DC to DC converter 34 can provide a variable DC voltage to power the device 36. This type of variability may be expensive and difficult to tune for efficiency.
- FIGS 2B and 2C show examples of Pulse Width Modulation (PWM) being used to provide the desired amount of power to the device 36. Since PWM typically switches between some high value and some low (e.g., zero) value, the actual efficiency of the device 36 is determined by that high value and low value and not the average amount of power provided. This can lead to less efficient power levels and heat leakback during the off periods.
- PWM Pulse Width Modulation
- Figures 3A-3C illustrate an architecture for driving multiple channels of a device in series.
- an AC or DC offline power supply 32 outputs power to a DC to DC converter 34 which then provides power to the device 36.
- the device 36 contains two channels that are being powered in series. Again, this DC to DC converter 34 may be bulky or expensive.
- Figure 3A shows an example where the DC to DC converter 34 can provide a variable DC voltage to power the device 36. This type of variability may be expensive and difficult to tune for efficiency.
- Figures 3B and 3C show examples of PWM being used to provide the desired amount of power to the device 36.
- PWM typically switches between some high value and some low (e.g., zero) value
- the actual efficiency of the device 36 is determined by that high value and low value and not the average amount of power provided. This can lead to less efficient power levels and heat leakback during the off periods.
- Thermoelectric devices in cooling applications are operated using DC voltage. To vary the heat pumping, this DC voltage level is increased, decreased, or PWM. Varying the voltage level requires access to the associated power regulator's control loop which may introduce potential instabilities and complexities, or adding secondary DC to DC regulator(s) to the bulk voltage. PWM does not allow for operation of the thermoelectric device at both the maximum Coefficient of Performance (COP) and maximum Q points of its operational curve (since the performance of the device depends on the instantaneous voltage applied to it).
- COP Coefficient of Performance

For instance, there could be any number of Channels and some could be connected in series while others are connected in parallel.
