Abstract
Abstract An active intercooler for heating or cooling a fluid passing through the intercooler. The intercooler may be used to cool gases from the compression stage of an engine turbocharger in order to increase engine horsepower. The intercooler could also be used to cool the oil in an engine or transmission. Alternately, the intercooler could be used to heat or cool the air provided to the passenger compartment of a vehicle. The active intercooler includes a chamber through which the fluid flows. A thermoelectric heat pump is attached to the chamber in order to remove and dissipate heat from the fluid flowing through the chamber. A control system is provided to control the current supplied to the thermoelectric heat pump and thus the cooling capacity of the thermoelectric heat pump. A heat sink including a plurality of fins is attached to the thermoelectric heat pump on a surface opposite the chamber in order to increase the ability of the thermoelectric heat pump to dissipate heat.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
An active intercooler for heating or cooling the gazes exiting a compression stage of a turbocharger, the intercooler comprising: a chamber for receiving the gases exiting the compression stage of the turbocharger, the interior of the chamber having a plurality of tubes through which the gases flow, and an antifreeze filling the chamber and surrounding the tubes; a thermoelectric heat pump thermally coupled to the chamber; and temperature control means for controlling the current flow through the thermoelectric heat pump to control the temperature of the chamber and, thus, the temperature of the gases flowing through the chamber.
Claim 2
Dependent Claim
98 words
An active intercooler for heating or cooling the gazes exiting a compression stage of a turbocharger, the intercooler comprising: a chamber for receiving the gases exiting the compression stage of the turbocharger, the interior of the chamber having a plurality of tubes through which the gases flow, and an antifreeze filling the chamber and surrounding the tubes; a thermoelectric heat pump thermally coupled to the chamber; and temperature control means for controlling the current flow through the thermoelectric heat pump to control the temperature of the chamber and, thus, the temperature of the gases flowing through the chamber.
Claim 3
Dependent Claim
27 words
The intercooler of claim 1, further including a heat sink having a plurality of fins attached to a side of the thermoelectric heat pump opposite the chamber.
Claim 4
Dependent Claim
114 words
An intercooler used to cool the gases exiting a compression stage of a turbocharger before the gases are provided to an engine, the intercooler comprising: a chamber connected to said compression stage of said turbocharger so that the gases from said compression stage of said turbocharger flow through the chamber, the chamber including a plurality of tubes through which the gases flow and the interior of the chamber surrounding said tubes being filled with an antifreeze; a thermoelectric heat pump attached to the side of the chamber; and means for controlling the current flow through the thermoelectric heat pump to control the rate of heat removed from the gases and dissipated by the intercooler.
Claim 5
Dependent Claim
114 words
An intercooler used to cool the gases exiting a compression stage of a turbocharger before the gases are provided to an engine, the intercooler comprising: a chamber connected to said compression stage of said turbocharger so that the gases from said compression stage of said turbocharger flow through the chamber, the chamber including a plurality of tubes through which the gases flow and the interior of the chamber surrounding said tubes being filled with an antifreeze; a thermoelectric heat pump attached to the side of the chamber; and means for controlling the current flow through the thermoelectric heat pump to control the rate of heat removed from the gases and dissipated by the intercooler.
Claim 6
Dependent Claim
21 words
The intercooler of claim 3, further comprising a heat sink including a plurality of fins attached to the thermoelectric heat pump.
Claim 7
Dependent Claim
129 words
An intercooler for cooling a fluid passing through the intercooler, the intercooler comprising: a chamber having an interior and an exterior, the interior of the chamber including a plurality of tubes that are in fluid connection with a compression stage of a turbocharger, the gases from the compression stage of the turbocharger flowing through the tubes prior to being provided to an engine, wherein the interior of the chamber surrounding the tubes is filled with an antifreeze; a thermoelectric heat pump attached to at least one side of the chamber; and control means for controlling the current supplied to the thermoelectric heat pump to control the temperature of the gases flowing through the chamber by controlling the rate of heat transfer between the chamber and the thermoelectric heat pump.
Claim 8
Dependent Claim
129 words
An intercooler for cooling a fluid passing through the intercooler, the intercooler comprising: a chamber having an interior and an exterior, the interior of the chamber including a plurality of tubes that are in fluid connection with a compression stage of a turbocharger, the gases from the compression stage of the turbocharger flowing through the tubes prior to being provided to an engine, wherein the interior of the chamber surrounding the tubes is filled with an antifreeze; a thermoelectric heat pump attached to at least one side of the chamber; and control means for controlling the current supplied to the thermoelectric heat pump to control the temperature of the gases flowing through the chamber by controlling the rate of heat transfer between the chamber and the thermoelectric heat pump.
Claim 9
Dependent Claim
27 words
The intercooler of claim 5, further comprising a heat sink including a plurality of fins attached to a side of the thermoelectric heat pump opposite the chamber.
Claim 10
Dependent Claim
50 words
The intercooler of claim 5, further including an inlet attached to the chamber in order to allow the gases to flow into one end of the tubes and an outlet attached to the other end of the tubes so as to allow the gases to flow out of the chamber.
