Abstract

Claims (10)

1. A two-way heat exchanger for transferring heat from a first liquid to a second liquid, comprising:

a plurality of plate assemblies in a generally parallel stacked arrangement defining a plurality of channels, each between adjacent plate assemblies, said channels alternating between first and second channels for separate flow therethrough of the first and second liquids, respectively,

wherein each plate assembly comprises a plastic support plate having a thickness of about 0.4 mm utilizing a mesh turbulator for turbulating the first liquid or the second liquid flowing through a channel defined by said support plate and another support plate on an opposite side of the mesh turbulator in an adjacent plate assembly, said mesh turbulator setting a distance between said support plate and said another support plate by structurally separating said support plate and said another support plate, wherein each plate assembly also includes an inlet opening for flow of the first liquid or the second liquid into said channel, an outlet opening for discharging the first liquid or the second liquid from said channel, and a seal structure for allowing passage of only one of said first and second liquids through said channel.

2. The two-way heat exchanger of claim 1 , wherein the mesh turbulator in each plate assembly is molded in the support plate.

3. The two-way heat exchanger of claim 1 , wherein the mesh turbulator in each plate assembly is a separate component from the support plate.

4. The two-way heat exchanger of claim 1 , wherein the mesh turbulator in each plate assembly comprises a diamond mesh turbulator.

5. The two-way heat exchanger of claim 1 , wherein the mesh turbulator in each plate assembly comprises a plastic netting material.

6. The two-way heat exchanger of claim 1 , wherein each support plate comprises a thermally conductive rigid plastic material or a fiberglass-reinforced plastic material.

7. The two-way heat exchanger of claim 1 , further comprising outer covers at opposite ends of the plurality of plate assemblies.

8. The two-way heat exchanger of claim 1 , wherein the first and second liquids flow in generally opposite directions in adjacent channels.
