摘要： A low-cost thermoelectric module utilizing a greatly reduced quantity of thermoelectric material as compared to similar prior art thermoelectric modules. An egg crate design containing thermoelectric elements is utilized in the present invention. However, the walls of the egg crate in the parts of the module separating the thermoelectric elements are made thick so that the total cross sectional area of the elements is less than 75 percent of the total module cross sectional area. The spaces above and below the elements are filled with a high heat and electric conducting material such as aluminum. This produces funnel-shaped conductors funneling heat and electric current into and out of each of the thermoelectric elements. The payoff to this approach is that the heat flux through the hot and cold module surfaces can be maintained while producing the same power output with about half the thermoelectric material or less. Avoiding any significant increase in heat flux through the module surface means avoiding increases in temperature drops normally encountered at the module surfaces.
摘要翻译：与类似的现有技术的热电模块相比，一种低成本的热电模块利用大量减少的热电材料。在本发明中使用含有热电元件的蛋箱设计。然而，在分离热电元件的模块的部分中的蛋箱壁被制成较厚的部件，使得元件的总截面积小于总模块横截面面积的75％。元件之上和之下的空间填充有高热导电材料，例如铝。这产生漏斗形导体将热和电流漏入和流出每个热电元件。这种方法的回报是通过热和冷模块表面的热通量可以被保持，同时产生具有大约一半的热电材料或更少的相同的功率输出。避免通过模块表面的热通量的任何显着增加意味着避免模块表面通常遇到的温度下降的增加。

摘要： A thermoelectric module having a gapless insulating eggcrate providing insulated spaces for a large number of p-type and n-type thermoelectric elements. The absence of gaps in the walls of the spaces virtually eliminates the possibility of interwall shorts between the elements. Electrical connections on both the hot and cold sides of the module electrically connect the elements in series or in parallel as desired. Usually, most or all of the elements will be connected in series. In a preferred embodiment, the gapless eggcrate is formed from a high temperature plastic. In a preferred embodiment, two lead wires are added before adding the hot and cold side electrical connections. In this embodiment, electrical connections on the hot and cold sides comprise a thin layer of molybdenum and a coating of aluminum over the molybdenum. The surfaces are ground down to expose the insulating eggcrate walls except where connections between the elements are desired. In this preferred embodiment a seal is then applied over both the hot and cold surfaces. The seal preferably is comprised of a very thin electrically insulating layer and over this electrically insulating layer a thin metal layer is provided.

摘要： A method for fabricating a thermoelectric module with thermoelectric elements installed in an gapless eggcrate. This gapless eggcrate provides insulated spaces for a large number of p-type and n-type thermoelectric elements. The absence of gaps in the walls of the spaces virtually eliminates the possibility of interwall shorts between the elements. Thermoelectric elements, both p-type and n-type, are inserted into the insulated spaces in the gapless eggcrate to provide the desired thermoelectric effects . Electrical connections are established on both the hot and cold sides of the module to connect the thermoelectric elements in series or parallel as desired. Normally, most or all of the elements will be connected in series. In a preferred embodiment the gapless eggcrate is formed from a high temperature plastic. P-type thermoelectric material is extruded and then sliced to form p-type thermoelectric elements, and n-type thermoelectric material is extruded and sliced to form n-type thermoelectric elements. The thermoelectric elements are loaded in the eggcrate in an arrangement to put them all in series when a metal spray is applied to the hot and cold sides. Two electrical leads are applied and electrical connections on both the hot and cold sides are provided using a metal thermal spray technique. A thin layer of molybdenum is sprayed on one of the surfaces and then a coating of aluminum is sprayed over the molybdenum. These steps are repeated for the other side. Then the surfaces are ground down to expose the insulating eggcrate walls except where connections between the elements are desired. A seal is then applied over both the hot and cold surfaces. The seal preferably is very thin electrically insulating layer and over this layer a layer of aluminum is provided.

摘要： A powder injection molding and infiltration process. A powder of a skeleton material having a relatively high melting point is mixed with a composite binder to form a mold mixture. The composite binder is comprised of at least two binder materials. The mold mixture is molded into a desired shape in a mold device to produce a molded part. The composite binder is then removed to produce voids in the molded part and the voids are filled by infiltrating an infiltrant comprised of an infiltrant material having a relatively low melting point to produce a composite molded part. In a preferred embodiment the skeleton material is TiB2 and the infiltrant material is aluminum and the composite binder is comprised of a plastic and a wax. In this embodiment the wax portion of the composite binder is removed using a solvent and the plastic is removed during the infiltration step. The resulting composite part has a TiB2 skeleton with voids substantially filled with aluminum. This process is especially useful for making light and strong parts with complex shapes such as golf club heads, tools, cutting implements, thermal management products, rocket motor components and bicycle parts. In another preferred embodiment, a golf club head is comprised of three parts: an non-sintered TiB2 part for the body of the head, a sintered TiB2 part for the striking surface of the head, and a heavy tungsten part to provide weight for the head. In this embodiment, the aluminum infiltrant substantially fills the voids in all three parts to create a golf club head with optimum characteristics.
