Understanding Peltier Technology

Peltier elements are specialized heat pumps that utilize the Peltier effect to transfer heat from one side of the element to the other. This creates a temperature difference across the device, which can be harnessed for cooling or heating purposes. The Peltier effect is an electrothermal phenomenon that occurs when an electrical current is applied, making these elements capable of cooling and heating without the need for changing connectors or any mechanical alterations.

In practical applications, Peltier elements are driven by TEC controllers, which are essential for thermoelectric cooling and heating. These controllers can manage the direction and magnitude of the electric current flowing through the Peltier elements, effectively controlling the temperature of an object or space. The use of TEC controllers in tandem with Peltier elements allows for precise temperature control in a variety of applications, ranging from electronic devices to specialized equipment.

Offered as a type of service, Peltier technology involves designing thermoelectric cooling systems that incorporate TEC controllers, Peltier elements, and temperature sensing components such as Pt100 or Pt1000 sensors. The service may also include the use of a universal preassembled thermoelectric cooling assembly for rapid prototyping and testing. Peltier service is integral in applications where active cooling below ambient temperature is required, such as in complex thermal designs where companies like Elinter AG may provide expertise.

From a design perspective, Peltier elements are advantageous because of their small size, lack of moving parts, and the ability to configure them in various shapes, such as square or ring forms. They can be single-stage or multistage, with the latter being used for higher temperature differences. Peltier elements have a broad temperature range and can achieve a maximum cooling capacity of up to 290 W, depending on the specific type and configuration.

Peltier Plugins for Excel

Installation and Setup

Peltier plugins are provided as Excel Add-Ins which can be installed to open automatically with Excel or can be opened on an as-needed basis. These Add-Ins are typically distributed in a zip file and should be stored in a convenient location like the User Add-in Library, which is accessible via the %appdata% Run command. Before using the Add-Ins, they must be unblocked in Windows to function properly. Installation can be done from the Developer tab or through Excel Options.

Uninstalling Add-Ins

To uninstall a Peltier plugin, simply uncheck it from the Add-Ins list in the Excel Add-Ins dialog. This action removes the Add-In from being active within Excel but does not delete the actual Add-In file from the system.

Using Without Installation

Add-Ins, including Peltier plugins, can be used without installation by opening them directly. This allows you to use the Add-In's functionality for the current session without having it load automatically every time you start Excel. However, if an Add-In is blocked, it will not load and must be unblocked before it can be used.

Mac Installation Protocols

There are specific protocols for installing an Excel Add-In on a Mac, ensuring compatibility and functionality for Mac users. Following these instructions is essential for the plugins to work correctly on the macOS version of Excel.

Enhancing Excel Charting

Peltier plugins are particularly beneficial for creating and enhancing charts in Excel. They enable the creation of charts from arbitrary rectangular ranges, including pivot tables, and provide modular functions to streamline processes. These plugins can also significantly improve the visual presentation of charts, making them more professional and readable by applying uniform fonts, adjusting spacing, and reducing white space.

Frequently Asked Questions

How do I install the Peltier plugin for Excel on Windows?

To install the Peltier plugin on Windows, first unzip the PeltierTechCharts40.zip file to a new directory with read and write access, such as the User Add-In Library. Then, go to Excel's Options menu, access the Add-Ins option, and choose to install the add-in. Ensure that the User Add-In Library is a Trusted Location to avoid blocking issues.

What should I do if the Peltier plugin is blocked by Windows?

If Windows blocks the Peltier plugin, right-click the add-in file in the file explorer, select Properties, and then click the 'Unblock' button. After unblocking, you can proceed with the installation or opening of the add-in in Excel.

Can I use the Peltier plugin without installing it?

Yes, the Peltier plugin can be used without being installed by simply opening the add-in file in Excel.

How do I access the Peltier plugin features after installation?

Once installed, the Peltier plugin integrates into Excel, adding a custom tab to the Excel Ribbon for easy access to its enhanced charting capabilities and features.

What are the main benefits of using the Peltier plugin in Excel?

The Peltier plugin offers enhanced charting capabilities, such as improved versions of native Excel charts, better chart formatting and data editing capabilities, and simplifies the creation of complex charts. It also includes additional features like Loess Regression and Nice Table Styles, all accessible without the need for programming skills.
