🔷 Basic Performance Spec

🔷 Additional Performance Spec

In addition to the basic specifications, engineers should evaluate the electrical and thermal characteristics of the thermoelectric cooler.

Important considerations include electrical resistance, thermal conductivity, cooling performance under different operating conditions, hot-side heat dissipation, and temperature stability.

For customized applications, the required cooling load and ambient temperature should be confirmed before selecting the appropriate module. These factors help determine whether a compact thermoelectric cooler can meet the system's actual requirements.

🔷 Performance Curve

🔷 Product Overview

The 15×15×3.5mm Thermoelectric Cooler is designed for compact thermal management applications that require a small-format cooling component. Its miniature dimensions make it suitable for evaluation in space-constrained electronic assemblies and precision temperature-control systems, subject to its verified performance specifications.

For product developers, selecting the right thermoelectric module involves more than comparing dimensions. Electrical input, cooling load, temperature difference, mounting conditions, and heat dissipation all influence the final result.

KKG provides product selection support for customers evaluating thermoelectric cooling solutions. For OEM projects, customers can share their target temperature, available installation space, power supply, and expected cooling load to help determine a suitable configuration.

🔷 Product Features

• Compact Dimensions: The 15×15×3.5mm format is suitable for evaluating space-constrained designs.
• Solid-State Cooling Technology: Thermoelectric cooling operates without conventional refrigerant circulation.
• Flexible System Integration: Can be evaluated for integration into compatible electronic and thermal management assemblies.
• Application-Specific Selection: Electrical and cooling parameters can be assessed against actual project requirements.
• OEM Project Support: Technical requirements can be reviewed for customized product development.
• Bulk Purchasing Options: Supply arrangements can be discussed for qualifying production and procurement projects.

Note: Final performance, reliability, and customization capabilities should be confirmed against the actual product specification and manufacturing options.

🔷 Product Applications

Depending on its verified electrical and thermal performance, a miniature thermoelectric cooler may be evaluated for applications such as:

• Miniature electronic cooling devices.
• Compact temperature-control assemblies.
• Small optical and sensor modules.
• Laboratory instruments and analytical equipment.
• Localized cooling for electronic components.
• Portable temperature-control devices.
• Precision thermal management prototypes.
• OEM electronic equipment requiring compact cooling components.

The suitability of this 15×15×3.5mm model depends on the required cooling capacity, operating temperature, heat load, and available heat dissipation structure.

🔷 Product Structure

🔷 Operation Principle / Work Principle

A thermoelectric cooler works through the Peltier effect. When direct current flows through the thermoelectric elements, heat is absorbed at one side and released at the other side.

To achieve effective cooling, the cold side must be thermally connected to the target component, while the hot side must be connected to a suitable heat dissipation structure.

If the hot side cannot release heat efficiently, the temperature of the module may rise and cooling performance may decline. Therefore, correct installation, thermal interface materials, power control, and heat sink selection are important parts of system design.

🔷 Product Testing

Product testing helps verify whether a thermoelectric cooler meets the required specifications and application conditions.

Depending on the agreed inspection plan, relevant checks may include:

• Dimensional inspection.
• Electrical resistance measurement.
• Voltage and current verification.
• Cooling performance testing under specified conditions.
• Visual inspection of ceramic surfaces and lead wires.
• Appearance and packaging inspection.

Test methods, acceptance criteria, and inspection reports should be confirmed with the supplier before ordering. Specific test results should only be published when supported by actual inspection records.

🔷 Product Packaging

Thermoelectric coolers contain ceramic substrates and internal components that require appropriate handling during storage and transportation.

Packaging should help prevent impact, surface damage, contamination, and lead-wire deformation. For bulk shipments and OEM orders, packaging requirements can be discussed according to order quantity, transport method, and customer handling needs.

Please confirm the available packaging format, minimum order quantity, labeling requirements, and export packaging arrangements before placing an order.

🔷FAQ

Q1: What is a 15×15×3.5mm thermoelectric cooler used for?

It can be evaluated for compact cooling and localized temperature-control applications. The final application depends on its verified cooling capacity, electrical characteristics, and operating temperature range.

Q2: How do I select the right thermoelectric cooler for my project?

Start by confirming the target temperature, cooling load, available installation space, power supply, and heat dissipation conditions. These details help engineers assess whether the module is suitable for the application.

Q3: Does KKG support OEM thermoelectric cooler projects?

OEM requirements can be discussed based on the project's technical specifications, expected quantity, and customization needs. Please provide the application details for evaluation.

Q4: Can I order thermoelectric coolers in bulk?

Bulk purchasing requirements can be discussed with the supplier. Order quantity, production lead time, packaging, and delivery arrangements should be confirmed before placing an order.

Q5: Can I request a custom thermoelectric cooling module?

Custom requirements should be evaluated according to the required dimensions, electrical parameters, thermal performance, lead wires, and assembly structure. Feasibility depends on the manufacturer's capabilities and the project specifications.

Q6: What information is needed for a quotation?

Please provide the required dimensions, target voltage and current, expected cooling capacity, operating temperature, application description, estimated order quantity, and any drawing or reference sample available.

Q7: Is a thermoelectric cooler the same as a thermoelectric generator?

No. A thermoelectric cooler uses electrical energy to transfer heat, while a thermoelectric generator converts a temperature difference into electrical energy. The appropriate product category depends on the intended function.
