Device for transfer of heat

Abstract

A structure for housing electronic equipment, for example outdoor telecom applications such as radio base stations, in a climate-controlled environment. The structure comprises a compact climate-control unit adapted for integration into the structure. The climate system provides for circulation of air in an internal closed circuit for cooling of heat generated by the electronic units within a closed space within the interior of the structure.

Description

[0001] This application claims the benefit under 35 USC § 119(e) to Provisional application 60 / 708,770 filed 17 Aug. 2005 and Provisional application 60 / 709,133 filed 18 Aug. 2005.BACKGROUND Field of the invention [0002] The present invention relates to a simplified structure for preferably outdoor telecom applications, e.g. radio base stations. The simplified structure comprises a compact climate system adapted for integration into a fundamental structure for electronics. BACKGROUND [0003] As will be obvious for a man skilled in the art, the climate system has as a function to transport heat from the inner space of the outdoor cabinet to the outdoor ambient. It need not only be meant for cooling of electronic equipment but all kinds of heat exchange are conceivable. [0004] The invention is a further development of the device described in WO 92 / 18821, the teachings of which are hereby incorporated by reference. [0005] The conventional structures of today for outdoor cabinets for tel...

AI Technical Summary

Benefits of technology

"The present invention aims to solve the problem of overheating in outdoor cabinets containing electronic equipment. This is achieved by integrating a climate unit into the support structure of the electronics, or placing the climate unit in rack systems with the electronic units. The climate unit provides a closed circulation of air cooling to the electronics, or transfers air from the electronics to the climate unit. The invention also includes a climate system for outdoor cabinets that connects to the top of the cabinet, with a compartment containing the climate unit. The system has openings for air inflow and outflow, and is designed to efficiently cool the electronic equipment."

Problems solved by technology

This requirement of accessibility implies distinct limitations as to integrating the climate plant with the electronics.

This leads to a reduction in cooling efficiency and increases the temperature of the air intended for the cooling of the electronics.

A temperature increase of air intended for cooling may lead reduction of functions, breakdown in production or damages of the electronics.

To avoid this reduction in heat exchange efficiency some systems are equipped with connecting parts between the electronics and the climate system, and the risk for leakage between the parts is increased.

These type of systems are complicated with a lot of tubing, and leakage in these cases will lead to the above mentioned problems.

These types of systems with several parts located in different ways on different portions in the cabinet, which parts simultaneously have to be connected and function correctly together, become very voluminous, require a lot of mechanic parts, are difficult to standardize, require specific adaptation and are expensive.
