  • microchannel cooled Heatsinks for high average power laser diode arrays
    Proceedings of SPIE, 1993
    Co-Authors: William J Benett, Raymond J Beach, B L Freitas, M A Emanuel, Dino R Ciarlo, Steven B Sutton, R Solarz
    Abstract:

    Detailed performance results and fabrication techniques for an efficient and low thermal impedance laser diode array heatsink are presented. High duty factor or even CW operation of fully filled laser diode arrays is enabled at high average power. Low thermal impedance is achieved using a liquid coolant and laminar flow through microchannels. The microchannels are fabricated in silicon using a photolithographic pattern definition procedure followed by anisotropic chemical etching. A modular rack-and-stack architecture is adopted for the heatsink design allowing arbitrarily large two-dimensional arrays to be fabricated and easily maintained. The excellent thermal control of the microchannel cooled Heatsinks is ideally suited to pump array requirements for high average power crystalline lasers because of the stringent temperature demands that result from coupling the diode light to several nanometers wide absorption features characteristic of lasing ions in crystals.

  • Penambahan Sistem Pendingin Heatsink Untuk Optimasi Penggunaan Reflektor Pada Panel Surya
    'Perpustakaan Universitas Andalas', 2019
    Co-Authors: Andi Pawawoi, Zulfahmi Zulfahmi
    Abstract:

    An alternative to increase photovoltaic output power is by increasing the intensity of received light using a reflector. However, the added intensity will increase in the temperature, hence reduce the photovoltaic output power. To optimize the use of reflectors in photovoltaics, a cooling system (i.e. Heatsink) needs to be added. This paper aims to find out the effect of adding a Heatsink cooling system to photovoltaics that equipped with a reflector. Heatsinks are installed at the entire back side of the panel and filled with thermal paste. Observations were made by comparing the photovoltaic system using a reflector without cooling system and the photovoltaic system using a reflector equipped with a Heatsink cooling system. The results show that the photovoltaic with cooling system has 18.26% average temperature decrease and 10.14% average power increase if compared to a photovoltaic system equipped with a reflector without a cooling system

However, the added intensity will increase in the temperature, hence reduce the photovoltaic output power. To optimize the use of reflectors in photovoltaics, a cooling system (i.e. Heatsink) needs to be added. This paper aims to find out the effect of adding a Heatsink cooling system to photovoltaics that equipped with a reflector. Heatsinks are installed at the entire back side of the panel and filled with thermal paste. Observations were made by comparing the photovoltaic system using a reflector without cooling system and the photovoltaic system using a reflector equipped with a Heatsink cooling system. The results show that the photovoltaic with cooling system has 18.26% average temperature decrease and 10.14% average power increase if compared to a photovoltaic system equipped with a reflector without a cooling system. Keywords: Photovoltaic, temperature, power, and cooling system.Abstrak Alternatif yang dapat dipilih untuk meningkatkan daya keluaran photovoltaik yakni dengan menambah intensitas cahaya yang diterima menggunakan reflektor. Namun apabila intensitas ditambah akan menyebabkan kenaikan temperatur yang ikut seiring dengan peningkatan intensitas cahaya, hal ini akan menurunkan daya keluaran photovoltaik. Untuk mengoptimalkan penggunaan reflektor pada photovoltaik perlu ditambahkan sistem pendingin. Tulisan ini bertujuan untuk melihat pengaruh penambahan sistem pendingin Heatsink pada photovoltaik yang dilengkapi dengan reflektor. Heatsink ditempelkan pada seluruh sisi belakang panel, dan untuk memperkecil resistansi termal, maka antara panel dan Heatsink diisi dengan paste termal. Pengamatan dilakukan dengan membandingkan 2 sistem, yaitu: sistem photovoltaik menggunakan reflektor tanpa pendingin dan sistem photovoltaik menggunakan reflektor yang dilengkapi sistem pendingin Heatsink. Hasilnya menunjukkan bahwa bahwa dengan penambahan sistem pendingin  photovoltaik yang dilengkapi reflektor diperoleh penurunan suhu rata-rata 18,26% dan peningkatan daya rata-rata sebesar 10,14% dibanding sistem  photovoltaik yang dilengkapi reflektor tanpa sistem pendingin. Kata kunci: Photovoltaik, temperatur, daya, dan sistem pendingin
