Cu gandul la spatiul limitat din cutie, am inceput sa ma uit dupa solutii de racire.

Am gasit un radiator care ar putea fi prelucrat sa incapa perfect (trebuie taiate doua aripioare laterale cam cate 13 mm ca sa incapa plus subtiate ca sa culiseze (au 3 mm, trebuie sa culiseze in canale de 2 mm).

Apoi m-am uitat de ventilatoare.
Un 120 mm ar avea nevoie de taiere in rama pentru a incapea, si nici atunci nu sunt sigur.
Apoi m-am uitat ca majoritatea ventilatoarelor sunt destul de groase. Ori gasesc unul frameless si tai la CNC in radiator locul pentru el, ori folosesc unul slim si-i crestez frame-ul.

Am comandat doua ventilatoare ca sa vad cam cum se potrivesc:

Cutia are 47.5 mm, din care 22.5 mm sunt folositi de radiator si 12-15 mm sunt folositi de ventilator.
Raman 13-10 mm pentru led-uri si cablaraie.

Am gasit pasta termoconductoare pe care pot sa o pun pe canalele pe care culisez radiatorul pentru a optimiza transferul termic.

Am mai descoperit si cutia aceasta, o tin in optiuni daca ventilatorul cel mai mare care incape nu face fata la caldura disipata:

Tocmai am realizat ca modalitatea de optimizare a spatiului pentru LEDuri si cablaraie este sa renunt la LEDuri lipite pe placute stea de 20 mm si sa fac un PCB cu conexiunile intre leduri, plasat pe o placuta de aluminiu, care sa culiseze perfect in cutie.

Dupa ce ma lamuresc cum fac canalele si cum asez ledurile si verific racirea, probabil acesta ar fi varianta cea mai eleganta. Are careva idee cum se poate realiza, sau trebuie sa dau comanda la o firma specializata? Sau e prea complicat si nu merita?

Ei au reusit sa puna 52 de LEDuri in 30.2x13.7x4 cm, dar jumatate din cutie este radiatorul cu ventilatorul incorporat. Probabil ca jumatatea cu LEDuri este impermeabila si are de asemenea un radiator de aluminiu pe care sunt montate LEDurile.

Azi mi-au venit cablurile pentru lipit LEDurile intre ele si LEDurile pentru doua canale de 10, un canal de CREE XT-E cool white si unul de CREE XP-E2 blue.

Avandu-le in mana, parca incepe sa devina plauzibil proiectul.
De cum imi vin controllerele incep sa ma joc.

Mai am nevoie de un transformator, inca nu m-am lamurit daca iau de 12V sau de 24V, probabil voi sfarsi prin a comanda cate unul din fiecare. Nevasta a priceput in sfarsit pe ce cheltuiam banii, pare mai relaxata si putin amuzata. Probabil se temea sa nu mai apara un acvariu in casa. ... nu inca.

Am hotarat ca voi lipi LEDurile in serie, vor fi cinci canale:
- blue x10
- cool white x10
- royal blue x10
- cool white x10
- blue x10

In benzile de cool white voi strecura si cateva LEDuri rosii si UV/near UV.

Sper sa pot lipi LEDurile cu asa ceva. Sfaturi, sugestii, pareri?

Voi avea nevoie de o placa de aluminiu 220x120.5x2mm care sa intre pe prima sina de sub suruburi, pe care sa fixez LEDurile fizic. Aceasta va fi in contact direct cu radiatorul pe toata suprafata.

De ce te complici?
1. gaseste un radiator care sa intre in cutie fara sa culiseze. De radiator prinzi led-urile si in laterale prinzi doua fasii de tabla de aluminiu de 2mm care sa intre in fantele laterale.
2. idem sus radiator care sa intre in cutie fara sa culiseze. De el prinzi si ventilatoarele si tot ansamblul il prinzi de fundul cutiei prin niste distantieri (teava + surub lung)
3. idem sus radiator care sa intre in cutie liber. De laterale prinzi niste suporti care pe care pui si prinzi radiatorul

Multumesc de raspuns.
Ma complic pentru ca:
- nu am experienta la lucrul manual
- sunt obsesiv- compulsiv
- lucrurile simple mi se par complicate
- iar cele complicate, mai simple

Una peste alta, inainte de cum asez lucrurile in cutie, trebuie sa ma dumiresc cum imi fac schema electrica. Deocamdata astept sa-mi vina controllerele ca sa vad cum ma lumineaza documentatia tehnica. Am insa o banuiala ca rezistenta pe care am vazut-o era legata cu ventilatorul, nu la LEDuri.

Parerea mea este ca varianta 2 data de mine este varianta cea mai buna. Pui led-urile, faci legaturile electrice inclusiv ventilatorul. bagi ansamblul in cutie il fixezi, bagi capacul culisabil si gata... Poti sa faci si testele in afara cutiei cu ventilatorul montat.
Solutia cu pcb de aluminiu este profi dar unde gasesti sa ti-l faca la preturi bune. oricum si acea placa trebuie prinsa de un radiator. Pe placa poti sa faci inclusiv circuitul de alimentare led-uri in curent constant... E fata morgana, sirena marinarilor

Salut,

Bafta si spor la lucru cu noul proiect.

Este mai lat dar il poti taia.
Ar fi bine daca ai vorbi cu Shubi, stiu ca are CNC si a mai facut chestii dastea- sa iti taie la dimensiuni si sa iti dea gaurile pentru fixat ledurile.


Si pentru partea de leduri - volti per seria

Iti mai trebuie si niste LDD-uri

Sper sa te ajute informatiile.

Este posibil ca LDDurile sa fie deja in controller?

Am gasit un loc unde pentru 100€ imi pot face PCBul.

IMS PCB PROTOTYPES WITH ALUMINIUM CORE

The abbreviation IMS stands for Insulated Metal Substrates. With IMS printed circuit boards instead of the usual base material, aluminium is used as the carrier for copper. 

Aluminium core printed circuit boards are used for the thermal management of the circuit. High power LEDs are the most well-known example of it. In addition, parts for controls, power transducers etc. are often developed with IMS PCBs. 

Presently we offer aluminum core printed circuit boards with the following technology in the IMS POOL:

1.5 mm thicknessIsolation layer: 100µmCopper: 35 µm Cu singlesided

Calculate the cost of your personal IMS prototype easily online using the following link. 

SOLDERMASK & SILKSCREEN

Depending on whether light is to be absorbed or reflected, you can select between black or white soldermask 

Silkscreen colours of black and white are available in the aluminium core PCB-POOL® service.

We charge a flat-rate fee when a solder mask is applied to single-sided circuit boards. This fee is independent of the circuit board size.

We charge a flat-rate fee when a silk screen is applied to circuit boards. This fee is independent of the circuit board size.



MECHANICAL PROCESSING

Would you like to mount your IMS (Insulated Metallic Substrate) PCB? No problem! 

For an optional extra charge it is possible to integrate threads, counter-sunk drills and depth milling. Such data must be delivered separately and is only accepted by us in DXF or Target Front Panel Designer formats.

Da, ies la jumatate.

Au venit radiatorul si controllerul cu 12 canale.
La prima impresie, controllerul nu are jack de power, ci suruburi la care legi firele transformatorului. Exista transformatoare cu fire sau trebuie sa sacrific mufa de la unul?
Apoi, radiatoarul de 300x140x20 mm sunt doua, nu unul (abia acum realizez ca am comandat doua .
