Figure 61 - Heat transfer over a box
Permission Pending
As you can see from the picture heat will rise which will cause the top of the box to get
hot. We will mount a heat sink and will use thermal ohms law to calculate the amount of
surface area we need to be able to cool the box effectively. As in the image above you
can see that we will be using fans to direct the air into the box by doing this we can
route the air to transfer the heat from the box to atmosphere. This box will also be
sealed to keep out acts of nature. For example water cannot get into the section of the
box that houses the electronics. We will be using fins to accomplish this task. The
picture below shows the type of fin that we will be using to accomplish this:
Figure 62 - Fins used to dissipate heat and keep elements out
Permission Pending
As you can see from the picture above we will be using fins to dissipate the heat from
the electronics in the sealed box. Water cannot get into this box and if it does it can
damage the entire system. On top of this box we will be mounting fans, which will
further dissipate the heat. With this enclosure and fans we will completely eliminate the
heat dissipation problem as well as the element of exposing moisture to the system,
which are two main problems that can compromise our system. The display will have a
similar design that will be clear such that the user can see the display and interact with
it. The buttons that will control the electronics will be waterproof buttons. These buttons
are shown below:
