The Cooling System of the Zad RC: A Unique Approach to Multiple Powertrains

As we take a closer look at the cooling system on this car behind us, it becomes clear that it's a unique and innovative approach. The vehicle is the Zad RC, and we're currently at a test track in Brunting Thorp, England. If you haven't already, it's definitely worth checking out Nemo's Channel, as they have an abundance of videos on this car that can provide further insight into its capabilities.

The cooling system of the Zad RC is actually pretty unique because it's cooling two separate powertrains using a single circuit. On the side of the vehicle, you can see these two air ducts. One of them will be feeding air to a radiator, which is mounted at the back, and the other one will allow air to go into the 1.5 L engine as well as the Numatic paddle shifters.

Let's take a closer look at how the cooling systems of the Zad RC work out. There are actually two separate systems, each with its own dedicated radiator. Above the two rear tires, there will be air intakes that feed into these radiators. On one system, we have the engine, gearbox, two motors, and controllers. On the other system, we have the battery and intercooler. As you can see, the coolant is flowing through this radiator, cooling the liquid coolant, which is a water-ethylene glycol mix.

The coolant will then flow from the radiator first into the controllers, after passing through them, it will go through the two motors, and then into the engine coolant jackets. From there, it will flow into the coolant housing where the engine will also have an oil cooler, as well as a transmission oil cooler. This will cool off both of these components for the oil. The coolant will then flow back to the pump, through the radiator, and continue this loop. This loop is expected to flow at around 30 L per minute and need to reject approximately 40 Kow of energy.

The second cooling system is designed to cool the intercooler and battery. This system is also using a liquid flowing through it, which will cool the intake charge. What we have here is air flowing over that rear tire into the intake, going through this radiator, which then goes to a pump, over into the battery, through the battery, and then back to the intercooler before returning to the radiator. This system needs to dissipate about 30 Kow of power. It will run a diethylene glycol liquid through it for the battery system.

Let's take a closer look at the cooling system on the actual car. The air is coming in from the front, feeding through this radiator from the radiator itself. The coolant line is going to go to the battery, and then the battery will send that coolant up through the air to water intercooler. From there, it will flow back into your radiator before continuing. As the battery supplies 400 volts to the two electric motors, it's generating quite a bit of heat, so it needs to be liquid-cooled. The coolant which is this diethylene glycol fluid comes in through this inlet here and passes through the battery in kind of a wave-like form, ensuring that all the individual cells are cooled down before it comes out on the other end.

Looking at the other side of the car, we have cold air rushing through this radiator. The coolant running through this radiator is going to pass over that's going to go into the controller, then through the motors, and finally pass over into the engine before flowing back into the coolant housing where the transmission oil and engine oil will be cooled down. Then it flows back to this pump, into to this radiator.

brunting Thorp England now if you haven't already it's worth checking out Nemo's Channel they've got all kinds of videos on this car so you can learn more about it I'll have an annotation below as well as a link in the video description the cooling system of the zad RC is actually pretty unique because it's cooling two separate powertrains using a single circuit so here on the side of the vehicle you can see these two air ducts this one here air will be feeding a radiator which is mounted at the back and this one here will be allowing air to go in to feed the 1.5 L engine as well as air for the numatic paddle shifters okay so let's take a look at how the cooling systems of the zad RC work out so there's actually two separate systems each has its own dedicated radiator and there's going to be air intakes above the two rear tires uh which the air will feed through these radiators so on one system we've got the engine the gearbox the two Motors and the controllers uh and on the other system we have the battery and the intercooler so as your coolant is uh you've got your air flowing through this radiator here cooling the the liquid coolant the water ethylene glycol mix that's going to be going through it um and so that's going to go from the radiator first into the controllers after it passes through the controllers it's going to go through the two Motors then into the engine coolant jackets from the engine coolant jackets it will flow into this coolant housing where the engine will also have an oil cooler uh in that coolant housing so the coolant is going to flow over that oil cooler as well as the transmission oil cooler and cool off both of those two components uh for the oil then it will flow back to the pump back through the radiator and the loop continues and this is going to be flowing at around 30 L per minute um and it's going to need to reject around 40 Kow of energy so for the second cooling system we're going to be cooling the intercooler and the battery this is going to be cooling the intake charge so you're going to have a liquid flowing through it so what we've got is your air flowing over that rear tire into the intake going through your radiator that's going to go to a pump over into the battery through the battery through the intercooler and then back to the radiator so this is going to be about a 30 Kow of power that it needs to dissipate um and this is going to be running a dialectric liquid through it um for the battery system so let's take a look at the cooling system on the actual car so the air is going to be coming through the front here feeding through this radiator from the radiator it's pass through these coolant lines uh the coolant line is going to go to the battery the battery is then going to send that coolant up through the air to water intercooler and then from the air to water intercooler that coolant is going to come back into your radiator and then the system will continue now as the battery is supplying 400 volts to the two electric motors it's going to be generating quite a bit of heat so it needs to be liquid cooled so the coolant which is a dialectric fluid will come in through this Inlet here pass through the battery in kind of a wave like form uh to make sure that it cools all of the individual cells and then it'll be coming out on this end here now let's look at the other side of the car so we've got our cold air rushing through this radiator here on the left side that coolant that's running through this radiator is going to pass over that's going to go into the controller then through the motors then pass over into the engine it'll go run through the engine coolant jackets over into this coolant housing right here where the transmission oil and engine oil will be cooled and then it's going to run back to this pump uh into to this radiator so thank you for watching if you have any questions or comments feel free to leave them below and please head over to niss
