The body does use calories to heat cold water, but the body is very efficient. Let’s take an example wherein one cup of water is 32 degrees Fahrenheit (0 Celsius). You drink it, and your internal temperature is a normal 98.6 degrees Fahrenheit (37 Celsius). The body will spend about 8 calories to increase the water temperature. That’s it. It’s the caloric equivalent of 1/6th an Oreo cookie.
In case it’s of interest to you, the formula is pretty simple: It takes 1 calorie to raise 1 gram of water 1 degree Celsius. But, since we’re converting calories to the kilo-calories that we see on nutritional labels, we must divide the result by 1,000 to get your answer.
Even though ice water doesn’t burn a significant number of calories, proper hydration does provide a number of great benefits. So don’t let this information deter you – drink up!

From wiki.

It helps, so does taking very cold baths but, not significantly. Drinking water period is good for you..............

Although cold water will not burn a significant amount of calories it will provide the body with its need for hydration but MOST IMPORTANTLY FROM YOUR CONCERN POINT OF VIEW, IF YOU DRINK ENOUGH OF IT, IT WILL PREVENT YOU FROM DRINKING ANY KIND OF SODAS WHICH ARE LOADED WITH TONS OF CALORIES.
