I wrote a plugin for wordpress and i want it to refresh in every 3 hours i tried header("refresh:10800;url=example.php") but i couldn't get any result.
Thanks for your helps.

you could try with javascript:
setTimeout(function(){ window.location = 'example.com' },10800)
let us know how you get on in 3 1/2 hours or so...

You've gotten confused between the PHP header() function and the HTML HEAD section.
The PHP header( 'Location: newpage.htm' ); performs an instantaneous redirect to newpage.htm (and should be directly followed by a call to die()). There is no potential to delay that redirection.
Within the HTML <head> ... </head> section, you can use a META Tag to perform a delayed refresh or redirection:
<!-- Refresh the Current Page every 10 minutes (600 seconds) //-->
<meta http-equiv="refresh" content="600">
<!-- Redirect to Another Page with a Delay of 10 minutes (600 seconds) //-->
<meta http-equiv="refresh" content="600;url=http://anotherserver.com/">
