A plate for a heat exchange arrangement for the exchange of heat between a first and a second medium. The plate has a first heat transferring surface in contact with the first medium and a second heat transferring surface in contact with the second medium. The plate includes an inlet porthole for the first medium; an inlet porthole for the second medium, and an outlet porthole for the first medium. The first heat transferring surface includes a protrusion forming at least one ridge arranged to divide the heat transfer surface into at least a first region in direct thermal contact with the inlet porthole for the second medium, and a second region not in direct thermal contact with the inlet porthole for the second medium. The second region substantially surrounds the first region. The inlet porthole for the first medium is arranged in the first region, while the outlet porthole for the first medium is arranged in the second region. Moreover, the at least one ridge forms at least one elongated transfer channel arranged to convey the first medium from the first region to the second region.

A thin heat exchange panel includes a contact side that is in contact with a heat source and a plurality of heat exchange channels disposed in the contact side. A water inlet channel of the heat exchange panel is connected with a high-pressure pump for inputting high-pressure water, and a water outlet channel of the heat exchange panel is connected with a cooler to form a circulating cooling system. When the high-pressure pump is started, the high-pressure water quickly enters the water inlet channel. Reduced control holes communicating with the water inlet channel are configured to regulate the average flow rate and increase the speed of the water to bring a high-speed jet effect, which improves the heat exchange rate of the water in the heat exchange channels to achieve the effects of low damping, high heat dissipation efficiency and thinning.

An electric device has a housing and an active part in the housing that can be supplied with a high voltage and that generates heat when operated.
