Cold plate

A cold plate comprising:

• a housing comprising a metal base plate and a resin cover, wherein
• the metal base plate comprises:
• a base part;
• and
• a heat exchange part that transfers heat absorbed from a heating element to a refrigerant,
• the resin cover comprises an outer wall part joined to the base part,
• the housing has:
• an internal space, surrounded by the base part and the outer wall part, in which the heat exchange part is disposed;
• an inflow hole that communicates with the internal space and into which the refrigerant flows;
• and
• an outflow hole that communicates with the internal space and through which the refrigerant flows out,
• the resin cover further comprises:
• a low-temperature refrigerant flow path, disposed in the internal space, through which the refrigerant flows before absorbing heat from the heat exchange part;
• and
• a high-temperature refrigerant flow path, disposed in the internal space, through which the refrigerant flows after absorbing heat from the heat exchange part, and
• the high-temperature refrigerant flow path is separated from the low-temperature refrigerant flow path.
