<p>The utility model provides an electric power conversion device and a refrigerator. The task of the utility model is to obtain an electric appliance product with a high degree of freedom of the layout of components. According to the electric power conversion device of the utility model, one or more semiconductor devices (3) installed on an electronic printing substrate (2) is accommodated in an electric appliance component case (9). The electric power conversion device is characterized in that: electric power conversion device is formed of the following structure: the electric power conversion device is provided with a heat pipe; the heat pipe is provided with a heated portion (5) arranged to be in contact with the one or more semiconductor devices (3), a heat-conducting portion (6) arranged to be in contact with the heated portion and a heat radiation portion (7) arranged to be in contact with the heat-conducting portion. A heat radiation surface of the heat radiation portion (7) is configured along the external contour of the electric appliance component case (9), and the heat radiation portion (7) is configured to be at a position higher than the heated portion (5). Refrigerant inside the heat pipe cycles spontaneously by means of the gravity and a temperature gradient. The utility model also provides a refrigerator comprising the above power conversion device in the inside portion.</p> |
