Title:
HEAT DISSIPATION PIECE ASSEMBLY AND ELECTRIC OIL HEATER
Document Type and Number:
WIPO Patent Application WO/2021/218211
Kind Code:
A1
Abstract:
A heat dissipation piece assembly and an electric oil heater. The heat dissipation piece assembly comprises a first heat dissipation piece (10) and a second heat dissipation piece (20) connected to each other; an oil delivery channel (30) for delivering heat transfer oil is provided between the first heat dissipation piece (10) and the second heat dissipation piece (20); and the oil delivery channel (30) comprises, in a direction from bottom to top, a lower channel, a middle channel, and an upper channel that are communicated in sequence, a cross-sectional area of the lower channel being larger than that of the middle channel, and the cross-sectional area of the middle channel being smaller than that of the upper channel. The portion of the oil delivery channel (30) having a larger cross-sectional area can contain more heat transfer oil, store larger amount of heat, and transfer more heat, such that the temperature of the upper portion of the heat dissipation piece assembly can be kept within a certain range, thus preventing excessively high temperature of the upper portion region of the heat dissipation piece assembly while meeting the heating demand.
