Embodiment Construction

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] In the research of the highly integrated electric control board, the inventor found that since the power device is a heat source, in order to avoid thermal failure due to excessive heat generation of the device, it is necessary to perform good heat dissipation on each power device, and the heat dissipation of the power device is usually through It is realized by installing a radiator on the surface of the power device. In addition, since each power device is a high-voltage device, in order to achieve a reasonable creepage ...

Abstract

The invention discloses a highly-integrated electrical control board and an electrical appliance. The control board includes a first substrate and a second substrate, wherein the first substrate and the second substrate are disposed opposite to each other; a strong current element which is disposed on a side surface, close to the second substrate, of the first substrate and comprises a highly-integrated intelligent power module which integrates a compressor intelligent power module and a fan intelligent power module; a weak current element which is disposed one a side surface, closes to the first substrate, of the second substrate and includes a micro-control unit. The strong current element is electrically connected with the weak current element, and a packaging material is disposed between the first substrate and the second substrate. The electrical control board has higher long-term use reliability, longer service life, and lower manufacturing cost.

Description

technical field [0001] The invention relates to the field of electrical appliance manufacturing, in particular, the invention relates to a highly integrated electric control board and electrical appliances. Background technique [0002] Intelligent Power Module (IPM, Intelligent Power Module) is an advanced power switching device, which is essentially a module that integrates power devices and their drive circuit chips; Intelligent Power Modules can play a role in the field of energy management that is difficult for other integrated circuits to achieve. The device performance directly affects the utilization efficiency of the energy system. The intelligent power module uses the insulated gate bipolar transistor (IGBT) as the core, and consists of a high-speed and low-power die, an optimized gate drive circuit, and a fast protection circuit. The core of the insulated gate bipolar transistor in the power module is generally high-speed type, and the driving circuit is close to...
