Description

Technical Field

[0001] The present invention relates to the field of air conditioning, and in particular to a radiator and an air conditioner with a flow guide structure. Background Art

[0002] At present, with the annual development of the residential industry, the requirements for the exterior design and safety of buildings are becoming higher and higher. Most of the new residential buildings generally no longer use the wall-mounted air-conditioning outdoor unit bracket method, but set up air-conditioning positions, and grilles are set outside the air-conditioning positions to ensure the overall aesthetics; accompanied by this, the heat dissipation environment of the air-conditioning outdoor unit deteriorates. In the building grille, the temperature is more than 6°C higher than the environment outside the building, which is not conducive to the heat dissipation of the air-conditioning outdoor unit electronic control and is extremely unfavorable to the operating reliability of the whole machine; at high ambient temperatures, in order to ensure the reliability of the electronic control and reduce the heat, the variable frequency air conditioner usually adopts the method of reducing the refrigeration operation frequency, reducing the operating current, and thus reducing the module heat; but this method sacrifices cooling capacity in exchange for reliability, and cannot meet the user's requirements for cooling capacity; therefore, a structure of fixing the radiator on the heating module connected to the circuit board has emerged, and at the same time, the radiator is connected to the refrigerant circulation for heat dissipation.

[0003] At present, the refrigerant heat dissipation pipe above the radiator is prone to produce condensed water, and the produced condensed water is easy to flow to the pins of the first radiator and the power module, which makes the radiator short-circuit risk higher, thereby causing failure and damage to the control board, and further affecting the normal operation of the device. Therefore, it is of great significance to study how to reduce the impact of the refrigerant heat dissipation pipe on the radiator and thus improve the safety of the radiator.

[0004] Patent CN215724026U mentions an electric control box assembly and an air conditioner, the electric control box assembly includes an electric control module, an electric control box and a heat dissipation assembly, the electric control box is provided with a heat dissipation port, the electric control module is installed on the inner side of the electric control box, and the heating element of the electric control module corresponds to the heat dissipation port; the heat dissipation assembly includes a substrate and a refrigerant tube provided on the substrate, the substrate is installed on the outer side of the electric control box, and the refrigerant tube is connected to the heating element via the heat dissipation port; a first fixing groove is provided on the substrate, and a part of the tube body of the refrigerant tube is embedded in the first fixing groove; when the refrigerant tube is connected to the substrate, a part of the tube body of the refrigerant tube is embedded in the first fixing groove. Groove, the first fixed groove can limit the connection position of the refrigerant tube relative to the substrate, and then the refrigerant tube is fixed by a card slot or other connecting parts, so as to improve the position accuracy and stability of the refrigerant tube connected to the substrate. However, when the refrigerant tube is welded and connected to the structure, it is easy to burn the electronic control module and the wires connected to the electronic control module, thereby damaging the electronic control module and affecting its use. Although the first fixed groove is set with a slope in the direction away from the substrate and has a groove setting, its slope is set inside the groove where the refrigerant tube is embedded, and it cannot effectively discharge condensed water. Therefore, it is less effective in improving the influence of the refrigerant tube on the radiator.
