In use, the air bladder is inserted into the pipeline, and by continuously pulling the pull rod left and right, the piston moves left and right, allowing air to continuously enter the air bladder through the air inlet block, causing its volume to continuously increase and adhere to the inner wall of the pipeline for sealing. It is relatively simple to operate and easy to use.

The utility model discloses a splicing type box opening clamping strip, and relates to the technical field of box opening connecting structures, the splicing type box opening clamping strip comprises an outer box shell and an inner container body, and further comprises a clamping strip body, one end of the clamping strip body is clamped with the outer box shell, the other end of the clamping strip body is clamped with the inner container body, the two ends of the clamping strip body are both of an elastic buckle structure, and a cavity is formed in the clamping strip body. The sealing process is simplified; the ruffled edge structure is arranged at the joint of the outer box shell and the clamping strip body and abuts against the inverted buckle structure on the clamping strip body, and it is ensured that the clamping strip body is firmly connected with the outer box shell; an inclined back-off structure is also arranged at the joint of the clamping strip body and the liner body, so that the clamping force is enhanced; in addition, the mounting clamping groove is formed in the clamping strip body and can be used for mounting a lamp strip; a square hole is further formed in the clamping strip body and used for containing a corner brace. By optimizing the clamping strip structure, the purposes of quick connection, installation procedure simplification and cost reduction are achieved, and meanwhile the stability and attractiveness of products are improved.

The embodiment of the invention discloses a machining method of a heat exchange part. The machining method of the heat exchange part comprises the steps that a liquid cooling layer is obtained; bonding layers are bonded to the two sides of the liquid cooling layer respectively, and a prefabricated liquid cooling layer is formed; cutting the prefabricated liquid cooling layer and forming a runner groove; obtaining a first cover plate and a second cover plate; adhering the first cover plate to the first side of the prefabricated liquid cooling layer; and the second cover plate is pasted to the second side of the prefabricated liquid cooling layer, so that the first cover plate, the second cover plate and the prefabricated liquid cooling layer define a flow channel at the flow channel groove. Therefore, the first cover plate can be bonded with the first side of the prefabricated liquid cooling layer, the second cover plate can be bonded with the second side of the prefabricated liquid cooling layer, sealing connection of the first cover plate, the second cover plate and the prefabricated liquid cooling layer is achieved through bonding, the sealing technology can be simplified, and therefore the machining difficulty of the heat exchange piece is lowered.

The embodiment of the invention discloses a heat exchange piece, a heat exchange module and electronic equipment, the heat exchange piece comprises a first cover plate, a second cover plate and a middle layer which are arranged in a stacked mode, a runner groove is formed in the middle layer, and the runner groove is arranged in the thickness direction of the middle layer in a penetrating mode; the middle layer comprises a liquid cooling layer and bonding layers arranged on the two sides of the liquid cooling layer, the liquid cooling layer and the bonding layers on the two sides jointly form the side wall of the flow channel groove, and the first cover plate and the second cover plate are connected with the liquid cooling layer in a sealed mode through the bonding layers. And the first cover plate, the second cover plate and the middle layer define a flow channel at the flow channel groove. Therefore, the bonding sealing of the first cover plate, the second cover plate and the liquid cooling layer can be realized by utilizing the bonding layer, the sealing process can be simplified, and the processing difficulty of the heat exchange piece is also reduced.
