Background

Radiators on the current market are usually assembled and connected in series, and the interfaces of adjacent radiators are connected through a connecting device with double threads;

the prior application No. 201520226911.6, entitled "a novel radiator connecting structure", is a Chinese utility model patent, which utilizes the matching of the positive thread and the negative thread at the two ends of a screw connecting piece with the positive thread interface and the negative thread interface of a radiator, and the middle part is provided with a leak-proof gasket for sealing, but although the screw connecting piece of the structure is not disclosed in the published documents, in practice, a spline groove is necessarily arranged in the screw connecting piece, the screw connecting piece is rotated by the matching operation of an operating rod with spline teeth and the spline groove which pass through the interfaces at the two sides of the radiator, otherwise the screw connecting piece can not be used for connecting radiators, even though the connection is carried out by the mode, the screw connecting piece is not suitable for the series connection of too many radiators due to the limitation of the length of the operating rod, and the structure also has to ensure that the interfaces at the two sides of the radiators are coaxially arranged, otherwise the operating rod can not penetrate, therefore, the applicable radiators are limited;

current application number is 200520054654.9, the chinese utility model patent of the name "radiator coupling mechanism", it can connect first joint and second joint respectively with two radiators earlier, later connects first joint and second joint through the nut to connect in the outside, consequently can establish ties the radiator wantonly, does not receive the restriction of interface position simultaneously, but its still has following problem:

1. the first joint and the second joint are required to be respectively connected with the interfaces of the two radiators, and then the first joint and the second joint are connected by utilizing nuts, so that the mounting and connecting operation is troublesome.

2. Although the nut can be used for pressing the sealing ring at the joint of the first joint and the second joint, more leakage points still exist due to the existence of excessive connecting parts, for example, the joint of the first joint and the second joint with the corresponding interface of the radiator cannot form high-strength sealing.

3. The first joint and the second joint are of split structures and are connected through nuts, and overall strength is low.

4. In order to ensure that two ends of the connected nut are just matched and abutted to the interface end faces of two adjacent heating radiators, the threads in the first connector and the second connector are just matched and screwed in with the threads on the interfaces, once deviation exists, only one end of the nut is abutted to the interface end face on one heating radiator, the other end of the nut cannot be matched at all, and therefore the requirement on the machining precision is high.
