Further, the groove adapted with described coolant conduits it is respectively equipped with on the joint face of described heat-conducting substrate and heat conduction fixed plate, enable described coolant conduits to be inlaid between described heat-conducting substrate and heat conduction fixed plate, and be in close contact with described heat-conducting substrate and heat conduction fixed plate.
Further, the surface of described groove is evenly coated with heat-conducting silicone grease.
Further, what described coolant conduits took the shape of the letter U is arranged between described heat-conducting substrate and heat conduction fixed plate.
Further, what described coolant conduits took the shape of the letter U is arranged between described heat-conducting substrate and heat conduction fixed plate, and makes end bends be placed in outside described heat-conducting substrate and heat conduction fixed plate.
Further, it is screwed between described heat-conducting substrate and described heat conduction fixed plate.

Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
As Figure 1-4, the chiller of the frequency conversion drive module of a kind of convertible frequency air-conditioner, including coolant conduits 12, heat-conducting substrate 13 and heat conduction fixed plate 14.Described heat conduction fixed plate 14 is screwed in the one side of heat-conducting substrate 13, makes both compact siro spinning technology.It is screwed installation frequency conversion drive module 15 on the another side of described heat-conducting substrate 13, makes both be in close contact.It is respectively equipped with the groove 16 suitable with coolant conduits 12 on the joint face of described heat-conducting substrate 13 and heat conduction fixed plate 14, makes coolant conduits 12 overall to embed in groove 16.Described groove 16 can be U-shaped, enables described coolant conduits to be completely embedded into, and increases the effect of heat transfer.Or, as shown in Figure 5 and Figure 6, described groove 16 can also be two parallel straight troughs, makes the end bends of described coolant conduits 12 be placed in outside heat-conducting substrate 13 and heat conduction fixed plate 14, it is simple to process and install.Further, described groove 16 cross section can be the semicircle identical with coolant conduits 12 diameter, it is simple to embed the operation installed.Described groove 16 surface, and the contact surface of frequency conversion drive module 15 and heat-conducting substrate 13 scribbles heat-conducting silicone grease the most uniformly, improves the efficiency of heat transfer.
As it is shown in fig. 7, the present invention connects within air-conditioning systems, its operation principle is:
Gaseous coolant through the High Temperature High Pressure of compressor 1 compression passes through oil eliminator 2, and by coolant and lubricating oil separation, coolant enters outdoor heat exchanger 4 by the C end of cross valve 3, and lubricating oil enters gas-liquid separator 11.The heat exchange first in outdoor heat exchanger 4 of the gaseous coolant of High Temperature High Pressure is condensed into the liquid refrigerants of medium temperature and medium pressure, the liquid refrigerants of medium temperature and medium pressure enters the chiller 6 of the present invention after heating electronic expansion valve module 5, and carry out secondary heat exchange with frequency conversion drive module wherein, subsequently enter subcooler 7 and carry out three i.e. cooling twice of heat exchange, medium temperature and medium pressure coolant after cooling enters each indoor pusher side by branch pipe, first pass through indoor electronic expansion valve 9 in indoor and carry out the decrease temperature and pressure that throttles, the liquid refrigerants entrance indoor heat exchanger 10 of low-temp low-pressure carries out four heat exchange and i.e. evaporates, low-temp low-pressure gaseous coolant after evaporation enters the E end of cross valve 3 and enters gas-liquid separator 11 by S end.In gas-liquid separator 11, carry out gas-liquid separation, make pure gaseous coolant enter compressor 1 and be compressed.So circulation, makes air-conditioning while properly functioning, effectively lowers the temperature frequency conversion drive module, and avoids the conventional impact on air-conditioner efficiency.
Part that the present invention does not relate to is the most same as the prior art maybe can use prior art to be realized.
