Example one

Referring to fig. 1 and 2, a heat sink structure includes N heat sink units 100, where N is greater than or equal to 2, and each heat sink unit 100 is independent from each other and is integrated with each other. Each radiator unit 100 and a water pump, a cooling water jacket and a temperature adjusting device in the corresponding engine water-cooling system form a respective cooling system, and N sets of independent cooling systems form the cooling system of the whole superposition generator system together, and the cooling system has the function of dissipating heat in the water jacket in the atmosphere when a plurality of internal combustion engines are driven.

The N radiator units 100 are arranged in rows and columns in the longitudinal direction (up and down direction in FIG. 1) and in parallel in the transverse direction (left and right direction in FIG. 1), each row has one or at least two radiator units 100 stacked one on top of the other, and the radiator structure further includes a base 200, and the lowermost radiator unit 100 in each row is supported on the base 200. In the present embodiment, N radiator units 100 are arranged in row 4 and column 1, and each radiator unit 100 is commonly supported on the base 200, i.e. the base 200 supports the weight of the whole N radiator units 100, and a plate 300 may be provided outside the outermost radiator unit 100 to form a cabinet to accommodate each radiator unit 100.

In the present embodiment, the layout of each radiator unit 100 is a longitudinal flow structure. Each radiator unit 100 includes a first chamber 101, a radiator core 102, a radiator fan 103, an air guide cover 104, a second chamber 105, a water inlet pipe 106, and a water outlet pipe 107. The heat dissipation fan 103 and the wind scooper 104 constitute an air circulation component of the heat sink unit 100, and the operation principle thereof is the same as that of the prior art. In this embodiment, each radiator unit 100 may have two fans 103 spaced up and down, each fan 103 corresponds to one air guiding cover 104, and the radiator core 102 may correspond to the position of the fan 103, as shown in fig. 1, and the air guiding covers 104 are disposed between the fan 103 and the radiator core 102. The air guide cover 104 functions to ensure that the entire amount of air generated by the radiator fan 103 is guided to the radiator core 102 and flows through the radiator core 102, thereby improving the efficiency of the radiator fan 103. The axial relative positions of the heat dissipation fan 103 and the air guide cover 104 are generally as follows: 2/3 of the radial projection width of the fan blades of the heat dissipation fan 103 is in the

wind guide cover

104, and 1/3 of the radial projection width of the fan blades is outside the wind guide cover 104, so that the flow guide is increased, and the back pressure is reduced. The size of the radiator core 102 preferably corresponds to the diameter of the radiator fan 103.

The first chamber 101, the second chamber 105, the radiator core 102, the water inlet nozzle 106, and the water outlet nozzle 107 constitute a coolant circulation assembly of the radiator module 100. The first cavity 101 is located above the radiator core 102 as a liquid outlet cavity, has the function of an expansion water tank, can accommodate the expansion amount of the whole cooling liquid circulation pipeline, and simultaneously has the functions of pressure fixation and water supplement for the whole cooling liquid circulation pipeline. The second chamber 105 serves as a liquid inlet chamber and is located below the radiator core 102. The first chamber 101, the radiator core 102 and the second chamber 105 are in fluid communication. The inlet port 106 is disposed on the second chamber 105 and is in fluid communication with the second chamber 105, the outlet port 107 is disposed on the first chamber 101 and is in fluid communication with the first chamber 101, and the inlet port 106 and the outlet port 107 are connected to respective pipes (not shown) of the engine. The number of water outlet nozzles 107 per first chamber 101 may depend on the structure of the engine block, and as shown in the present embodiment, there are two water outlet nozzles 107 per first chamber 101.

The first chamber 101 of each radiator module 100 may be formed in an integral structure and then partitioned into N spaces, each corresponding to one radiator module 100, by the first partition 110.

The radiator structure adopting the longitudinal flowing water structure has simpler layout structure.

In operation, water or other coolant from the engine block enters the second chamber 105 through the water inlet port 106, flows upward through the radiator core 102, exchanges heat with outside air at the radiator core 102, enters the first chamber 102, flows out through the water outlet port 107, and returns to the engine block, thereby achieving circulation. In this process, the radiator fan 103 blows wind toward the radiator core 102, and accelerates heat exchange between the radiator core 102 and the outside air.

It follows that in this embodiment, the flow direction of the coolant is in-out from the bottom.

Example two

Referring to fig. 3 and 4, in the present embodiment, unlike the first embodiment, the flow direction of the cooling liquid is transverse. Further, each radiator unit 100 has an expansion tank 108 independent of the first chamber 101.

The N radiator units 100 are arranged in two rows in the transverse direction, at least two radiator units can be arranged in each row in the longitudinal direction in an up-and-down overlapping mode, the first chamber 101 of each radiator unit 100 is used as a liquid outlet cavity, the radiator units 100 arranged in the transverse direction are arranged on the side far away from each other, the second chamber 105 is used as a liquid inlet cavity, and the radiator units 100 are arranged in the space between the radiator units 100 arranged in the transverse direction. The water inlet nozzle 106 and the water outlet nozzle 107 are both disposed on the side of the two radiator 100 units which are juxtaposed in the lateral direction away from each other, and the water outlet nozzle 107 may be connected to the first chamber 101 through a water pipe. The outlet nozzle 107 is located above the inlet nozzle 106. The radiator core 102 is disposed between the first chamber 101 and the second chamber 105, and corresponds to the radiator fan 103. The positions of the first chamber 101 and the second chamber 105 may be interchanged as long as they are respectively located on the opposite sides of the radiator core 102 in the lateral direction.

The expansion tanks 108 are disposed at the uppermost portion of the entire radiator structure, and the first chambers 101 of the radiator units 100 located at the uppermost portion of each row may be directly communicated with the corresponding expansion tanks 108, e.g., opened at the corresponding positions, respectively. The first chambers 101 of the remaining radiator units 100 are communicated with the corresponding expansion tanks 108 through water ducts 109, and the water ducts 109 are provided on the sides of two radiator 100 units juxtaposed in the lateral direction away from each other.

Each expansion tank 108 may be formed in an integral structure and then partitioned into N spaces each corresponding to one radiator module 100 by the second partition plate 111.

The layout mode of the embodiment can increase the diameter of the heat dissipation fan 103 and reduce the wind speed of the heat dissipation fan 103, so as to achieve the purposes of reducing power consumption and noise. Thus, as shown in the figure, only one heat dissipation fan 103 can be provided for each radiator unit 100, so that the radiator structure is compact as a whole and the number of installed heat dissipation fans 103 is small.

The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter, referred to as a first portion and a second portion) in a unified manner, i.e., a fluid (gas, liquid or a mixture thereof) can flow along a flow path from the first portion or/and be transported to the second portion, and may be directly communicated between the first portion and the second portion, or indirectly communicated between the first portion and the second portion via at least one third member, which may be a fluid passage such as a pipe, a channel, a duct, a flow guide member, a hole, a groove, or a chamber allowing the fluid to flow therethrough, or a combination thereof.
