Description
本發明係有關於熱交換之技術，尤其是指一種地溫熱交換系統及其地溫熱發電與地溫熱泵系統。The present invention relates to heat exchange technology, and more particularly to a geothermal heat exchange system and a geothermal power generation and geothermal heat pump system thereof.
井下熱交換器其主要目的是為了地面與地底，例如：土壤或地下水，進行熱交換，熱交換的方式可由地面向地底取熱或將地面多餘熱量放置於地底，第一個方式通常是作為暖房或發電用，第二個方式通常應用於冷房。The main purpose of the downhole heat exchanger is to exchange heat between the ground and the ground, such as soil or groundwater. The heat exchange method can take heat from the ground to the ground or place the excess heat on the ground. The first way is usually as a greenhouse. Or for power generation, the second method is usually applied to cold rooms.
井下熱交換器一般分為U型管類型、盤管及類殼管等，而通常類殼管具有較大的熱交換量。請參閱第1圖所示，該圖係為類殼管熱交換器示意圖。該類殼管熱交換器11設置於一地井10內。該地井10內具有流體12以與該類殼管熱交換器11內的工作流體進行熱交換。不過由於類殼管熱交換器11形態上的限制，類殼管熱交換器11其外部流體12流動上效率較差，此類流動不均勻通常可歸納為(1)外部流體於小管外側的不均勻流動以及(2)小管內之工作流體的不均勻流動。其中，第(1)點之主要原因是上下兩端的分流及合流機構限制外部流體流動，如第1圖中，類殼管熱交換器11的兩端具有盤體110，其係阻礙井內流體流至類殼管熱交換器11之熱交換管體，而第(2)點則是因為小管的分布及公差所造成，為了保有較大的熱傳量及外部流體流動之效果，故以較特殊的外部結構設計，此外部結構設計過程中面臨內部工作流體之流動均勻性之問題，所以必須調整 小管直徑以達到壓降均勻性。Downhole heat exchangers are generally classified into U-tube types, coils, and shell-like tubes, and generally the shell-like tubes have a large heat exchange amount. Please refer to Figure 1, which is a schematic diagram of a shell-and-tube heat exchanger. The shell and tube heat exchanger 11 is disposed in a well 10. The well 10 has a fluid 12 therein for heat exchange with a working fluid within the shell and tube heat exchanger 11. However, due to the limitation of the shape of the shell-and-tube heat exchanger 11, the shell-and-tube heat exchanger 11 has a poor efficiency in flowing the external fluid 12. Such flow unevenness can be generally classified into (1) unevenness of the external fluid outside the small tube. Flow and (2) uneven flow of working fluid within the small tube. The main reason of the point (1) is that the splitting and merging mechanisms at the upper and lower ends limit the external fluid flow. As shown in FIG. 1, the shell-and-tube heat exchanger 11 has a disk body 110 at both ends thereof, which hinders the fluid in the well. Flow to the heat exchange tube of the shell-and-tube heat exchanger 11, and point (2) is caused by the distribution and tolerance of the small tube, in order to maintain the effect of large heat transfer and external fluid flow, Special external structure design, this external structure design process faces the problem of the uniformity of the internal working fluid flow, so it must be adjusted The diameter of the small tube is used to achieve uniformity of pressure drop.

再回到第2A圖所示每一個歧管組21a~21b(圖中僅示21a~21b)係由複數個歧管210a~210b所構成，其係分別與該第一主管20與該第二主管22相連通。在本實施例中，每一個歧管組所具有的歧管長度相同，但不同歧管組21a~21b所具有的歧管210a與210b長度不同。要說明的是，第2A圖雖僅標示歧管組21a~21b，但歧管組之數量並非以兩組為限制，使用者可以根據需求而設置多組歧管組。Returning to each of the manifold groups 21a-21b shown in FIG. 2A (only 21a-21b in the figure) is composed of a plurality of manifolds 210a-210b, which are respectively associated with the first main pipe 20 and the second The supervisor 22 is connected. In the present embodiment, each of the manifold groups has the same length of the manifold, but the manifolds 210a and 210b of the different manifold groups 21a to 21b have different lengths. It should be noted that although FIG. 2A only indicates the manifold groups 21a-21b, the number of manifold groups is not limited by two groups, and the user can set multiple groups of manifolds according to requirements.
請參閱第3與第4圖所示，在本實施例中，以歧管組21a為例，其所具有的複數個歧管210a係分別連接該第一主管20上的一排第一通孔200以及連接該第二主管22上最下方的一排第二通孔223。在本實施例中，每一個歧管組21a~21d 所具有的歧管結構，係以第5A圖所示之歧管組21a之歧管210a為所有歧管組之歧管代表，每一歧管210a具有一第一連接段2100、一流路段2101以及一第二連接段2102。該第一連接段2100，其係具有該第一端2103與對應之第一通孔200相連接。該流路段2101，其係與該第一連接段2100相連接。該第二連接段2102，其係與該流路段2101相連接，該第二連接段2102具有該第二端2104與對應之第二通孔223相連接。在一實施例中，歧管210a可以為一體成形之管體結構，在另一實施例中，歧管210a為由複數個子歧管所連接而成。要說明的是，該第一主管20、第二主管22以及歧管210a可以為導熱性結構良好的材質所構成，例如銅，但不以此為限制。Referring to the third and fourth figures, in the embodiment, the manifold group 21a is taken as an example, and the plurality of manifolds 210a are respectively connected to a row of first through holes on the first main pipe 20. 200 and connecting a lower row of second through holes 223 on the second main pipe 22. In this embodiment, each manifold group 21a-21d The manifold structure has a manifold 210a of the manifold group 21a shown in FIG. 5A as a manifold representative of all manifold groups, and each manifold 210a has a first connecting section 2100, a first-class road section 2101, and A second connecting section 2102.

It should be noted that the first main pipe 20, the second main pipe 22, and the manifold 210a may be made of a material having a good thermal conductivity structure, such as copper, but is not limited thereto.
接下來說明本發明之歧管組所具有之歧管的技術特徵。誠如前述，為了讓歧管內的工作流體與管外的流體進行有效率的熱交換，如第5B圖所示，其係為本發明之歧管組局部示意圖，在本發明之歧管組所具有之歧管的配置之特徵之一，在於讓相鄰之歧管間距有一間距d。例如：在第5B圖中，歧管組21a之歧管210a與歧管組21b之歧管210b之間的間距d係大於等於5mm，以讓外部之流體可以均勻通過每一個歧管210a~210c周圍，讓流體可以和歧管210a~210c內的工作流體進行熱交換。此外，請同時參閱第3與第4圖所示，歧管組21a~21d中所具有之歧管之另一特徵在於，每一歧管組21a~21d的歧管中的第一連接段2100以及第二連接段2102與其他組的第一連接段2100以及第二連接段2102在徑向上的長度並不相同，使得相鄰之不同歧管組所具有 之複數個歧管在徑向(r)間具有長短差以及在軸向(t)間具有長短差，而形成交錯的配置，進而增加歧管的數量。以第3圖來說明，每一歧管組21a~21d的歧管在徑向上具有不同之第一連接段長度d1~d4，因此透過複數排第一通孔200所產生的高低差以及第一連接段之不同長度d1~d4，使得各歧管產生交錯的配置。同理，如第4圖所示，每一歧管之第二連接段2102也是相同之原理，在此不做贅述。Next, the technical features of the manifold possessed by the manifold group of the present invention will be described. As described above, in order to allow efficient exchange of the working fluid in the manifold with the fluid outside the tube, as shown in FIG. 5B, it is a partial schematic view of the manifold group of the present invention, in the manifold group of the present invention. One of the features of the configuration of the manifold is that there is a spacing d between adjacent manifolds. For example, in Figure 5B, the spacing d between the manifold 210a of the manifold set 21a and the manifold 210b of the manifold set 21b is greater than or equal to 5 mm so that external fluid can pass uniformly through each of the manifolds 210a-210c. Surrounding, the fluid is allowed to exchange heat with the working fluid within the manifolds 210a-210c. In addition, please refer to FIGS. 3 and 4 at the same time, another feature of the manifolds included in the manifold groups 21a-21d is that the first connection segments 2100 in the manifolds of each manifold group 21a-21d And the length of the second connecting section 2102 and the first connecting section 2100 and the second connecting section 2102 of the other group are not the same in the radial direction, so that the adjacent different manifold groups have The plurality of manifolds have a length difference between the radial direction (r) and a length difference between the axial directions (t) to form a staggered configuration, thereby increasing the number of manifolds. As shown in FIG. 3, the manifolds of each manifold group 21a-21d have different first connection segment lengths d1~d4 in the radial direction, so the height difference generated by the plurality of first through holes 200 and the first The different lengths d1 to d4 of the connecting sections result in a staggered configuration of the manifolds. Similarly, as shown in FIG. 4, the second connecting section 2102 of each manifold is also the same principle, and will not be described herein.
此外，由於本發明之歧管為三維度之交錯配置，因此相鄰歧管組所具有的歧管長度並不相同。又，每一歧管內的工作流體的流量是否均勻，是影響到整體地溫熱交換系統的熱交換效果之重要因素，而工作流體在流經歧管內所產生之壓降會影響到歧管內工作流體的流量，為了讓本發明每一歧管內的工作流體流量均勻，以產生良好的熱交換效果，本發明中之其中至少一歧管組所具有之歧管係由複數段的子歧管組成，相鄰子歧管之內管徑不同，使得長度不同的歧管也可以產生相匹配的壓降。要說明的是，本發明所謂壓降相匹配的意思，係指工作流體在不同管長的歧管內所產生的壓降相同或者是在許可的誤差範圍內。In addition, since the manifolds of the present invention are in a three-dimensional staggered configuration, the adjacent manifold groups have different manifold lengths. Moreover, whether the flow rate of the working fluid in each manifold is uniform is an important factor affecting the heat exchange effect of the overall warm heat exchange system, and the pressure drop generated by the working fluid flowing through the manifold may affect the difference. The flow rate of the working fluid in the tube is such that the flow rate of the working fluid in each manifold of the present invention is uniform to produce a good heat exchange effect, and at least one of the manifold groups in the present invention has a manifold system The sub-manifolds are composed, and the inner diameters of the adjacent sub-manifolds are different, so that the manifolds with different lengths can also produce a matched pressure drop. It should be noted that the meaning of the so-called pressure drop matching in the present invention means that the pressure drop generated by the working fluid in the manifolds of different pipe lengths is the same or within the allowable error range.
請參閱第6A圖所示，該圖係為本發明之不同管長之歧管示意圖。舉例而言，如果在下列設計條件下：地溫熱交換系統取熱量：250kW(千瓦)；地溫熱交換系統歧管數：40支歧管；每一歧管外徑：12.7mm(毫米)；每一歧管內徑：10.7mm(毫米)；最長歧管210a長：11m(米)； 最短歧管210d長：9m(米)；最大單支壓降：4455Pa(帕,N/m2 )；最大全部壓降：178kPa(帕,N/m2 )；工作流體：水；歧管材質：銅管。Please refer to FIG. 6A, which is a schematic diagram of a manifold of different pipe lengths of the present invention. For example, if under the following design conditions: geothermal heat exchange system takes heat: 250 kW (kilowatt); geothermal heat exchange system manifold: 40 manifolds; each manifold outer diameter: 12.7 mm (mm) Inner diameter of each manifold: 10.7 mm (mm); longest manifold 210a length: 11 m (meter); shortest manifold 210d length: 9 m (meter); maximum single pressure drop: 4455 Pa (Pa, N/m 2 Maximum full pressure drop: 178 kPa (Pascal, N/m 2 ); working fluid: water; manifold material: copper tube.
依照上述設計，最長歧管210a與最短歧管210d長度差約2m。在還沒有調整壓降前，經過計算可以得知工作流體在歧管210a之壓降為4455Pa，歧管210d之壓降為3513Pa。 在本實施例中，由於具有最小歧管長度之歧管組21d所具有之歧管210d具有最短之管長且具有最小之壓降3513pa，因此可以該最小長度之歧管210d之壓降為基準，對於歧管長度大於歧管210d之歧管，透過複數段子歧管相接而成。對每一歧管而言，相鄰子歧管之內管徑不同，使由該複數段子歧管組成之歧管所具有之壓降與該最短之管長的歧管之壓降相匹配。請參閱第6B圖所示，以歧管210a為例，為了達到與該歧管210d相匹配之壓降，歧管210a可以由兩段子歧管211a與212a相接而形成具有不同管徑的歧管。According to the above design, the length of the longest manifold 210a and the shortest manifold 210d is about 2 m. Before the pressure drop has been adjusted, it can be calculated that the pressure drop of the working fluid in the manifold 210a is 4455 Pa, and the pressure drop of the manifold 210d is 3513 Pa. In the present embodiment, since the manifold 210d having the minimum manifold length has the manifold 210d having the shortest pipe length and having the smallest pressure drop 3513pa, the pressure drop of the minimum length manifold 210d can be used as a reference. For a manifold having a manifold length greater than the manifold 210d, the plurality of sub-manifolds are connected to each other. For each manifold, the inner diameters of the adjacent sub-manifolds are different, such that the pressure drop of the manifold consisting of the plurality of sub-manifolds matches the pressure drop of the manifold of the shortest tube length. Referring to FIG. 6B, taking the manifold 210a as an example, in order to achieve a matching pressure drop with the manifold 210d, the manifold 210a can be connected by the two sub-manifolds 211a and 212a to form a different diameter. tube.
第6B圖之實施例中，為了將長度為11m的歧管210a壓降調整成與長度為9m之歧管210d一樣，可以採用長度6m之子歧管212a，其內徑10.7mm，壓降為2342Pa與長度為5m之子歧管211a，其內徑11.9mm，壓降為1178Pa相接，而使得整體歧管210a’之總壓降則為3520Pa。透過上述之方式，可以在歧管總長度不變之條件下，利用多段內徑變化之子歧管組合以調整壓降。要說明的是，子歧管相接的方式可以為直接在子歧管相接的位置上透過焊接之方式來結合； 或者是，透過如第6B圖所示之套管213a~215a來將子歧管組合。此外，要說明的是，子歧管的長度以及口徑的選擇，可以根據需求而定，並無一定之限制，一般而言使用者可以採用規格品，如下表一所示，搭配以下方程式(1)的演算來找到合適的子歧管組合。In the embodiment of Fig. 6B, in order to adjust the pressure drop of the manifold 210a having a length of 11 m to be the same as the manifold 210d having a length of 9 m, a sub-manifold 212a having a length of 6 m, having an inner diameter of 10.7 mm and a pressure drop of 2342 Pa may be used. The sub-manifold 211a having a length of 5 m has an inner diameter of 11.9 mm and a pressure drop of 1178 Pa, so that the total pressure drop of the entire manifold 210a' is 3520 Pa. In the above manner, the sub-manifold combination of multiple stages of inner diameter can be utilized to adjust the pressure drop under the condition that the total length of the manifold is constant. It should be noted that the manner in which the sub-manifolds are connected may be directly combined at the position where the sub-manifolds are connected by welding; Alternatively, the sub-manifolds are combined through the sleeves 213a to 215a as shown in Fig. 6B. In addition, it should be noted that the length and diameter of the sub-manifold can be selected according to the requirements, and there is no certain limit. Generally, the user can use the specifications, as shown in Table 1 below, with the following equation (1) The calculus to find the right sub-manifold combination.
除了前述之方式外，在另一實施例中，挑選子歧管之方式為下列方式：首先於該複數段子歧管中選擇其中之一子歧管，使其內管徑與該最小管長之歧管所具有之內管徑相同，且其長度係為該最小管長之一半。接著，其他段的子歧管在依據前述方程式(1)的方式來挑選合適的子歧管並將其拼接。此外，要說明的是，雖然前述實施例係以最小歧管長度之歧管的壓降為基準，再對大於該最小歧管長度之歧管進行分段以及不同內徑之子歧管來組合，來降低壓降而與最小長度之歧管的壓降匹配。但在另一實施例中，也可以最大子歧管之壓降為基準，對於管長小於該最大長度之歧管來進行分段以及不同內徑之子歧管來組合，來增加歧管的壓降而與最大長度之歧管之壓降相匹配。不過在實際實施上，雖然前述兩種方式都可以讓各歧管的壓降匹配，不過如果是前者的話，由於是降低壓降，因此對於提供工作流體動力的泵浦而言，所需要輸出的動力會比 後者增加壓降的方式來的節省能源，所以在實際施作上多會採用降低壓降之方式。In addition to the foregoing manners, in another embodiment, the manner of selecting the sub-manifolds is as follows: first selecting one of the sub-manifolds in the plurality of sub-manifolds, so that the inner diameter of the tube is different from the minimum length of the tube The tube has the same inner diameter and the length is one-half of the minimum length. Next, the sub-manifolds of the other segments pick the appropriate sub-manifolds and splicing them in the manner according to equation (1) above. In addition, it is to be noted that although the foregoing embodiments are based on the pressure drop of the manifold of the minimum manifold length, the manifolds that are larger than the minimum manifold length are segmented and sub-manifolds of different inner diameters are combined. To reduce the pressure drop and match the pressure drop of the smallest length manifold. However, in another embodiment, the pressure drop of the largest sub-manifold can also be used as a reference, and the manifold having a tube length smaller than the maximum length is combined with the sub-manifolds of different inner diameters to increase the pressure drop of the manifold. It matches the pressure drop of the manifold of the largest length. However, in practice, although the above two methods can match the pressure drop of each manifold, if it is the former, because it is to reduce the pressure drop, the output is required for the pump that provides the working fluid power. Power will be better than The latter increases the pressure drop to save energy, so in the actual application, the method of reducing the pressure drop will be adopted.
除了前述透過多個子歧管的方式來調整壓降匹配之外，在另一實施例中，也可以透過調整各歧管與第一主管以及第二主管相接之管段的口徑來控制壓降匹配。要說明的是，對於歧管之開口屬於擴口之結構，其係代表歧管開口由端部位置逐漸縮小至與歧管管徑相同的口徑，亦即開口之口徑大於歧管之內徑，此種擴口結構可以降低工作流體流經歧管內部時所產生的壓降；而對於歧管之開口屬於縮口之結構，其係代表歧管開口由端部位置逐漸增加至與歧管管徑相同的口徑，亦即開口之口徑小於歧管之內徑，此種縮口結構可以增加工作流體流經歧管內部時所產生的壓降。In addition to the above-described adjustment of the pressure drop matching by means of a plurality of sub-manifolds, in another embodiment, the pressure drop matching can also be controlled by adjusting the caliber of the pipe sections of each manifold that is in contact with the first main pipe and the second main pipe. . It should be noted that the opening of the manifold is a flared structure, which means that the opening of the manifold is gradually reduced from the end position to the same diameter as the diameter of the manifold, that is, the diameter of the opening is larger than the inner diameter of the manifold. The flared structure can reduce the pressure drop generated when the working fluid flows through the inside of the manifold; and the opening of the manifold is a shrinkage structure, which means that the manifold opening is gradually increased from the end position to the manifold tube. The same diameter, that is, the diameter of the opening is smaller than the inner diameter of the manifold, and the shrinkage structure can increase the pressure drop generated when the working fluid flows through the inside of the manifold.
根據前述之擴口與縮口結構對於壓降的關係，可以用來調整本發明工作流體於各歧管內所產生的壓降。如同前 述透過複數個子歧管的方式一樣，如果是要透過擴口或縮口結構調整壓降，在一實施例中，可用最小管長之歧管的壓降為基準，將管長大於該最小管長之歧管與第一主管或/及第二主管相接的第一連接段或第二連接段的口徑予以擴口，形成如第7A圖之結構。在第7A圖中，以最長的歧管210a為例，其第一連接段2100與第二連接段2102具有擴口結構。反之，如果是要透過擴口或縮口結構調整壓降，在另一實施例中，可用最大管長之歧管的壓降為基準，將管長小於該最大管長之歧管與第一主管或/及第二主管相接的第一連接段或第二連接段的口徑予以縮口，形成如第7B圖之結構。在第7B圖中，以最短的歧管210d為例，其第一連接段2100與第二連接段2102具有縮口結構，連接後之結果係如第3圖與第4圖所示，歧管210d與第一主管20或第二主管22相連接之位置具有縮口結構。透過第7A圖與第7B圖所示的方式，可以調整歧管內工作流體所產生的壓降，使各歧管間的壓降相匹配。According to the aforementioned relationship between the flaring and the shrinkage structure for pressure drop, it can be used to adjust the pressure drop generated by the working fluid of the present invention in each manifold. As before In the same manner as the plurality of sub-manifolds, if the pressure drop is to be adjusted through the flare or neck structure, in one embodiment, the pressure drop of the manifold with the smallest pipe length can be used as a reference, and the pipe length is greater than the minimum pipe length. The diameter of the first connecting section or the second connecting section where the tube is in contact with the first main pipe or/and the second main pipe is flared to form a structure as shown in Fig. 7A. In FIG. 7A, taking the longest manifold 210a as an example, the first connecting section 2100 and the second connecting section 2102 have a flared structure. On the other hand, if the pressure drop is to be adjusted through the flaring or shrinkage structure, in another embodiment, the manifold with the largest pipe length can be used as the reference, and the manifold having the pipe length less than the maximum pipe length and the first supervisor or / And the diameter of the first connecting section or the second connecting section where the second main pipe is connected is shrunk to form a structure as shown in FIG. 7B. In FIG. 7B, taking the shortest manifold 210d as an example, the first connecting section 2100 and the second connecting section 2102 have a necking structure, and the result of the connection is as shown in FIG. 3 and FIG. 4, the manifold The position where 210d is connected to the first main pipe 20 or the second main pipe 22 has a constricted structure. Through the manner shown in Figures 7A and 7B, the pressure drop generated by the working fluid in the manifold can be adjusted to match the pressure drop between the manifolds.

The geothermal power generation system 3 includes a geothermal heat exchange system 2, a pump 31, and a power generating device 32.

Implementation. The pump 31 provides the power of the circulating fluid of the working fluid 91. In the embodiment, the pump 31 is coupled to the second main pipe 22 of the geothermal heat exchange system 2 to extract the working fluid in the second main pipe 22. 91. The power generating device 32 further has an evaporator 320 and a turbine generator 321 And a condensation module 322. The evaporator 320, a turbine generator 321 and the condensation module 322 are coupled together by a circulation line 323. The evaporator 320 is in communication with the pump 31 to receive the working fluid 91. The evaporator 320 has the circulation line 323 therein and a liquid cold fluid 93 therein. The evaporator heat exchanges the liquid cold fluid 93 with the working fluid 91 to convert the liquid cold fluid 93 into a hot fluid 92.

The working fluid 91 is caused to enter by the second main pipe 22 and then flow out by the first main pipe 20. In addition, it should be noted that although the pump 31 in this embodiment is coupled to the second main pipe 22, it is not limited thereto. For example, as shown in FIG. 8B, in another embodiment, the inlet of the pump 31 is connected to the evaporator 320 to provide a conduit for the flow of the working fluid 91 and its outlet to the first header 20. By means of the connection mode of FIG. 8B, it is possible to prevent the pump 31 from receiving the output from the second main controller 22. The high temperature working fluid, in turn, increases the life of the pump 31.

該室內熱交換系統42係包括有一熱交換模組420以及一抽風機421。該熱交換模組420，其係提供一第一管路4201以及一第二管路4202通過，該第一管路4201與該泵浦41耦接，以提供該工作流體91通過，該第二管路4202提供由室內環境43所抽入之一環境流體94。該第二管路4202內之環境流體在該熱交換模組420內與該工作流體91進行熱交換，該熱交換模組420將該工作流體91輸送回該第一主管20。該抽風機421，與該第二管路4202相耦接，該熱交換模組420抽取該環境流體94，並將與該工作流體91進行熱交換之該環境流體94傳輸至該室內環境43。至於傳輸至該室內環境43之環境流體94為暖氣或冷氣則視由該第二主管輸出之工作流體溫度而定。前述之熱交換模組之結構係屬本領域之人所熟知的技術，在此不作贅述。The indoor heat exchange system 42 includes a heat exchange module 420 and a blower 421. The heat exchange module 420 is configured to provide a first conduit 4201 and a second conduit 4202. The first conduit 4201 is coupled to the pump 41 to provide the working fluid 91, the second Line 4202 provides an ambient fluid 94 drawn from the indoor environment 43. The ambient fluid in the second conduit 4202 exchanges heat with the working fluid 91 in the heat exchange module 420, and the heat exchange module 420 transports the working fluid 91 back to the first main pipe 20. The exhaust fan 421 is coupled to the second conduit 4202. The heat exchange module 420 extracts the ambient fluid 94 and transmits the ambient fluid 94 that exchanges heat with the working fluid 91 to the indoor environment 43. The ambient fluid 94 delivered to the indoor environment 43 is heated or cooled depending on the temperature of the working fluid output by the second main unit. The structure of the heat exchange module described above is a well-known technique in the art and will not be described herein.
要說明的是，雖然第9A圖之實施例中之泵浦41與第二主管22相耦接，但並不以此為限制。例如，如第9B圖所示，在另一實施例中，泵浦41之進口連接熱交換模組420內之第 一管路4201而其出口則連接第一主管20。藉由第9B圖之連接方式，可以避免泵浦41接收由第二主管22輸出之高溫工作流體91，進而增加泵浦41之壽命。此外，要說明的是，雖然第9A圖之實施例中，該泵浦41係與該第二主管22相耦接，該熱交換模組420與該第一主管20相耦接，使得工作流體91由該第一主管20進入，再由該第二主管22流出，但實際上其流向並無特定限制，例如：在另一實施例中，如第9C圖所示，可以讓該泵浦41係與該第一主管20相耦接，熱交換模組420與該第二主管22相耦接，使得工作流體91由該第二主管22進入，再由該第一主管20流出。在另一實施例中，第9C圖中環境流體94之流動方向亦可相反，此時以一送風機取代抽風機421。It should be noted that although the pump 41 in the embodiment of FIG. 9A is coupled to the second main pipe 22, it is not limited thereto. For example, as shown in FIG. 9B, in another embodiment, the inlet of the pump 41 is connected to the first of the heat exchange modules 420. A line 4201 and an outlet thereof are connected to the first main pipe 20. By the connection mode of Fig. 9B, the pump 41 can be prevented from receiving the high temperature working fluid 91 outputted by the second main pipe 22, thereby increasing the life of the pump 41. In addition, in the embodiment of FIG. 9A, the pump 41 is coupled to the second main pipe 22, and the heat exchange module 420 is coupled to the first main pipe 20, so that the working fluid 91 is entered by the first main pipe 20 and then flows out by the second main pipe 22, but the flow direction thereof is not particularly limited. For example, in another embodiment, as shown in FIG. 9C, the pump 41 can be made. The first main pipe 20 is coupled to the first main pipe 20, and the heat exchange module 420 is coupled to the second main pipe 22, so that the working fluid 91 enters from the second main pipe 22, and then flows out from the first main pipe 20.
